Engineered For Hard Metal Drilling Performance: Made from M35 steel with 5% cobalt, these drill bits are built to cut through stainless steel, hardened metals, and high-tensile alloys with strength, durability, and long tool life 135° Quick-Cut Points For Precise, Effortless Starts: Precision-ground tips are self-centering and require less pressure to penetrate, eliminating the need for a center punch and preventing walking or wandering at the starting point High Heat Resistance For Demanding Applications: Designed to maintain hardness and cutting edge under high temperatures, delivering consistent performance when used with power tools operating at 1,500 RPM or higher Consistent Performance In Tough Materials: Ideal for metalworking, fabrication, and repair applications where accuracy, efficiency, and durability are required across repeated use Pro Pack Of 6 For Added Value And Convenience: Includes 6 cobalt drill bits, providing extra coverage for ongoing projects and reducing downtime when working through tough materials These cobalt drill bits are designed for high-performance drilling in tough metal applications. Made from M35 steel with 5% cobalt, they deliver the strength and durability needed to cut through stainless steel, hardened metals, and other high-tensile materials. Each bit features a 135° quick-cut point that is self-centering and requires less pressure to start drilling. This design helps eliminate the need for a center punch while reducing walking at the starting point. Built to perform under demanding conditions, these bits maintain their hardness and cutting edge even at high temperatures when used with power tools operating at 1,500 RPM or higher. Ideal for professionals and DIY users, this set provides reliable performance across metalworking, fabrication, and repair applications. The included 6-piece pack ensures you have the extra coverage needed for repeated use in tough materials.
