Read the instructions! I run a very high volume Small Engine Repair shop and use my Drill Doctor 500x on a biweekly basis for the last 3 years and I'm still on the original stone. The stone doesn't get hot and I use M7 molybdenum & cobalt bits exclusively drilling 10 gauge steel up to .25" plate with great success. This machine creates a very repeatable sharp true angle split point in half the time it took me with a grinding wheel. Time is money.
I have been using a drill doctor for many years. When you read the directions on how to set up your drill, it works perfectly! I have sharpened at least 300+ drill bits. Once you learn how to set your drill, there is no better way to sharpen it. Carefully read the directions!!!!!!!! I love this and highly recommend it.
I have one of these, once you learn the system it's very easy to use with repeatable results and handles size variations in effortless fashion. Some bits will cut like new, others will be adequate. You can sharpen hundreds of bits with one diamond wheel, I've sharpened dozens so far with no noticeable loss in performance. Doesn't take long to pay for itself what with saving time and money not running out to buy new bits every few days. It's also much more portable than bench grinders, making it useful in the field. You're right that it's cheap in all the right places which really just makes the tool more obtainable.
My experience was different. I followed the directions, sharpened my cobalts, and the results were so good, I'd redo new bits before first use. New tips on broken bits, etc.
I’ve been watching AvE videos ever since I accidentally discovered them and usually find them entertaining and educational, sometimes even insightful. But let this be a lesson to me, cause you’re way off on this one. Our drill doctor has been great! My bits are easily as sharp as new, or maybe even sharper than new. Since I took the time to read the directions, and use the the tool correctly, the one that sat in the shop gathering dust at work, is for the first time, being used to do exactly what it bought to do. My boss didn’t have the patience to figure it out either. This tool has been very useful and still going strong after hundreds of uses. Worth ever penny that I didn’t spend on it.
Direction wouldnt change if hot and neutral are swapped. Its AC, so it doesnt matter. The only thing that sets direction on a universal motor is the polarity of the field coils with respect to the rotor. Thats actually a permanent magnet DC motor, usually whats used inside hair dryers etc. The bridge rectifier is what allows that motor to run on AC. It will be electrically noisy though, as the DC from the rectifier wont be smoothed at all.
Yep. Rectified unfiltered DC being fed into a little DC motor spinning its literal gutz out, arcing and sparking like crazy. The wave form drops to zero every 1/100 of a second, and the motor is an inductor, with the commutator acting as a switch, causing huge amounts of RF noise.
Colin Smith Let me add something to the discussion: The worst part of the noise created by the commutator should be suppressed with caps connected directly to the commutator in a star fashion (they will spin along). This removes the noise much better than any external cap or choke. I have tried. The input voltage "going to zero" is not correct. When the mains voltage goes to zero, the rectifier disengages and the voltage on the motor is kept by it acting as a dynamo. This part is the worst source of bad power factor. His gadget surely only accounts for the phase shift part of the power factor, but the distortion of the wave is certainly unmeasured because this will have it very bad.
I have one of these. A friend left a big container of drill bits, maybe 100, out in the rain and didn't want to clean them up so he gave them to me. I cleaned them and then sharpened them all on my Drill Doctor. Everything from as small as the collet would hold to 1/2". It sharpened them all and did a good job. All those bits cut well. If you learn what the positioner is doing you can sharpen bits smaller than can be positioned using the built in device, as long as the collet will hold the bit.
I have to defend the drill doctor. I have the model 750 its a different model then the one you tested, but the concept is the same. I have used it everyday for the past 4 years and it has never let me down. It only takes 10mins to learn how to use it, "properly". In my opinion its the best value in my shop, and it is easier, and faster to use then my KO LEE tool grinder. Dale d
Waaaiitt just one minnuttte sir!! Hold the phone!! if you have to sharpen your spinny pokey bits EVERYYY day then don’t think It’s working very welll at alll!! Check mate!!!♟
I have one of these. Once you know how they work, you sharpen a bit in about 2 minutes taking your time. You can blame the tool but i'm a home diy'er and use cheese grade bits from the homeless despot and that thing refreshes them with the perfect angle, perfect grind everytime.
