M42 8% Cobalt high-speed steel is formulated with a high cobalt and molybdenum-vanadium alloy, offering superior toughness, hardness, and wear resistance. It optimally balances high-temperature hardness, wear resistance, and durability.Titanium Nitride (TiN) Coated: Enhances twist drill performance by increasing hardness, reducing friction, improving oxidation resistance, and preventing material adhesion. This coating significantly improves drill bits' lifespan, machining efficiency135-degree split point tip design:The drill bit's 135-degree angle enhances stability and precision when drilling hard materials. This design improves heat dissipation and tool durability, making it suitable for hardened steel, cast iron, and other tough alloys.√APPLICATIONThe M42 HSS titanium coated twist drill is engineered for high-hardness, high-viscosity, and high-temperature materials due to its exceptional red hardness, wear resistance, and anti-adhesion properties. It is suitable for drilling: High-temperature alloys, Titanium alloys, Stainless steel, Hardened steel, Cast iron, Hard plastics, and Wood√PACKING LIST:-Flute Diameter: 10mm/0.39 inch ≈ 25/64inch-Shank Diameter: 10mm-Flute Length: 87mm/3.43 inch-Total Length: 133mm/5.24 inch-Package Content: 4pcs x Drill Bit√NOTE:During the machining process, friction between the drill bit and the material generates significant heat. Using coolant effectively reduces the temperature, preventing tool overheating and extending the lifespan of the drill bits.
