Kennametal 3957214 Milling Insert KCPM20 Solid Carbide

Product Description

The KENNAMETAL 3957214 is a solid carbide milling insert carrying ISO designation EDCT140408PDERGD and manufacturer grade KCPM20. It is a parallelogram-style insert in the EDCT series, designed for use in indexable milling cutters on machining centers and milling machines. The insert features a multilayer CVD coating stack of TiN, TiCN, and Al2O3 applied via MTCVD process, providing wear resistance and thermal stability across a wide range of workpiece materials. With a positive rake angle of 15 degrees, a honed cutting edge, and a GD chip breaker geometry, it is suited for stable, productive cuts. Machinists and tool-room technicians install and index these inserts during scheduled tooling changeovers.

This insert is intended for machining steel, stainless steel, cast iron, and hard materials, covering ISO material application codes P, M, K, and H. It is compatible with the Mill 1-14 cutter series. The right-hand configuration and screw-holding method make it a straightforward index in standard EDCT-style milling bodies. It is a single-sided insert offering 2 cutting edges per insert.

Installation Notes

Installation and indexing of milling inserts should be performed by a qualified machinist or tooling technician. Ensure the milling spindle is fully stopped and the machine is locked out before accessing the cutter body. Use the correct torx or hex key driver specified by the cutter body manufacturer when tightening the clamping screw — do not overtighten or undertighten the screw, as either condition can lead to insert movement or breakage during a cut. Inspect the insert seat and clamping screw for wear or debris before seating a new insert.
