Description:

SIZE: Cutting edge diameter: 16mm, shank diameter: 12mm, cutting edge length: 3 inches, small and easy to carry, suitable for various material. Package Content: 1Pcs x Reduced Shank Drill Bit. MATERIAL: The drill bits are made from M35 high-speed steel, which contains 5% cobalt, resulting in higher hardness. M35 high-speed steel drills provide exceptional abrasion resistance, making them highly effective for machining high-hardness materials and metals. The nitrided black surface treatment enhances the corrosion resistance and wear resistance of the drill bits, effectively extending their service life.. 118-DEGREE SPLIT-POINT TIP: Conventional Point, not easy to slide, suitable for wood, plastic soft metal, and other materials drilling, widely used in daily operation, more appropriate for home and light industry use, simple operation, strong adaptability.. WIDE APPLICATIONS: The drills exhibit excellent red hardness and wear resistance, making them suitable for high-hardness materials such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloys, and cast iron. They are also effective for use with plastics and wood.. TIP: When using a large drill bit, its best to start by drilling smaller holes. This makes it easier to create larger holes accurately, select the appropriate coolant when running at high speeds when using hss drills to prevent tool overheating and wear..
