Kennametal 5533151 Cutoff Insert 2mm Carbide KCU25

Product Description

The KENNAMETAL 5533151 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. Manufactured under the Beyond Evolution series, it carries the KCU25 grade with a CVD-applied TiOCN coating that provides wear resistance and thermal stability during interrupted or continuous cuts. The insert features a 2 mm cutting width, a 6-degree lead angle with neutral hand orientation, and a right-hand configuration. A 2-degree relief angle reduces rubbing on the workpiece, while the CF chipbreaker geometry promotes controlled chip evacuation in medium-duty cutoff applications. Machinists and CNC operators working in production environments are the primary users of this insert.

This insert is suited for cutoff and grooving operations on ferrous and non-ferrous workpiece materials in residential shop, job shop, and production turning environments. It is a single-end insert with an EC-U style interface and an insert seat size of 2, making it compatible with toolholders designed around that seat specification. The Beyond Evolution series targets applications where consistent tool life and chip control are priorities. No multi-use capability is specified for this insert; it is dedicated to cut-off operations.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine before seating or removing any insert. Use appropriate torx or hex keys to the toolholder manufacturer torque specification when securing the insert clamp. Inspect the insert pocket and clamping surfaces for debris or damage before seating a new insert to ensure accurate positioning and safe operation.
