Drill bit for 47/64 inch holes

This Drill America Silver and Deming drill bit cuts a 47/64 inch diameter hole, equivalent to .7344 decimal inches. The high-speed steel construction suits general-purpose drilling in metal, wood and plastic. A 1/2 inch reduced shank with three flats fits standard drill chucks and prevents slipping under torque. The bit is new and ready for workshop or job-site use.

Sustained cutting with surface-treated flutes

Surface-treated flutes reduce friction and improve chip evacuation during continuous drilling cycles. The 3 inch flute length and 6 inch overall length allow deeper holes without frequent withdrawal. High-speed steel retains hardness when the tip temperature rises during prolonged cuts. The three-flatted shank maintains grip even when the drill motor runs at full load for extended periods.

Questions about this item

How much heat does the 47/64" HSS Silver & Deming bit generate during continuous drilling?

High-speed steel dissipates heat well, and the surface-treated flutes help clear chips quickly, reducing friction buildup during extended use in metal or wood.

What shank size must my drill chuck accept to hold the 1/2" reduced shank on this bit?

The bit has a 1/2" reduced shank with three flats, so your drill chuck must open to at least 1/2" to grip it securely.