When I got mine several years ago I was trying to sharpen a 1/4" bit, and I had it setup wrong, that diamond wheel ground over an inch off the drill bit with no problem and still works great. I do not know what the drill bit was made of. I like this thing because I can sharpen a lot of bits precisely and quickly.
I have a drill doctor. Sharpened my dull bits when I first got it years ago, but since then it's mostly gathered dust on a shelf. It does work though and is a fairly well made tool.
I know you only do these things for a laugh but I did expect you to be fair. It wont sharpen diddly squat if you use the wrong alignment mark, the white line is for split pointing in the other hairless orifice. As you youngsters are often heard to say RTFM.
Dude. This is not billed as a "portable tool". It is billed as a supposedly superior replacement for a pedestal grinder with a drill sharpening jig on it like every real metal shop has had in the corner since Christ was in diapers. :rolleyes: Just... ewww.
I had a similar experience with the drill doctor, there is definitely a learning curve! When set up correctly you don't take very much material at a time and it works well. I tried to cut the split point but it didn't go so well. I'm sure with a few more tries, I could have made it work well. Pay attention to the positioning instructions, obviously the most important part.
I was given one of these, learned to use it in 5 minutes and sharpened a big box of old bits razor sharp in no time. Not sure I would buy one myself, but have no complaints about the function and results
This here. AC line changes polarity by definition. I'm going to guess that the motor is actually a permanent magnet, not a series wound universal motor and thus needs dc not ac.
If you knew anything about motors, you could tell just by by looking that this is a PM motor, therefore DC only, hence the rectifier. AvE's power meter is calibrated (they ALL are) for 50/60hz with a pure induction/repulsion AC motor; the Power Factor is completely out to lunch on a DC motor being powered with 120Hz pulsed DC from a bridge rectifier.
Love your videos. I got me one of those drill doctors and two days after I got it I learned that you could sharpen bits on a bench grinder. but anywho I decided to keep on using the drill doctor which if Done Right makes the bits look like they're fresh out of the package. cheap bits, expensive bits, wood bits, metal bits. I've had mine for 4 or 5 years and it still works really well
We got that thing at work and it's always been a pain in the ass to get a perfect grind on. I only use it for small drills because those are harder for me to get ground perfect by hand. Definitely gotta learn the proper way to use it though or it's just gonna make the bits worse off then when you started. Once you got it figured out it's not bad to have around. They guys at work that don't know how to sharpen a drill bit by hand use it often. Funny review, I got some laughs out of it. :P
Abom79 Guess we come on AvE's channel more to see what he thinks of something, than, in this case to learn how to use the guizzmo, hand sharpen drill bits or even being shown how a decent bit has to look like to perform.... ;-)
Abom79 I agree. I also prefer the DD for those times when I sit down and sharpen the bucket of dullards all in one shot. Once I remember how to use the damned thing it does a good job and I like splitting the points. But for that "need this bit to get the job done" situation I'm happy that I've learned how to sharpen by hand.
+Abom79 just an fyi I noticed that the grind on my bits was always different than what was on them from the factory so i called drill dr and they told me that the xp mdel is set at 118* more like 120* but my bits are 115* i am talking cutting edge not relief..but i was told the 750x model lets you change the angle from 115*-140* just thought i would share what i learned....
I have a 750x and can confirm it's nice to be able to adjust the angle so you're not grinding for days the first time you sharpen a new bit. On the other hand, it's nice if all your bits have the same angle so you can set the Drill Dr and forget it.
AvE I have a Drill Doctor, I have the big one I can sharpen drills up to 3/4'' since maybe 7-8 years and it works very very good. It is an easy user wen you know who to use it. I love it, when I have bigger drill I use my bench grinder. I sharpen drill bits almost every day just to refresh the cuts and it is perfect. Since I bought it, I have changed the grinding wheel once about 3 years ago and I have one spare. Like your video, keep upth good work. Louis Alleva Quebec Canada.
Same. Electrician in CT. Been using the Dr. for years. You have to spend more than 20 seconds reading the manual if you want to use this thing the right way. I love this dude and this channel but he really didn't try to learn it. Son of a diddley.
I have the 500X and it does a great job on my drill bits, but then I do read ops manuals! I get that perfect spiral of swarf! I could never get a consistent grind on my bench grinder. Another great teardown video!
