Cermet Grade T2500A

Presenting a new cermet grade for steel grooving and turning

Greatly improves toughnes through a dense and uniform structure

for stability and longer tool life.

Uses a new cutting edge treatment method to maintain a good

glossy surface finish from the beginning and over a long period

of time.
