Products Function
1.HRC: HRC45 HRC55 HRC58 HRC60 HRC65
2.Coated: AlTiN, TiAlN, TiAISI,TiSiN, TiN, DLC,Nano, Diamond
3.Could be used for the processing of copper, cast iron, carbon steel, mould steel, stainless steel, titanium alloy, tool steel, and heat-treated steel
Products Features
1. Special Cutting Edge: Special cutting edge can increase the cutting ability. The lifetime of tools and machines will be longer.
2. Smooth and Wide Flute: Smooth and wide flute will remove the cuttings more easily.
3. Heat-resistant Coating: With highly heat-resistant HELICA coating, can be used for high-speed processing.
4. Bronze Coating: Under bronze coating, any abrasion is easy to be recognized.
5. High Quality Raw Material: The raw material is used of high toughness, grain-sized carbon tungsten.
6. Polished Surface Treatment: With high polished surface treatment, reduce the friction coefficient could be reduced, the lathe efficiency could be improved, more production time could be saved.
