Drill America 37/64" Cobalt Drill Bit
The Drill America 37/64" drill bit features a reduced shank design that fits 1/2" chucks while delivering a larger cutting diameter. Its cobalt steel construction provides high heat resistance for drilling tough alloys and stainless steel. The bronze oxide surface treatment reduces friction and enhances chip evacuation through the treated flutes. This Silver and Deming style bit suits maintenance technicians and metal fabricators requiring precision holes in hard materials.
Sustained drilling performance
Under continuous load the cobalt substrate maintains cutting hardness at elevated temperatures where standard high-speed steel would soften. The oxide coating resists galling and welding during deep-hole drilling up to the 3" flute length. Reduced shank rigidity limits deflection in stationary drill presses better than in handheld tools. Operators needing extended tool life in production runs should consider dedicated coolant-fed tooling instead.

Questions about this item
How much heat does the 37/64in cobalt bit generate during extended drilling in steel?
Cobalt steel dissipates heat better than standard high-speed steel, and the bronze oxide finish reduces friction, keeping the 37/64in bit cooler during long drilling sessions.
What chuck size is required to hold the 1/2in reduced shank on this drill bit?
A 1/2in or larger drill chuck is needed to secure the reduced shank of this 37/64in cobalt Silver and Deming drill bit.
