HSS-PM Cobalt Drill Bits | Powder Metallurgy Superalloy | For Stainless Steel & Hard Metal

The ExactBit HSS-PM Cobalt drill bit leverages advanced powder metallurgy to deliver exceptional performance in the toughest materials. Its superior heat and wear resistance allows for faster drilling speeds and longer life in stainless steel, alloy steel, and other superalloys. Features and Benefits - HSS-PM with 5% Cobalt - Powder metallurgy construction with high cobalt content provides extreme hardness and red-hardness for drilling hardened metals. - Superalloy Formulation - Specifically engineered to maintain a sharp cutting edge under high-temperature conditions, preventing premature dulling. - Optimized 135° Split Point - Ensures precise starting, reduces walking, and requires less downward pressure for efficient penetration. - Premium Surface Finish - Minimizes friction and chip adhesion, promoting smoother drilling and easier chip ejection. Applications - Professional fabrication and machining of stainless steel (SUS) components and fixtures. - Drilling into high-strength alloy steels and cast iron in automotive and aerospace workshops. - Industrial maintenance requiring reliable penetration of hardened or abrasive metal surfaces.
