Tungsten steel bit is multi-layer nano-coated bit suitable for engraving hard metals.

The introduction of nano-materials into the coating can significantly improve the high temperature resistance and oxidation resistance of the material. Adding nano-phases can further improve the hardness and wear resistance of the coating, and maintain high toughness to achieve the effect of reducing the friction coefficient.

Selected materials High quality tungsten steel

The fourth-generation anti-corrosion cemented carbide has a grain size as low as 0.5um. When the material encounters external erosion, an anti-corrosion protective layer is formed on the surface to resist corrosion and greatly improve the service life of the tool.

Sand blasting passivation treatment is more durable

A passivation film with dense performance and good coverage is formed on the surface, and at the same time, it will remove all kinds of dirt, increased resistance to oxidation prolongs tool life.

The effect of passivation treatment: Form a passivation film and remove all kinds of dirt at the same time, increase the oxidation resistance and prolong the service life of the tool

This drill bit is not suitable for aluminum, it is

Suitable for:  Ordinary steel, carbon steel, alloy steel, pre-hardened steel, quenched and tempered steel, die steel, high hardness steel (45-55°), stainless steel, copper alloy (not suitable for aluminum)
