Incredible 40XD Deep Hole Drilling in Stainless | Kennametal SGL Drill | Vlog  

TOOL HOLDER: Erickson Standard Hydraulic Chuck Holder w/ Kennametal Hydraulic Chuck Reducer Sleeve. No Torque Wrench Required because it Bottoms Out when Tightening. PS. Runout on the exit was less than .002 PSS. I programmed 1 set of holes and then just ran 3 times for the video. At first I was just going to do one hole... but thought I would add a few more just to show you the consistency. Drill Info: 1.

I like how you are putting in a Metric conversion of your speeds now, I no longer have to do an automatic conversion from Imp to Met which is handy. This drill may be useful for our company as we have just got a Mazak i400 Intergrex which is probably going to a fair bit of deep hole drilling. Thanks for the video Titan.

If I could get into the matrix this would be one thing I’d download the knowledge of haha. CnC is amazing

Thank you!! I'm teaching my wife how to run my custom built mill with these videos.

Love ur channel just the way you talk and make sure your words are super clear kills me

Been marching 36 years fist time to see this amazing job glad I came by this channel great info

I love that sound when the drill winds up and starts making chips. We use this kind of drilling for waterlines with the molds we make. We drill into aluminum so we wind that sucker up and just plow through the material. Takes less than 10 seconds to drill a hole 11 inches deep.

really wanted to see what the surface finish looked like on that hole. very impressive drill regardless.

Love the details in this video , never thought about the tip angle for pilot drills . Your walking on water brother ...

Well, that was new to me! The way they move into the pilot makes soooooooo much sense! I´m gun drilling plasctics on my haas lathes and i think, this video gave me a proper way for straight borings anyway! Thanks for that! :)

Been a while sinceI've watched one of your tutorials, now that's a fine machine tool you have there and 40 x D is amazing. .

This is the best explanation ever on how to make deep hole drilling. top.

Titan I love your content . You are one of the best educaters.

I do holes like this all the time in 316 on a manual machine.. altho this is cnc i still learned some helpful tips. Thanks, great video!

Some very interesting techniques your company makes use of, brilliant work there too! I'm trying to learn more CNC and never fail to find more to see. Subscribed 👍

Thanks for video, Titan. We will use this example for drilling calibrator tool on DMU070

Tyson nice stuff I have done many many deep holes with another brand . 2 important things really need to drive home a) Coolant 100 % important and pressure in the early days Y2002 chip removal and coollant type major factor on horizontal machine. Causing breakage in TI switched to Vasco 1000 no breakage better flow no heat at tip or traped chips also program slight dwell allowing HP Pump to kick in b) Tool change if have option for tool type during tool change make sure you use heavy tool option on smaller tools 3mm and below in some cases on horizontal machines the force of tool change can cause tool breakage. That said hope helps some nebees enjoy.

I love your passion! Great videos!

Спасибо за понятное практическое видео, коллега!

That was damn cool! I love these videos!

What we just witnessed was pure machinist art.

Plot twist: The coolant holes drilled through your drill are even more amazing.

That IS awesome!

then someone forget to remove the toolchange, and the automatical toolchanger breaks the drill.

Damn that is satisfying, especially when you've drilled holes like that by hand.

Kaboom... Very nice... Another wonderful video

Gotta love thru spindle coolant ....

厉害了👍

Awesome🤩

Awesome. We do a lot of 20xd on our lathes. My butt puckers every time.

THAT is ONE very LONG sword u got there MR, TITAN

Edit: just saw the updated pinned post referencing .002 run-out at exit. Original question: What is the lateral deviation from start position to exit hole? Is it truly 'perfect'? Or under a tenth? I've always had trouble with small amounts of wander but these drills look wicked cool. Even if you're a tenth off over 12 inches that's well within what I'd need. Checked the link you provided and while expensive, I think these drills look to be the ticket. Thanks for another awesome vid.

AWESOME

Hey Titan, I'm in the automotive plastic injection tool industry. Sometimes we get situations where we're roughing or finishing oddly shaped lifters and slides that are decent size. A lot of videos showcase very small shapes or low complexity operations. I'm wondering if you could make a video showcasing a longer style rougher and/or finishing cutter on P20 steel. Some new tech getting hard to reach areas with accuracy and efficiency. Thanks!