Honestly, if you do it right, this thing will make your drill bits look purdy. My teacher showed me this in class and took a drill bit from dull to sharp in 1 minute. I'm not saying it's better than a bench grinder but in some cases it would be better to pop the bit in this thing instead of fiddle around at the grinder trying to get it even
Yes. Plus, you can't always have a bench grinder in your work truck. I keep the drill doc in my work truck all the time because if I'm using a 2 foot long bell hanger bit and I wreck it on some unseen concrete, I have to sharpen it immediately or my entire day is fucked.
I have used these before. They work excellent for less expensive bits and will sharpen dozens of them without showing signs of wear on the grinding wheel. Another already said you have to set up the bit position right, but once you figure it out it works wonderfully. I have sharpened bits with these that cut better after sharpening than when new. You can also grind to new angles, which is great for tailoring your drilling needs. Even the split point grinder feature works well.
I have had one of these for years. Plastics aside I find it very useful and it has saved me shitloads on drills. I may have a model that takes larger drill bits.
I also have the older style, which my wife picked up used, for cheap. I believe it will go up to 3/4" bits, and it has successfully sharpened hundreds of bits over the years. I've actually never replaced the diamond (though I have a spare). I've never understood why these get such bad reviews or why people hate them. Mine is fast, and fantastic. Also, mine is an all fiberglass reinforced plastic housing. At least that's what it looks like.
+russtuff mine too... he has a newer and cheaper model than ours which is now discontinued. Once an awhile the best products are made at the start and they get worse as more get made. Must be the case with this thing.

@tim - "than this dude can count" lmao! Ave would destroy you intellectually.. and your petty comment speaks volumes. BTW the drill dr is a 200$ plastic gimmick.
You were obviously having a bad day, I have used this tool for around 10 years and it is very easy to use and works wonders. You didn't have the bit aligned right and you were using too much pressure. Also I have never had to buy a replacement drum because you only need light pressure. I had a machinist measure the hole a sharpened bit made, and it was perfect. He was skeptical like you but soon realized it was a good tool that worked perfect. This tool has saved me tons of money by not having to buy new drill bits. I love your videos, keep them coming!! Good day I say...
I bought a drill doctor a few years ago and yes you should read the manual. i purchased the Drill Doctor 750 and overall I have been happy with the results. Getting the basic geometry of a twist drill down may not be that difficult but keeping the cutting edges the same length is the hard part. I have sharpened many twist drills by hand even modifying them for a special job, but the Drill Doctor will give good to excellent results with less headache.
Please read the instructions, practice and do the video again, you'll be surprised that it works really good. Por favor lee las intrucciones y has el video nuevamente.
Sometimes.... Ya just gotta RTFM! It's not just a depth gauge. Once you get the nuance of the bitey springy things to align the flutes on the bit to the cam on the collet... the tool works quite well. Great, nah. But a quick regrind to save you a trip to the hardware store and ultimately more time for Mr. Molson, hell yeah! PS; I bought one for my dad many years ago. When he passed I inherited it back. Still on the original wheel/stone and still sharpens bits within 3 to 4 turns... When properly aligned.
Someone probably said this already, but if you swap hot and neutral you won't reverse the motor's rotation, since the polarity is switching 60 times a second anyway. The direction of spin comes from which side of the sine wave hits the motor first. Hence with a rectifier you are correct that the rotation will always go the way they need it to.
I've had one for over 15 years and I LOVE IT. Works smantastic! I've sharpened bits from 1/8" to 1/2" at least 100 times in my shop. I can confidently say therrs just a spot of finesse to the initial alignment part and then its a cake walk. Be glad to explain it if you want...! Cheers! Your shit is usually tons of fun and edumakashunal. Love the channel. Keep it up!
I have to say that I enjoy your videos immensely. However, I have owned one of these Drill Doctors for quite a few years now. I received it as a present long before I learned to grind by hand. It is especially useful on smaller bits where you'd need to get out the ole' jeweler's loop to grind by hand. True, I did have to spend a few minutes reading instructions and getting used to the cam operation, but it continues to be an absolutely invaluable tool in my humble amateur shop. If I get a Quorn built, it won't probably ever see much action again, but...
