Basics of Drill Selection - Haas University 

You would get along swimmingly with my girlfriend. She's better with power tools than I am andIworked at a hardware store for a decade.

I should of married you,I been in a family business since I was born

Sup turtles!

DUH HELLO AvE

Uncle!

I was just about to ask if they had any extra flux caps I could buy...

Deary me, Ave gets about!

Hi there Mike. Hoping that you are well. I have to say that I absolutely agree with you. I have watched quite a few videos and I have found them to be at the best of times umming and ahhing. This is a superb video because it gets to the point. The only thing that I would so and it is a minor niggle is that the bloke is really serious looking. LOL. Otherwise, you are spot on about the video being a template for others to use. Bye4now...

agreed... he has the right stuff... no bs.. no childs play.. no politics... no bad habituation... just clean and strong.. this is the style we need to see in all of them.. and a lot.

Sergeant! Haha

He does come across as a drill sergeant.

Wayne ask for a refund, bud.

RU-vid University is a better value than actual college.

@@iviaverick52 100% true

Will it is one and if it's a college lecture for material engineering then people who do that job can come here too right? Think with your brain human.

This is actually a lecture ;D

A detailed look into coolants would be good.

James, If you do a quick Google search on Machine Tool Coolant you'll find the 1st video links are probably to several of the coolant related videos we've made. Or you can click here to go to the RU-vid playlist for our Coolant Series. ru-vid.com/group/PL1FfK7Yod27fuiQ4ZSRAnTT7Ut0wJCGRP

Very well laid out presentation.

This series of videos is fantastic, Very professional, suggestions, Drills specialised (hole making), Reams, gun drills, long drills, indexable drills, boring drills, boring heads. Why boring head is more accurate vs interpolating ect. Drills with replaceable tips End mills, (solid 1 piece) 1 flute, vs 2, 3, 4,5,6,7,8 ect helix, variable flute, radius on corner benefits vs sharp, Difference between macro, micro and nano grain carbide (carbide vs filament in material, why nano lasts longer than macro and micro ect.) Please include all types of milling strategies that can be included, helical, copying, contouring ect Special mills - Ball, Bull nose, tapered and what strategies they perform better at ect Taps For taps include the major difference of geometry that include the sworf direction of travel - Blind vs thru, include the 4 thread milling operations - thread cutting, forming, milling and punching. Include ones that need no hole for thread milling? Insert mills , (90 degrees vs 45 degrees vs 10 degrees high feed, buttons) Why the geometry is important for difference feeds ect. The 4 machining strategies in milling, conventional vs high performance cutting standard vs high performance cutting trochoidal vs high speed cutting trochoidal... Explain why chipload is different in these types, why past below 50% radial cuts you get chip thinning ect Non ferrous vs ferrous machining and rules of thumb, plastics Exotics materials. Advanced machining - High surface finish machining, "peening" machining, and using the harder materials above carbides (ceramics and diamonds) Keep up the good work

Haas Automation, Inc. Face milling with insert carbide plates would be an interesting topic?

Yes. That was interesting though!!

Yes he does come across that way, lol.

it got through my thick skull .

Drll Sergeant

I wouldn't be surprised if the tattoo on his forearm was military related.

Still will be hanging pictures/items in drywall at home! Why not know the ideal flute length to maximize your hole precision? ; D

Be in in by

Knowledge is golden!...I'm a machinist have looked at pharmacy videos!

Because every man must to know how to make a hole.

some of your patients need holes in their heads?

Thanks for the comment Obaid. We are definitely hoping to enlighten young and older minds alike. As always, the comments we receive are enlightening as well.

Thanks for the compliment Bob!

Thanks Nerdly! We're pumped that you're pumped.

Colonel Miles Quaritch Saftyspecs is a formidable foreman .... Wouldn't want him breathing down your neck.

@@haasautomation Seemed like an (US/ RU) army drill, lol. Totally worth it, i'm from east-EU btw👍

Bill Mccandless That can apply to everything.

Manual drill press you better have all self centering or split point drills if you want to be efficient. They take alot less pressure to get thru the material. Much much faster. Tip will tend to chip more in harder tougher materials than standard point. They also tend to size holes better unless you are trying to get a thou or two over the drill size then use standard point.

Nick Bowling all we stock in our tool room are T4 split point up to 1/2 inch. Everything over 1/2 inch are silver and Deming half inch Shank.

Yes Bill, exactly. How much does each hole cost?