Love drilling ma253 stainless

What a monster drill :)

I'd like to see a video on feeds and speeds. I'm new to machining and my biggest problem is finding out the fastest my mill can cut mild steel with a max spindle speed of 2500 rpm. So many variables, material, type of tool, number of flutes, rigidity, spindle speed, motor hp. Etc...

just ......BOOM!

"Muterial" I got a job as a machinist in a Cincinnati milacron 3spindle 5axis Gantry.. fanuc controls, any thoughts?

now it just went down for real today folks nothing like deep drilling and thats what she said !!!!!!

So. How was the tolerance from top to bottom ? Did it go straight thru ? Always seems to be the problem when drilling with long drills.

Can you do a similar videos on micro drilling? I often have to do .025"-.032" holes in 316 to a depth of over 15 times the diameter. I've had trouble getting reliable feeds and speeds and end up breaking bits off in the hole. As a result I started doing that feature on my micro drill press by hand. Good video. Please keep it up.

Serious question. How many drills did you break before you found the perfect speeds and feeds?

Impressive chip control for 316 SS

Hi Titan, your videos are very helpful, is there any chance you could do a video for machining duplex and super duplex like you have for inconel, hastalloy, monel etc?

I want to see them (manufacturer) drill this drill for through coolant! Crazy! Someone gave a video for that?

if i don't have a thru coolant drill, can i use the same method as what you showed??

Is it wrong that I'm turned on? Haha awesome video, Titan!

According to the screen, the IPR for the long drill is actually still .003 inches, because BOTH feed and spindle speed are now at 10% those of the pilot drill. Thanks for making these awesome and inspiring videos. Also I’m curious about if there is a way to turn off side coolant and turn on through coolant during the drill cycle, or if it was done manually.

Hey Titan, thanks for sharing another great video. Now wouldn't this drill qualify for a Abom79 badge? Well, at least for CNC side of things :)

Can use these drill bit on cnc turning center with main spindle rotation?

How would you go about drilling a through hole in O1 tool steel with drills under an 1/8th going over 20x Dia?

I use GUHRING 40 and 45xd drills in 6.3mm dia in the OEM automotive mfg field. I've made some improvements on the typical deep hole drilling cycle for increased efficiency. CODE BELOW. I also don't engage nearly as deep OR as slow. I drill over ONE QUARTER MILE of material with drills like these before sending out for resharpening at the manufacturer. .400" of pilot depth .300" of drill engagement, enter piloted hole at 20 IPM/400 RPM and don't turn the 1100 psi TSC off when entering or exiting holes since it does not affect how the drill enters the pilot hole at all. Using regofix holders I have a few tenths of runout at 12 inches of length on my Okuma M560V's. I feed and retract in G1 to prevent the momentary Z axis stop at the bottom of BLIND holes which causes extreme edge wear as the tool unloads and "whips" but there is one thing that really improved efficiency: (in G1 mode) I program so the machine feeds down to hole bottom, once at hole bottom I command the machine to feed up to the -.300" pilot engagement point WHILE SIMULTANEOUSLY slowing the spindle down without looking for spindle speed verification before moving to the next block- this makes it decelerate at hole bottom, then re-accelerate into retraction while simultaneously slowing the spindle so the drill doesn't whip around at hole bottom as it's unloading from Z force and slowing down in RPM. Once it reaches the engagement point I have it verify that the spindle RPM's are back down to 400 before pulling out of the hole which usually does not require the Z axis to stop moving except on shorter holes so movement is very smooth throughout the whole cycle. Not every controller is capable of such fine tuning but I was able to set this all up in my custom post processor. Those small tweaks shaved seconds off of cycle times and increased tool life significantly comparing to just G00 rapiding out after slowing the spindle down at hole bottom. Some materials may warrant edge radius modifications to the drills, such as cast iron* (high perlite content) and other gritty cast materials. Special drills with edge radius DOUBLED my tool life in cast iron. CODE for reference for any okuma guys: N8 (HOLDER - 3.15" REGOFIX PG15) (OPERATION NO - 2) T8 M366 A-78. C278.

Nice! I wonder how it would do in T1.

Hi Titan, did you measure the positional off-center error of the outgoing hole? Which minimum error can I specify on the drawing, without driving you nuts?

Sharing this information is great but for those of us that do NOT have TSC, & exotic tooling.. Can this be done another way ?

You should do a video about small diameter gun drills and trick to keep them straight.

