63/64" Cobalt Drill Bit with Reduced Shank
This cobalt steel drill bit features a 63/64 inch diameter and a 1/2 inch reduced shank for use with standard chucks. The bronze oxide surface treatment on the flutes enhances wear resistance and chip evacuation. It is built for drilling tough materials such as stainless steel and high-strength alloys where standard high-speed steel wears quickly. Machinists and maintenance technicians gain a durable option for heavy-duty metalworking tasks.
3-Inch Flute Length for Deep Holes
The flute length of 3 inches provides ample reach for deeper drilling operations while the 6-inch overall length ensures rigidity. Cobalt construction maintains hardness at elevated temperatures, allowing sustained cutting speeds in abrasive alloys. The reduced shank limits compatibility to chucks accommodating 1/2 inch or larger, so it is not suited for smaller drill presses or hand drills with tighter capacity. Users needing larger diameters or longer reach must select a different bit.

Questions about this item
Will the 1/2in reduced shank fit the chuck on my older 1/2in drill press?
Yes, the 1/2in reduced shank is designed to fit standard 1/2in drill chucks, so it will work with your existing drill press.
How can I verify the bit is cutting correctly once I start drilling?
The cobalt steel and bronze oxide coating should produce clean, consistent chips and maintain a steady feed rate without excessive heat buildup.
