An optimal CVD grade for high speed machining of cast iron

The thickest coating layer improves tool life in high speed machining

Applications & Features

External groovingInternal turningExternal turning

1. Grade feature

T505’s coating thickness is 1.5 times thicker than conventional grades.

The thickest coating layer of all Tungaloy’s CVD grades ever

– Thickest coating layer of all Tungaloy’s grades
– Al2O3 coating with strengthened wear resistance
– TiCN layer with high carbon content
– New substrate with high thermal conductivity

T515

2. Application range

– Complementary grade to T515
– High wear resistance
– The best grade for high speed machining of K05 – K20
