Kennametal 4111084 Cutoff Insert KCU25 Carbide 2.2mm

Product Description

The KENNAMETAL 4111084 is a single-end carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries a 2.2 mm (0.0866 inch) cutting width and a neutral lead angle with 0 degrees of lead, making it suitable for straight, symmetric cutoff passes without directional bias. The insert uses a PVD-applied AlTiN coating over a KCU25 carbide grade substrate, which provides thermal resistance and edge wear protection during interrupted cuts and continuous bar stock parting. It is held in place by a clamp-style toolholder and is intended for use by machinists and toolroom technicians in production turning environments.

This insert is part of the A2 series and is designated by the style code A2022N00CM02. It is suited for parting and grooving applications on ferrous and non-ferrous workpieces in both manual and CNC turning setups. The CM chipbreaker geometry assists with chip control during cutoff operations where chip evacuation is critical to tool life and surface finish. Typical applications include production shops, job shops, and maintenance machining environments where consistent cutoff performance is required across medium to high run quantities.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine fully powered down and the spindle locked before changing inserts. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer to seat the insert securely without over-tightening the clamp. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Follow all applicable shop safety protocols and machine guarding requirements when returning the machine to service.
