Kennametal 6191557 Milling Insert KCPM40 Solid Carbide

Product Description

The KENNAMETAL 6191557 is a solid carbide milling insert with ISO code XELT160516ERD41 and ANSI code XEPT160516ERD41, designed for high-performance metal removal in demanding milling applications. This single-sided, square-shaped insert features a 90-degree included angle and carries a dual PVD coating of TiAlN and AlCrN for thermal resistance and edge durability. It measures 21/32 inches in length, 7/32 inches thick, with a 1/16-inch corner radius and a maximum depth of cut of 0.326 inches. Screw-held and right-hand oriented, it is installed by machinists and tooling specialists in production milling environments.

This insert is suited for milling steel, stainless steel, superalloys, and titanium, corresponding to ISO material codes P, M, and S. The positive rake geometry and D41 chip breaker promote efficient chip evacuation and reduced cutting forces across these material groups. The honed cutting edge style provides edge stability under interrupted cuts and varying feed conditions. It is compatible with the Kennametal 7792VXE16 cutter series and is appropriate for both roughing and semi-finishing passes depending on feed and depth parameters.
