General description Faithfull Cobalt Quick-Change Impact Drill Bits feature a revolutionary tip design that is superior to any other drill bit in the industry. These innovative drill bits have 7 cutting edges and 3 peaks, providing several distinct advantages: super-accurate self-centering, speed that is twice as fast as split point drill bits, and a tool lifetime that can be up to 10 times longer in mild steel. Manufactured from M35 HSSE grade steel with a 5% cobalt content, these bits offer excellent heat resistance and cutting performance, leaving much less burr than other drill bits. The protruding center tip acts like a pilot drill, enabling precise positioning and preventing the drill from wandering. These bits are impact rated and have a 1/4-inch quick-change shank for use in impact drivers, making them ideal for heavy-duty industrial work in various tough materials. Technical specifications Tip Diameter: 4.0mm Working Length: 43mm Overall Length: 91mm Material: M35 HSSE steel
