Basics of Drill Selection - Haas University

In the inaugural episode of Haas University (Haas U), Manufacturing Engineer Andrew Harnett guides you through the basics of selecting the proper twist drill. You'll learn about the pros and cons of choosing high-speed steel, cobalt, and carbide, as well as advice on coatings, drill point and flute geometry, and more. How many times have you just grabbed the closest drill without really knowing if it's the right tool for the job? After watching this video that should hopefully be less of a problem!

Forget the CNC machines; sell us your Tool Crib Attendant Taming System! Richard was civil, knew what you wanted, had stock *AND* got you the right stuff first time?! Musta had something to do with those flux capacitors.

I'm a 70 y.o. housewife, and watched this whole thing with interest. I love learning new things!

This is probably the most informative, no-nonsense, and to-the-point instructional video I have ever seen on YouTube. Anyone wanting to publish help videos should use this as a template.

So many videos end up being advertisements for a specific product or service. Haas just dumps a bunch of very useful information, and a few things to think about. Fabulous!

Thanks Haas!

Isn't this an amazing presentation?
Many machinists grow old and retire and still have no grasp of this technology.
Many thanks.

Wow, this is the ultimate short course on drill bits... with no filler. 10/10

[WaynePilot]

This can't be a YouTube video. This literally is a college lecture for material engineering.

I can't believe how good the production quality was on this video. Your use of the diameter visualizations, chip evacuation, helix angles, and through tool coolant holes was really effective at getting your point across.

It's 3:30 am, I am a teacher for english and geography. Tomorrrow is a big day, and yet, I am AMAZED by these tutorial videos from Haas Automation and I can't stop watching them!

[devianb]

This is without a doubt the most comprehensive guide to drill bits that I have seen. Answered all my questions and then some.

[AjvarD]

This person told about drills as if he is Sergeant who tells his squad about new type of weapons.

[obaidmengg]

Just started the video but the first thing I want to say is Thanks. Really appreciating your effort. Keep enlightening the young minds.

[deanii]

I work in drill bit production and I have to say this would be an amazing video to show every employee at orientation. Super informative, thanks.

[billmccandless]

everyone needs to remember that whether it is a CNC machine or just a manual drill press you are not buying drill bits you are buying holes. How much do you want each hole to cost?

[BobJones-crpl]

From someone who machines parts EVERYDAY This is an excellent and VERY informative video. Thank you Haas.

0:21 Damn, Richard is awesome. He knew what the guy needed before he even said anything.

[jamesjacobs]

I've been bus 'tin drill bits a long time in my automotive machine shop, but thank God for the MAC guy! Hope he appreciates me watching this video now.

[BigBoyPharma]

I am a pharmacist... I dunno why im watching this but its fun

[stevebell]

I now know more about drill bits than I know about anything else in my life, and I've been a computer tech for 30 years. Damn, that was a journey. Thanks dude!!!!