I'm impressed that you loosened up to "if you want a useless skill" from "it's completely a worthless device". I've owned that exact machine for a couple of years and it has resurrected many an abused carbide bit (Mon fromage de choix). It's perhaps not the best way, but it's got better documentation than a bench grinder.
had mine for about 10 years and it work just fine even sharpend several broken bits back into a working drill bit..need to learn how to use the pos first lol
Woodworker here. I own both the travel model (hooks up to your drill which is nice because it can be used away from 120vac power) and after using it for a few years I bought the larger indudstrial one (does larger bits, up to .5 inch ) because the travel one uses the red grit as a sharpener and wears out FAST. But there is good news: a) the red and diamond deals are just 1" drum sanders so they are actually cheap to replace you can get diamond ones at HF cheaply enough b) I've never had to replace my diamond one, ever and I have owned it over a decade. It's sitting onmy shop bench right now because sometimes I use it often. I pry do more metalwork than most DIY homeowners, probably like 5 times more. c) Once you learn how to set the tool your cutting/sharpening the drill will go way faster d) Trick is to advance the point just a smidge past where the jig helps you to do it. 1) The jig is set for standard sharpening 2) Yours was gone or broken... didn't see the before pic of the drill bit e) You used it wrong because you have to start with the mark aligned as it shows and rotate quicker and count in 2s until you stop. It must be a fluid motion from 12 o clock to 6 o clock. Then stop and regrip it from 6 to 12 in ONE SMOOoooOOOth motion. f) Once you get used to it it is quicker than hand sharpening. g) My industrial one stands taller and has more quality plus its thing that kept biting you is designed different so it never bites me ( get the indudstrial version, you'll see what I mean!) h) I like how you take things apart before you even use it. Reminds me of me. i) I'm as anal as you oh...j) The industrial one lets you sharpen at two angles which helps me in a lot of ways. I sharpen cheap steel bits steeper and then by looking at it I know only to use it for wood & The shallower angle I use for better steel and they drill metal great and work in wood, too. If you ever had to drill a wrist pin out of a car's front end you know that steel is next to impossible and this tool saves you going to the store for 5-8 more drill bits and lets me sharpen at home which saves time & money in the longer run. Really the thing paid for itself just on that day alone for me. I'm not much of one for gimmicks ( You BOUGHT a bench grinder, dude, I MADE one from a used washing machine motor, a farmer's arbor, a V belt, some 2 by 4s, some concrete and a piano hinge. Cost me all of about $7 for the belt everything else was recycled/reused/scavenged. I even made my own polishing and buffing pads. Oh, I did spend a couple of bucks on electrical switches and boxes but that is only because I used both windings and made a 2 speed grinder/wire wheel/buffer. Lately I even added casters so I can roll it out of the way in the shop.) and I will defend this thing to the day I die as not a gimmick. I think even the plastic on mine is better. Oh, I see...mine is discontinued (read the reviews on that one, MUCH better product... methinks yours was redesigned for "planned obsolence" & sometimes being the last one to a trendy item you pay that price. ) damn, it won't paste my link. Try going to drilldoctor.com and check out the classic model 500 & 750... but now that they are discontinued you'd have to find a used one and guys as smart as me will never part with it (nor would most of the reviewers I see who own these models) or you can just keep sharpening by hand.
+BikingMNViking the motor turns slower and doesn't bog down so easily, the amount of metal taken off per sharpening cycle is adjustable (end stop in the drill loading station), increasing or decreasing relief is straightforward, and they've completely re-done the point splitter so that it's no longer possible to oversplit the point. And a single chuck now handles all the way up to 3/4".
BikingMNViking Darex customer support sold it to me for ?$60? after I complained that the angle-setting finger loop on my old one had broken. I had to send a photo of the cut-off cord from the old one. The angle-setting on the new one is continuously variable, with two little depressions to screw the locking knob deeper at 118 and 135. It's the least successful feature of the machine as you have to tighten it hard and then it's hard to loosen. I made a knob with better grip for use with variable angles, just use the supplied knob for fixed. My original 500/750 had a very fast motor that required a very light touch to keep from bogging. Once I learned the light touch it was no problem. There may have been a production change in the motor, I think mine was a pretty early one. The new point splitter goes straight in, when it bottoms out you're finished. When you're not splitting there's a grit catcher that plugs into the hole, or you can put a vacuum hose there.
