Cobalt Drill Bits description from Rockler
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 118Adeg point HSS drill bit. No center punch is needed-the 135Adeg 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.
I ordered Cobalt Drill Bits and looks better than on images.
