Century Drill & Tool Cobalt Drill Bit Sets & Pro Grade Cobalt Drill Bit Sets

Thank you for shopping with us!

Made from M35 steel with 5% cobalt, Century’s Cobalt drill bits are designed to cut through extremely hard metals, including stainless steel.
No center punch needed: Century 135-degree quick-cut points are self-centering and penetrate faster with less pressure…will not “walk” or “wander” at the starting surface.
Extremely heat resistant, must be used and operated in power units that have a RPM speed of 1,500 or more for maximum efficiency.

Use with Cutting Oil when drilling metal.
