Description:

SIZE: Cutting edge diameter: 15/16 inch (23.813mm), shank diameter: 1/2 inch, flute length: 77mm/3.03 inch, total length: 150mm/5.91 inch, package content: 1 Pcs x Reduced Shank Drill Bit. MATERIAL: The drill bit is made of M2 high-speed steel material, it has high hardness and wear resistance, suitable for processing medium-high hardness metal. The Nitriding Black finish enhances the corrosion resistance and wear resistance of the drill bits, effectively extending drill bit's service life.. 135-DEGREE SPLIT-POINT TIP: Provides excellent processing stability, is suitable for harder materials, and can effectively reduce the risk of cutting-edge chipping, improving drilling efficiency and hole quality.. WIDE APPLICATIONS: 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..
