GY2M0300F020N-MS NX2525
Mitsubishi Materials | Premium Cermet Grooving Series
The Mitsubishi GY2M0300F020N-MS NX2525 is a high-performance 3.0mm width grooving insert designed for the modular GY Series tool system. Unlike standard carbide, this insert utilizes the NX2525 Cermet grade, which provides exceptional chemical stability and oxidation resistance. Combined with the MS chipbreaker (Medium-Low Feed), it is the ultimate solution for achieving a mirror-like surface finish in steel and carbon steel applications.

NX2525 Cermet Grade
The NX2525 grade is a cermet (Ceramic + Metal) material that offers superior resistance to built-up edge (BUE). Because cermet does not have a high affinity for steel, it produces significantly better surface gloss and dimensional accuracy than coated carbide in finishing operations.
MS Chipbreaker Advantage
The MS (Medium-Low Feed) chipbreaker is specifically tuned for precision profiling and grooving. It facilitates smooth chip breaking even at low feed rates, preventing long tangles that can damage the workpiece surface finish during high-speed finishing.
