uxcell 15.5mm Drill Bit 12mm Reduced Shank M35 Cobalt High-Speed Steel Twist Nitriding Black Surface 118° Drill for Steel Alloy Cast Iron High Hardness Materials

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 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.
