41/64" Cobalt Drill Bit for Heavy Duty Drilling
The Drill America bit is made from cobalt steel with a bronze oxide surface treatment. It features a 1/2 inch reduced shank designed to fit standard drill chucks. The flute length is 3 inches and the overall length is 6 inches. This accessory targets professionals needing durable performance in tough materials.
Suited for metalworkers drilling large diameter
The reduced shank allows use with 1/2 inch capacity drills without requiring a larger chuck. Buyers who need a full 41/64 inch shank or a different flute geometry should look at other options. Those requiring a complete drill bit set or smaller incremental sizes will not find them here. This single bit addresses a specific large-hole requirement.
