Nano-Coated Tungsten Steel Bit for Hard Metal Engraving
Crafted from premium tungsten steel, this multi-layer nano-coated bit is specially designed for precise engraving on hard metals.

Advanced Nano Coating Technology
The integration of nano-materials enhances high-temperature stability and oxidation resistance. Nano-phase reinforcement further increases hardness and wear resistance while maintaining excellent toughness, effectively reducing friction during operation.

Premium Tungsten Steel Construction
Made from high-quality tungsten steel, featuring fourth-generation anti-corrosion cemented carbide with an ultra-fine grain size of up to 0.5 μm. When exposed to harsh conditions, the material forms a protective anti-corrosion layer on the surface, significantly extending tool lifespan.

Sandblasted Passivation Treatment for Enhanced Durability
The surface undergoes sandblasting and passivation to create a dense, well-covered protective film. This treatment removes impurities, improves oxidation resistance, and increases overall durability.

Longer Service Life & Reliable Performance
The combined anti-corrosion layer and passivation film provide superior resistance to wear, heat, and oxidation, ensuring consistent performance and extended tool life.

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) 

Package Includes: 1xCNC Bit
