35/64in HSS Reduced Shank Drill Bit

This Drill America Silver and Deming drill bit is manufactured from high-speed steel with a 1/2in reduced shank for use in larger drill chucks. It suits machinists and maintenance technicians who need a 35/64in hole in metal or wood. The surface-treated flutes aid chip evacuation during drilling operations.

Surface-treated flutes and reduced shank

The surface-treated flutes reduce friction and improve chip flow compared with untreated flutes. The 1/2in reduced shank allows the bit to fit standard 1/2in chucks despite the larger cutting diameter. These features extend bit life and broaden machine compatibility for the operator.

Questions about this item

How often will the HSS cutting edges need resharpening when drilling steel?

Resharpen when the bit starts to push instead of cutting; the 35/64" high-speed steel flutes can be reground several times before the reduced shank diameter limits further work.

What stops continuous drilling before the bit wears out?

The 3" flute length limits chip clearance, so heat builds up first during sustained cuts; withdraw frequently to clear swarf and cool the 0.5469" diameter cutting zone.
