37/64in HSS Reduced Shank Drill Bit

The Drill America D/ARSD3/8X37/64 is a high-speed steel drill bit with a reduced 3/8in shank designed for Silver and Deming applications. Surface treated flutes improve chip evacuation and extend tool life when drilling through steel and other ferrous materials. It suits machinists and maintenance technicians who need a single large-diameter hole without changing to a larger chuck capacity.

Thermals noise and power draw in normal use

Heat generation depends on the host machine spindle speed feed rate and workpiece material rather than the bit itself. The accessory produces no electrical noise and draws no power independently. Cutting temperature is managed by the operator through coolant choice and cutting parameters applied at the drill press or milling machine.

Questions about this item

How do I install the 3/8in shank into my drill chuck, and what step do people get wrong?

Open the chuck jaws wide, insert the 3/8in shank fully so the jaws grip the shank body not the flutes, then tighten securely; the common error is clamping on the fluted section which causes slippage.

When will the 37/64in HSS bit need replacement?

Replace the bit when the cutting edges become dull or chipped, which shows as slower feed, excess heat, or rough holes in steel; resharpening can extend life but the reduced shank diameter limits how many times this can be done.
