Frequently Asked Questions

T02025 refers to a chamfered cutting edge: a 0.20 mm chamfer at 25° angle. This edge prep helps protect the cutting edge, prevent chip-edge breakdown, and maintain stable performance in semi-finishing and finishing cuts.

This insert performs best on steels, alloyed steels, and cast irons in finishing and semi-finishing operations where temperature stability and wear resistance are important.

The corner radius is 0.8 mm (0.8 R), providing a good balance of strength and fineness in finish.

A65 is a proven Kyocera grade combining optimized carbide substrate and advanced coatings (CVD / PVD) to improve oxidation resistance, edge toughness, and resistance to crater wear at high cutting temperatures.

No — VNGA160408T02025 is a turning insert (external turning). It is not intended for milling or drilling operations.