Bill....Stfu with ur stupid theories

yes and with the cheap sound effects 😂

Lime, Thanks for the comment!

Go to O'Reilly Auto Parts' website and search 121G.

We have one on our vf4ss. Parts are done before we can close the vice.

Good eye Jimmy! That's great! LOL

Had to reverse time to go see it again.

wtf is flux CAPACITORS ?? im kinda new

I have a metalworking guide book that has graphs about that. I think you can order that online

Every metal or alloy has a set cutting speed, the harder the material the slower the cutting speed. A standard formula for machinists is 4 x cutting speed divided by diameter (of your cutting tool). If using carbide you can triple the result. And all this is just a standard starting point, final numbers will depend on your set-up and machine. There should be plenty of material online whether in video or book form to get you ballpark numbers.

Maxim, Спасибо за большую похвалу! Мы прилагаем все усилия, чтобы дать объективный контент, который будет полезен для наших зрителей.

itsgalf, Thanks for the great comment! It does take time and effort to get good animations done correctly. We don't do it everywhere, but where it seems like it will help we strive to use animation to make the subject easier to understand.

Thepriest39, thanks for the comment.

By the way, why is the TiCN Bluish? Then again, if it's blue, it's the good stuff!

Just remember who you are working for. What did you say? Awe well I’m just saying they need to remember they work for you tuco.. u think they dnt know that? Your think they r stupid? U think I’m stupid that you need to talk for me? Naw tuco it’s not like that... POP! Pop pop pop pop on and on... “Whoa!!!” “Look at that” then crazy laugh.

Tea Time, Thanks for the compliment. We're happy to hear that these videos are well put together.

A1BASE : Right on sir. I'm also primarily into woodworking with a farm background and and just a smattering of machine shop work. And I watched the whole thing, beginning to end !

Thanks for the great comment David, we're glad you got some helpful information out of it.

Also gun drills, for extremely deep holes. Though that would be a whole other video.

For gun drills and very deep holes we always drill small and circle mill a pocket to resemble a guide bushing. Works great for keeping deep holes straight as possible

I'd like to hear a reply on this too. I was taught to spot drill with a smaller angle for HSS and Cobalt, and a larger angle for carbide. The reason given was that for steel drills (less stiff), you wanted the lips to touch first, for best self-centering. Carbide is stiffer, and doesn't need the help, plus it has a higher tendency to chip if the lips touch first, instead of the chisel point.

never heard that one before. All drills should begin cutting at the chisel point. the spot drill angle should match or be greater than the angle of the drill. This In the Loupe blog from Harvey does a good job of explaining the process. www.harveyperformance.com/in-the-loupe/choosing-spot-drill/ When spotting, you want an angle that is larger than the twist drill’s angle if possible. The narrower the spot angle (i.e. 118 to 60 deg spot drill) , the more likely cutting lip contact will be. If the twist drill’s cutting lips, or flutes aren’t perfectly sharpened, one will contact the spot hole before the other and the drill will try to deflect. This defeats the purpose of spot drilling and can result in a less accurate hole. The broader angle of a true spot drill, (I like 140 degree angle tools) means the tip of the twist drill cuts first, which makes for a more accurate hole. Lastly, the web of a spot drill is typically thinner than a center drill, so it cuts more easily and with less heat.

I believe Harvey tool only makes carbide drills, and that article is written in regards to carbide. Guhring, who I think is one of the best drill companies, says differently. www.guhring.com/Documents/Catalog/Drills/NCSpotDrills.pdf

For drilling extra long holes with more than one drill bits it is suggested to drill the pilot hole with left-handed drill bit before the normal right handed extra long drill bit. See: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Trx99-oT2R8.html 8:08

tomte47, Great comment. From our experience here at the Factory with customers converting to using TSC and carbide, not to mention what our tool suppliers tell us about their similar experiences ..... TSC and carbide can be a game changer when it comes to drilling more productively.

I literally just find this to interesting to stop watching.

understanding drill bits would be lifetime beneficial, not just your current semester. that being said, hope you didn't flunk your test.

May be you are destined to become a machinist instead of a mathematician. Or may be nothing. Lol. Get yourself together.

You ultimate procrastinator

Wait omg 😂this is a college. Hahahaha love it.

It is the engineer inside you calling

@@jbbudish - thx! :)) God bless!

Not sure on the timing yet, but we're looking into the best way to package some or all of this info in a PDF document.

@@haasautomation Any updates in that regard? It would be really helpful!
