Cobalt Drill Bits
|Cobalt drill bits are designed to cut through extremely hard metals, including stainless steel, with up to twelve times the lifespan when compared with an average 118° point HSS drill bit. No center punch is needed—the 135° Quick-Cut points are self-centering and penetrate quickly with less pressure. Will not ´´walk´´ or ´´wander.´´ Extremely heat resistant; must be used and operated at 1500 RPM or greater for maximum efficiency.
