Drill America Cobalt Silver Deming Bit
The Drill America 1-1/16in cobalt steel drill bit features a 1/2in reduced shank for use with standard drill chucks. Bronze oxide surface treatment on the flutes helps resist wear during heavy-duty drilling tasks. It is built for demanding metalworking applications.
Suited for large-hole metal drilling.
This bit suits machinists and maintenance technicians who need a single tool to bore 1.0625in diameter holes in tough alloys. The 3in flute length and 6in overall length limit its use to through-holes within that depth range. Buyers needing smaller diameters or deeper reach should consider other options.

Questions about this item
How do I install the 1/2in reduced shank into my drill chuck without it slipping?
Open the chuck wide enough for the 1/2in shank, insert the bit fully so the flutes clear the jaws, then tighten securely; the reduced shank fits standard 1/2in chucks.
When will the cobalt steel cutting edges need resharpening or replacement?
Resharpen when drilling 1-1/16in holes becomes slow or produces excessive heat; cobalt steel holds an edge longer than high-speed steel, extending service intervals.