Titan I have a request on behalf of whoever having the same query Can you make a video for that. Materials range and code description for tooling Tools flute helix angle relate to machining part material?

More turning!

Hi I have issue with step drilling tool which found oversize in auto cycle after remove tool and clean tool and spindle then diameter is on the mean.

GUUHHHHRRRRIIIINNNNGGG

What about grinder machines and everything involved with them?

How do they put the coolant holes in the drill bit?

Do you dwell at the bottom of the first hole to ensure a perfect nice surface for the 40d? Thanks

Hey Titans on cnc team do yall have experience drilling incoloy 901?

I was wondering, did you manualy insert it into the spindle or with the toolchanger. I would guess first since most tool pockets dont have that long space as well as the force of the toolchanger could damage the tool.

Titan. Would you ever consider offering your training tool kits to people in a hard spot trying to get themselves up to the next level?

tomorrow I will be drilling some 0.12 mm holes on a 24000 rpm spindle mounted on manual milling machine! It's high precision and sensitive...and I have no ideas about the holes I'm going to drill and how to engage!

I'd love to see the CAM for this

what if you have to drill throgh a 70 inch long part I suppose that then you will drill for 38 times the diameter (I left 2 for safety) and flip the part or rotate the c axis and drill the rest but my concern is in the break through the non plane surface won't that cause any problem?

According to Novo Kennametal for this drill feedrate is about 10 times bigger and cutting speed as well for stainless. Vc 40 m/min and Vp 127.36 mm/min. Titan Could you explain why did you go down so much?

Titan, have you ever used TX drills?

Had to use a 40x HHS uncoated (all we had in the shop last night that would reach) 9/32 drill in copper today and could only make it 3, 9 inch holes before needing to be reground. Was a long night.......

What’s the best drill for deep holes in ductile iron ?

Yes , but do you dwell when switching stages ? , and how much

I've been using Walters 6mm 50d, it's a beast.

anyone play these videos on 1.25x speed? old mate titan talks so bloody slow! maybe we just talk faster in Australia

Ever considered making a Curta Calculator?

Could u show us all the different materials what they are called tensile strengths and the different bits used for milling pls

I always heard the tip angle of the pilot needs to be exactly the same as the deep hole drill. Your explanation makes sense though, it makes the drill ease into the cut more. Great video Titan!

How is the coolant line made? Through extrusion of the blank or using an even higher ratio drill?

Beautiful! Love it. Viewer request ... you mentioned automotive industry in the video. I would like to see how that industry, maybe uses this 40xD drill to bore drill a crank, and the oil passages in a crank. Maybe the larger crankshafts a for large diesel sea going vessels .... Thanks for sharing and teaching!

I'd like to see a video for drilling 17-4ph H900. Ive been told it should be treated like 4140 at ~30HRC

why did you have flood coolant on?

Estas brocas con el afilado a 140 grados en ángulo de punta son un producto de la antigua Empresa Hertel Alemana

Kennametal has a 72 x D diameter lenght drill called HP drills, would you ever try it?

Can someone explain to me how to create a really long injection molding barrel.

Oh man, if I could only drill a 20” barrel with that

Its hard to stress the being careful about chip build up at the top of a hole in stainless enough. I've always wanted to program a macro similar to g83 but for stainless. With smaller machines without the hp the chips get stringy and if the rapid is at 100% you can run into problems with chips at the top of the hole while reentering the material. The only way to fix that is to put rapid at 25% or program a subprogram.

Did you have to hand load the drill due to it’s length?

How about with 15-5 ph or 17-4 ph at H1025?

Thru coolant drill are freaking awesome over 8200 holes 3.2 dia drilling 7x dia in 304 stainless.

I faced some problem while drilling HSS drill in STAINLESS STEEL material Chip breaking issues as well drill overheated Vc=20m/min F=0.1mm/rev It really worst case with SS

What kind tolerances can this drill produce?

It would be nice to see how much did the drill walk, and it if the upper diameter stayed the same.

Is that still good for copper? At work we’ve got a project requiring cooling channels deep into copper.

I’m currently doing so 50xD holes in 42CrMo4 steel. 8mm 400mm deep. Spilt point twist drill. Pecking away. Job in a horizontal position. Fun stuff.

Very cool! How much for the long drill?

How come you didn't drill the 3 pilot holes first before 40x dia drill holes?

How was the wandering? How close to true position was held?
