Drill America 63/64in HSS Silver

This Drill America drill bit is a 63/64in high-speed steel Silver and Deming bit built for heavy-duty drilling in metal and wood. It features a 1/2in reduced shank with three flatted surfaces that lock securely into a standard drill chuck. The surface-treated flutes improve chip evacuation and reduce friction during extended use. It suits professional mechanics and fabricators who need a large-diameter hole without a specialised chuck.

Replacing smaller bits or worn S&D tooling

This bit replaces smaller twist drills when a 63/64in hole is required and upgrades worn Silver and Deming tooling that no longer cuts cleanly. The jump is worth it when the job demands a single-pass hole at this exact diameter and the reduced shank matches the existing 1/2in chuck capacity. It is not for buyers who need a different decimal size or a bit that fits a larger chuck without an adapter.

Questions about this item

Will the 1/2 inch reduced shank with three flats fit my drill chuck?

Yes, the 1/2 inch reduced shank with three flats is designed to fit standard 1/2 inch drill chucks securely.

How do I install the bit so the three flats grip properly, and what step is often missed?

Insert the shank fully, align the three flats with the chuck jaws, and tighten each jaw evenly; the missed step is failing to seat the shank completely before tightening.
