Product description
- 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.
- 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 their 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.
- TIP When using M35 cobalt drill bits, it is important to choose the appropriate cutting fluid to prevent tool overheating and wear. Additionally, due to the higher hardness of the drill bits, it is necessary to apply greater cutting forces and higher cutting speeds to ensure the tool's lifespan and machining quality.
