Universal Endmills-High-performance Type/Basic Type/Economical Type
Application Variety
Features--of HTA Series High-performance Endmills:
□ Carefully selected High-strength carbide and coating cemented carbide, improve the oxidation resistance, heat resistance, wear resistance.
□ Fewer macroparticles on film surface result in improved smoothness. Reduced abrasion and better deposition resistance improved wear and adhesion resistance.
□ Unique geometry improves chip removal and tools rigidity. So the tools can machine≤HRC55 following materials: stainless steel, heat-resistant alloys, titanium, nickel alloys, cast iron, copper alloys, etc.
□ High performance carbide material ensure longer tool life and high efficiency.
Features--of STA Series Basic Type Endmills:
□ Carefully selected High-strength carbide and coating cemented carbide, improve the oxidation resistance, heat resistance, wear resistance.
□ Superior chipping, wear resistance，and better surface roughness from special cutting edge and margin shape .
□ Aplly to very wide work materials.
□ STA：economical and high performance carbide meterial.
Features--of ST Series Economical Type Endmills:
□ Better heat and wear resistance from ST coating for a long life.
□ Aplly to very wide work materials.
□ Superior chipping, wear resistance，and better surface roughness from special cutting edge and margin shape .
□ Economical and high performance carbide material.
