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.
