SEMX1204AFTN-ME12 F40M Insert R217/220.53 Face Milling Cutter (S/S & Steel)

The SEMX1204AFTN-ME12 F40M is a single-sided PVD-coated carbide milling insert designed for Quattromill face milling cutters. Featuring the ME12 cutting geometry, this insert combines four indexable cutting edges with a positive cutting design to support efficient face milling operations. The insert has a 12.70 mm inscribed circle, 12.70 mm cutting-edge length, 8.70 mm effective cutting-edge length, 4.76 mm thickness, and a 1.12 mm corner radius. A 1.5 mm wiper edge is incorporated into the design to assist in producing improved surface finishes during milling applications. The F40M grade is a PVD-coated carbide grade supplied within the Quattromill platform. Combined with the ME12 geometry, the insert is intended for use in compatible Quattromill face milling cutters where a four-edge insert design is required. The insert features a 20° clearance angle and approximately 21° rake angle, helping create a positive cutting action within the cutter system. The available technical information does not explicitly define material-group suitability or whether this exact insert is intended for continuous, interrupted, or mixed cutting conditions, so those claims have been intentionally excluded.
