√FEATURE:
M35 high-speed steel drill bits, containing 4.50% to 5.50% cobalt, has high hardness. These bits are recognized for their exceptional wear resistance, impressive heat resistance, and high crack resistance, making them suitable for machining high-hardness metals.
The drill bit surface features a vacuum titanium coating that forms a hard, smooth finish. It boasts excellent lubricity, reducing friction, resistance and chip adhesion for smooth, effortless chip removal. It is also corrosion-resistant, rust-proof and wear-resistant, effectively extending service life.
The 135-degree split point tip drill provides excellent processing stability and is well-suited for harder materials. It effectively reduces the risk of cutting-edge chipping, thereby improving drilling efficiency and hole quality.
The hexagonal shank design maximizes clamping contact area, ensuring a firm, slip-free and wobble-resistant grip for stable, precise drilling. It also delivers higher torque output, easily handling the heavy-load demands of drilling high-hardness materials.
√APPLICATION:
The 5% cobalt high-speed steel drill bits are specifically designed for cutting hard metal, such as steel, alloy cast iron, stainless steel, iron, copper, aluminum alloy, and cast iron. They are also effective in plastics and wood.
√PACKING LIST:
