Drill America 1-3/16in Cobalt Drill Bit
This Drill America cobalt steel bit features a 1-3/16 inch cutting diameter with a decimal equivalent of 1.1875. It has a reduced 1/2 inch shank designed for use in chucks that cannot accommodate larger shanks. The bronze oxide surface treatment on the flutes helps resist wear during demanding drilling tasks. Overall length measures 6 inches with a 3 inch flute length.
Suited for large hole drilling in tough materials
This bit suits machinists and maintenance technicians drilling large diameter holes in stainless steel, cast iron or other high tensile alloys where cobalt heat resistance is required. The reduced shank allows compatibility with standard 1/2 inch capacity drill chucks. Buyers needing a full 1-3/16 inch shank for maximum rigidity or those requiring a pilot drill for deep hole accuracy should look at alternative tooling.

Questions about this item
Will this 1-3/16" cobalt drill bit fit the 1/2" chuck on my current drill press?
Yes, the reduced shank is sized to 1/2" so it fits standard 1/2" drill-press chucks and large portable drills.
Can I use this bit at the same 1.1875" diameter in a handheld cordless drill?
The 1-3/16" diameter requires high torque; a handheld cordless drill may stall or overheat unless it delivers sufficient power and you use a side handle for control.
