21/32″ HSS Silver and Deming Drill Bit

This high-speed steel Silver and Deming bit has a 21/32″ cutting diameter and a 1/2″ reduced shank with three flats for a secure grip in a drill chuck. It is suited for general-purpose drilling in metal, wood and plastic where a larger hole is required but the drill only accepts a 1/2″ shank. The surface-treated flutes help clear chips during use.

Check shank capacity and flute reach before ordering

Verify that your drill chuck opens to at least 1/2″ to accept the reduced shank and that the three-flat design is compatible with your chuck type. The flute length is 3″ and the overall length is 6″, so ensure the workpiece thickness and drill travel can accommodate that reach. This bit is not for machines that require a full-size shank matching the cutting diameter.

Questions about this item

Does the Drill America 21/32in bit include any extra accessories or just the bit itself?

The box contains only the single Silver and Deming drill bit with its 1/2 reduced shank and three-flatted surface-treated flutes. No pilot drills, cases or lubricants are supplied.

Should I pick the 21/32in .6563 decimal size or a different diameter for my 1/2in chuck?

Choose this 21/32in bit when the hole must be exactly .6563 decimal; the 1/2 reduced shank fits any standard 1/2in chuck, while other diameters in the same series keep the same shank but change the cutting size.
