7.5Mm Drill Bit Straight Shank M35 5% Cobalt Hss For Metal Steel - 2 Pack

FEATURE:M35 high-speed steel drill bits, containing 4.50% to 5.50% cobalt, has high hardness. These bits are recognized for their exceptional wear resistance, impressive heat resistance, and high crack resistance, making them suitable for machining high-hardness metals.Gold Finish can be used to improve the surface properties of drill bits' materials and increase their wear resistance and corrosion resistance, thus extending the service life of the drill bit and working efficiencyThe 135-degree split point tip drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality. APPLICATION:The 5% cobalt high-speed steel drill bits are specifically designed for cutting hard metal, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood. PACKING LIST:-Cutting Edge Diameter: 7.5mm-Shank Diameter: 7.5mm-Flute Length: 69mm/2.72inch-Total Length: 109mm/4.29inch-Package Content: 2pcs x Drill Bit NOTE:Applicable coolant, during the machining process, friction between the drill bit and the material generates a significant amount of heat, coolant can effectively reduce the temperature, preventing the tool from overheating, and extending the drill bit lifespan.
