Mitsubishi Materials MGMN300-M Carbide Turning Insert

Description:

The MGMN300-M Carbide Turning Insert is used in CNC lathes and turning centers to perform grooving, parting-off, and profiling operations on steel, stainless steel, cast iron, and non-ferrous materials. Commonly installed in external grooving holders, internal grooving bars, and cutoff tools used in machine shops and production machining environments. Machinists, maintenance teams, and CNC programmers use this insert for production turning, precision grooving, and replacement of worn cutting edges. The insert is specifically designed for use with MGEHR2020-3 and MGIVR2020-3 tool holders.

Applications:

The MGMN300-M carbide turning insert is commonly used in CNC lathes, manual engine lathes, screw machines, and production turning centers where 3 mm grooving and cutoff operations are required. The double-ended insert design provides two usable cutting edges for improved economy and longer service life. The medium chipbreaker geometry allows machining of carbon steel, alloy steel, stainless steel, and cast iron in both continuous and interrupted cuts.
