SIZE: Cutting edge diameter: 16.5mm, shank diameter: 12mm, flute length: 76.2mm/3 inch, total length: 152.4mm/6 inch, 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, making them highly effective for machining high-hardness materials and metals. The Nitriding Black finish enhances the corrosion resistance and wear resistance of the drill bits, effectively extending drill bit's service life.
118-DEGREE SPLIT-POINT TIP: The 118° Angle design has a high cutting efficiency, which may mean less effort for the operator. The 118° Angle is the traditional standard Angle, suitable for conventional metal processing and has a wide range of applications
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, it's 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.
