The Drill America 59/64in HSS drill bit features a 1/2in shank with a 3-flat design for secure chuck grip. Its heavy-duty split point geometry promotes accurate starts and reduces walking on hard materials. The reduced shank construction allows use in standard 1/2in capacity drill chucks.

Buyers needing metric sizes or smaller diameters for pilot holes should select different bits. Those requiring carbide tips for abrasive materials or longer flute lengths for deep holes will need alternative tooling.

Questions about this item

What chuck size do I need to hold the 1/2in shank on this 59/64in drill bit?

A drill with a 1/2in or larger chuck will grip the 1/2in shank securely. The 3-flat design prevents slipping in a standard three-jaw chuck.

Will the 3-flat shank work in my older drill that has a keyless chuck?

Yes, the three flats engage the jaws of a keyless chuck just like a keyed one, giving the same anti-slip grip on the 1/2in shank.
