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.

| Material Grade | NX2525 (High-Performance Cermet) |
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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
