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!
