1-3/16" Drill Bit 1/2" Reduced Shank 3-Flat M35 5% Cobalt High-Speed Steel Twist Black and Gold Finish 135° Bits for Hard Metal Stainless Steel,1pcs

Key Features

• SIZE Cutting edge diameter 1-3/16 inch (30.163mm), shank diameter 1/2 inch, flute length 78.74mm/3.1 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 Black and Gold 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, 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.