BikingMNViking I'd had it for years and years, more than ten years I'm sure. Yes, that's the one. I don't think Ave is interested in treating one of these seriously, he's going for laughs.
To be fair it's a surgical tool, not a brute force industrial grinder. It's got plenty of power & rpms for the purpose and then some. Diamond wheel is fine in my judgement because you're not removing much material and I don't think it gets hot. Anyhow I've had a smaller $50 model since Noah built the ark and the wheel is still pristine. It sharpens bits well so long as the alignment/adjustment thing is right for your bit. I think the twist on some bits have a different pitch than it likes - in that case the alignment's gotta be tweaked by eyeball and that's a trial & error game.
Not sure you gave this thing a fair shake. Sure, the plastic is wimpy, but it's enough to do the job. Sure, you could take the time to learn drill sharpening by hand, but you'd spend years developing the skill to do it reliably and consistently, every time. Or, you can use the Drill Doctor as a jig, which is what it really is, after all. It's no different from the guides you use to hone your plane blades and chisels at a precise angle, and it's actually kinda clever how the cam gives a little change to the grinding angle as you twist the drill. With just a couple of minutes, I've restored a lousy drill bit to smooth, fast cutting.
Have the same drill docter, it works perfect for me, especialy to center en sharpen the dril bit. So a drill bit of 5 mm wil give you a hole of 5 mm and not 5.1 or more mm! But you have to follow exactly the manuel of the drill doctor!
The base model of this tool sells for 1756.52 Thai Baht on amazon I have one at work, ( welding shop) it works fine. After reading the manual, (5 minutes), I sharpened a bit on the second try. I can sharpen a dozen 5/16 bits in 5 or 6 minutes. I don't understand the hate for this device. As for the consumable grinding drum, I'm still on the first one 2 years later.
God of Thunder I agree. The problem i that I usually use drill bits smaller than that, and for those, the chuck doesnt work well. I did some 1/2 bits and it was great for those. I find it works best on the masonry bits.
I've had a drill doctor for bout five years now, got it as a gift and didn't expect much out of it. Once you READ THE DIRECTIONS, it actually works very well. I use it to sharpen the smaller bits that my geriatric peepers don't no longer do so good with. Of the 150, maybe 200 sharpenings I've done since I sat down and read the manual, just about every one has been perfectly good. I can see in the video that our dear host didn't take 20 seconds to set it up properly and not surprisingly, he didn't get a good grind. Just goes to show, L2PTG! Yeah, there are a lot of useless gadgets out there, but these drill docs aren't one of them.
You'd enjoy the grinder my grandfather made that actually mounts to his tractor PTO. Good luck stalling a 65h.p. Diesel grinder. He actually made it for use with these gigantic polishing wheels, but it'd grind too. Ambulance optional.
Ron Schnaper No, not really. These frequently go on sale at Canadian Tire for $80 and the regular price is $160 Canadian dollars, which is about $120 USD.
angles and reliefs are different, for tougher metals you set the pitch to more than 118 degrees(the normal) Also if you work with bronze at all you need to have a flat, yes a flat on the cutting edge. This dressing will leave it scooped otherwise and your drill will squeal like Ned Beatty in Deliverance. You will still need to touch it up on a bench grinder.
thorinbane You're not from round these here parts are ya boy? Hey boy, you got a real perty mouth..... Sorry, had to do it. Thanx for the tips. Don't do much brass or bronze, mostly steel, aluminum and stainless. I found that if the angles are not the same the drill wants to walk and they don't cut good. You can feel the one side cutting and the other side kind of dragging. I am no sharpening expert, I can sharpen them on a grinding wheel but not nearly as good as the doctor. Definitely a skill to master.
thorinbane Thanx for the insight. I made a gauge a long time ago, but I need to get the technique down on the wheel. The nut idea is pretty cool if you don't have a gauge.
Got one of these a couple years ago and I'm pretty happy with it. Never took the time to learn hand sharpening, like the lazy ass I am. The drill dr works pretty decent though.
