Cobalt Drill Bits

Cobalt Drill Bits

• 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’s 135° quick-cut points are self-centering and penetrate faster with less pressure. Drill bit will not “walk” or “wander” at the starting point.
• Extremely heat resistant, must be used and operated in power units that have a RPM speed of 1,500 or more for maximum efficiency.
