High-grade titanium-coated twist drill grinding / drilling high hardness steel, iron, cast iron, aluminum alloy with high hardness of metallic materials

Directional grinding/precision / ultra wear-resistant (factory outlet)

Product introduction:

1.材料：钻头使用9341高速钢制造， Head opening of 118 degrees, cleaning polishing processing technology for the rolling, rather than the more precise drill positioning when using bit runout smaller

2. 钻头硬度为 HRC63-67 ，高硬度，切削非常快捷、轻松

3. drill the surface treated by Ti, rust-proof effect

4. drill through a special heat treatment and high temperature quenching and tempering three times, bits of Red hardness, abrasion resistance increase and ensure the drill working at high speed without annealing

5. the products undergo a rigorous examination in line with Germany D388 standard, exported to Europe, America, Canada, Australia and other regions, Machining industry
