Kennametal 2455854 Milling Insert OFKT06L5AFENGB KC520M

Product Description

The KENNAMETAL 2455854 is a solid carbide milling insert in the OFKT series, designed for face milling and shoulder milling operations in metalworking applications. Identified by ISO code OFKT06L5AFENGB and ANSI code OFKT53AFEN4GB, this insert features an octagon shape with 8 cutting edges, a TiAlN coating applied via PVD process, and a KC520M manufacturer grade. The insert carries a positive rake angle of 5 degrees and a relief angle of 25 degrees, with a honed cutting edge style and GB chip breaker geometry. It is held in place by screw clamping and is rated for a maximum depth of cut of 0.2360 inches. Primary application is cast iron machining, material grade group K.

This insert is suited for milling cast iron workpieces in industrial machining environments, typically on CNC milling machines and machining centers. The OFKT series geometry with positive rake reduces cutting forces, which is beneficial when working with brittle or abrasive cast iron grades. The GB chip breaker assists with chip control during medium to roughing passes. Compatible with the KSOM cutter series, this insert is installed and serviced by machinists and tool-and-die professionals in production shop environments.

Installation Notes

Insert installation and replacement should be performed by a qualified machinist with the machine spindle fully stopped and locked out per applicable machine safety procedures. Use the appropriate torx or hex key to torque the clamping screw per the toolholder manufacturer specification. Inspect the insert seat and clamping screw for wear or debris before seating a new insert. Do not exceed the maximum depth of cut rating for this insert geometry.
