Drill America 53/64in Cobalt Drill Bit

This 53/64 inch cobalt steel drill bit features a 1/2 inch reduced shank for use with standard chucks. The bronze oxide finish reduces friction and helps resist heat during heavy-duty drilling tasks. It is built for professionals who need reliable performance in tough metalworking applications.

Replaces worn high-speed steel bits in demanding

Upgrade when standard bits dull quickly in stainless steel, cast iron or other hard alloys. The cobalt construction holds an edge longer under high heat, reducing changeover time on production jobs. Not suited for wood, plastics or soft materials where the aggressive geometry can cause tear-out.

Questions about this item

Will the 1/2in reduced shank fit my 1/2in drill chuck?

Yes, the 1/2in reduced shank is designed to fit a standard 1/2in drill chuck, allowing the 53/64in bit to be used in drills that cannot accept a full-size shank.

What is the correct way to install this Silver and Deming bit so it does not slip?

Open the chuck jaws wide, insert the 1/2in reduced shank fully until the flute begins, then tighten securely on the flat shank surfaces — not on the flutes — to prevent spin-out.