Funny video. Couple of things here: 1) The thing only cost $80 to $100 at Lowe's or Home Depot 2) If you follow the instructions, it actually works well. We started using it to recondition bits when we have to drill through 1/4" steel over and over again. 3) The thing is idiot proof enough that I can have a low level worker do it over and over again to keep my crew with "fresh" bits. 4) It is so much more portable than a bench grinder. I can take it to a job site and use it without taking up much space in the truck or on site. This thing has already paid for itself in the money saved on bits. I've recondition my carbide, steel, and masonry bits, and they have all performed very well after sharpening.
If you do it right (directions, hello ?) it works perfectly. I totally love mine and get top notch tips on them. It's been a while since I did my "go to" bits (since not a "daily driller") but they do need a touch up and I have a cheapo useless set of counter point wood bits that couldn't drill their way out of a paper bag that this just might turn into something useful. It's actually fun to use. I love it when things work perfect and easy !!
Your new vid tricked me into looking up your old vid. The CD Rom drive joke almost caused me an injury. Who needs TV, when there are grumpy guys on youtube growling out doggerel about tools?
I've had mine 9 or 10 years, and I bought an extra grinding stone with it. I've ground around a thousand drill bits perfectly and never have changed the stone. This thing is great. One of my favorite purchases. But everything's sharp and it just sits on its spot on the shelf.
It does take a little practice but I can easily sharpen the worst drill bits and make it look like new(up to 3/4 inch) using the drill Doctor. The same model in this video.
Anybody else notice that the picture of the drill bits on the side of the box shows left-handed drills? Someone in the art department doesn't know any better. XD
I bought a T8 last year and I have no regrets. I got the drill sharpening jig and i use it routinely. I tried all sorts of reasoning to justify the expense but in the end I told myself "I like nice things. I'm buying it"
Wait a sec. I love my drill dr. I think I only paid around $50 for mine. Works like a charm. The chuck on mine is super easy to use. All my drill bits are really sharp now and I use it regularly to touch up bits I'm using. Plus I can't sharpen bits on a bench grinder to save my life.... he he
My drill doc is good up to 19mm and I'm still on my first wheel. Mine came with a spare wheel in the box. I have had it for around 6 years now and sharpened well over 1000 drill bits. Remember that once the wheel is worn you turn it around and use the other side. I'm the same as Adam (Abom) I only use it for small bits as they are hard to do on the bench grinder (prob wouldn't be if I wore my glasses)lol
I have the model 750 and I took the time to understand the ins and outs of the thing. I have subsequently sharpened every drill in my family's possession. Probably 4-500 of them. I have a couple extra stones, but have never used them. I like this machine very much and if you can't use it satisfactorily, you aren't paying attention to the instructions.
I dont think hed have much to be salty about with guns unless he was buying rossi or other bargin basement knockoffs that he probably cant get there. Most guns being sold by companies people know the names of are pretty decent. Im sure there are some that arent perfect but most are better than decent.
I know that this is not a super high quality product but it saved me tons of time having to sharpen 30 - 300lb gorillas drill bits because they ran full speed with no cutting oil all the time. It worked well enough that I got the slightly upgraded model that does larger sizes for myself at home. I think it actually works well and it does well with the back cut on the drill bits that don't need a pilot hole. The one at the place I worked it lasted longer than I did. I moved on after several years of being there and it was still working well.
I use this machine weekly and I can tell you it is a skill you need to master the alignment jig that bit your finger is the key if you can get it right your golden ad long as you turn it with an even constant pressure when sharpening I have been told when I sharpen bits they cut better then new ones
+Loco Motives Actually there is such thing as aviation grade aluminium, I worked at a company that made wing ribs and they only used top grade aluminium. It was so good you could machine it using soluble oil, usually to machine aluminium you use kero
I've had a drill dr for close to 15 years. I just bought a replacement grinding wheel, but still haven't needed to change it. The only drills it won't sharpen are #30 and smaller. (Aka 1/8) It's been a damn good tool for me.
Well, that one must be defective or perhaps you're not holding it right, but, I've used one of these on an entire set of cobalt drill bits and every one of them had a perfect cut...
We had one in the tool crib on a large construction job, 1st I learned to sharpen drill and Lathe bits 40 years ago in a tool and die shop, I have not forgotten how and I sharpen my own bits at home and on the job. 2nd when I got put in the crib we had 100s of dull and broken drill bits. That being said, I learned how to use the Drill Doctor it will sharpen several different angles (as anyone with a week on the job knows 59 degrees is shit for steel and terrible for wood). I was able to sharpen the entire box of bits in my spare time on a mid shift. the points were consistent and the split point were correct.
@@pdxlockpicker7796 If you cant sharpen drill bits by hand with a bench grinder and need to rely on a plastique chinesium pos then I feel sorry for you.
@@lomparti yeah, but I won't get the perfect angle every time. No shame in using a jig that speeds up the time. I use a jig to mortise holes. Same concept. You can use this blind. Don't need to check your work either.
Bought one 7 yr's ago, used once and threw it in the corner and went back to free hand sharpening on a grinder that served me well for the last 40 yr's.
thanks for the laugh! I bought one of these a couple years ago and it's always been a pain in the rear. I also haven't taken the time to learn how to use a proper grinder..
This is one of those tools that most men wouldn't buy for themselves. Its a novelty tool that someone would give as a gift. I had one of these gems given to me 10 years ago. Its way too complicated to set up and use. I spent half a day trying to figure out how to use it (and never did) and destroyed 50 dollars in drills in the process. I got a good education from it though, I learned how to bench grind and I regifted that little pos!!!
Justin Turner So Fucking True !! Wtf ? It's about as Complicated as a Fucking Happy Meal. This is proof of just how far behind the USA. Is lacking in basic education !
I hate to chime in on poor Brandon but he obviously suffers from diminished capacity. Learn to read or at least look up the directions on youtube. They have great pictures. No reading required. One more thing, try doing a split point by hand. If you can do that you need to do a youtube video yourself.
I got one of these as a gift and I will run my cheap bits through it before drilling metal and it works pretty good. Over 10 years never replaced the stone. Clearly these are not meant for people in the trades.
Funny review, especially when you stab your finger! I've got a Drill Doctor and as long as you read the instructions and set the drill up correctly, it does sharpen pretty well. Looking at your results, you did not have the drill correctly positioned in the drill holder.
I see you've come to the same conclusion I did. Could never get the damn thing to work. No relief on the cutting edge. In my instructions they say that drill grinding is a skill and takes time to learn. Gotta love the machine advertised as the "easy way to grind drill bits" with a learning curve. You could learn to hand grind in the time it takes to learn to set this thing up right.
I sharpened a lot of drillbits in my life.. worked with a DAREX M5, which i was told was crap, did everything on that thing, up to helical point geometry and split points . Moved to a company where they had one of them drill doctors.. tried it once, told the boss to toss it in the garbage, taught my colleagues how to sharpen a drill on the bench grinder.. great savings.. the drill fuctor was never used again..you don't need a machine to mess up a drill
I have one of these too. Since I keep mine in it's storage box, it's faster to sharpen bits on the bench grinder til I have a number of bits that all need sharpened. Then I get the doctor out and do them all in one sitting. I also have the left hand bit adapter and it works very well.
I am a mechanic I have a skill to sharpen drills been doing it since 1974 about 10 years ago a buddy at work showed me how to use this drill doctor thing I have not free handed a drill in 10 years ave e your in a hurry slow down and watch the vajideo redo this bajideio
@bill russel You've had no love on this page for 4 years, how've you been these past 4 years? how're you holding up, and do you have any tricks for a young bloke for hand sharpening drill bits?
What tha friggg why every one sharpen their drills!?! Am I missing something my drills all have dull chucks at the tips of them or collets on impacts but DULL!! Dull!! is tell ya this is a conspiracy @ave run for the mountains save your self!!
I think why drill bit and saw blade sharpeners are made is for consistency for people like me who who have bad eye site and shake little bit. they are a good thing
I have a Drill Doctor, I haven't used in years. for small bits, I buy them from Harbor Freight and just dump them when they get dull, for larger bits,1/4" and above I find it is quicker to sharpen them by eye on my bench grinder. The Drill Doctor did work though, but I found it was quicker to sharpen the larger bits by hand.
reread the instructions carfully and look at the pictures I have one and I wound up with the same problem but then I went over the instructions and looked at the pictures and I love that thang it works great
