Kennametal 5533156 Cutoff Insert 2mm Neutral Beyond Evolution

Product Description

The KENNAMETAL 5533156 is a carbide cutoff insert designed for parting and cut-off operations on CNC lathes and turning centers. Part of the Beyond Evolution series, this single-end insert features a 2.00 mm cutting width (0.0787 inch), a neutral lead angle, and a CVD-applied TiOCN coating over a KCU25 carbide grade substrate. The EC-U insert style and CR chipbreaker geometry support controlled chip evacuation during grooving and parting cuts. Licensed machinists and CNC lathe operators install this insert into compatible Beyond Evolution toolholders as a direct replacement when the cutting edge is worn or chipped.

This insert is suited for parting and grooving applications in production turning environments, including both light and medium-duty cut-off work. The KCU25 grade with CVD TiOCN coating is formulated for steel and general-purpose turning materials. The 2-degree relief angle and 0.0080-inch corner radius support clean entry and controlled chip formation during cut-off. It is sold individually per package, with a minimum order quantity of 10 units, making it appropriate for shop stock replenishment on high-run turning operations.

Key Features

• 2.00 mm cutting width (0.0787 inch) for precise parting and grooving cuts
• KCU25 carbide grade with CVD-applied TiOCN coating for wear resistance on steel
• Neutral lead angle and neutral hand for straightforward radial cut-off setups
• CR chipbreaker geometry promotes chip control during parting operations
• 2-degree relief angle reduces rubbing and extends edge life
• Single-end insert — replace when worn, no re-indexing to a second edge

Compatibility

Designed for use with compatible KENNAMETAL Beyond Evolution series cut-off and grooving toolholders accepting EC-U style inserts with insert seat size 2. Verify toolholder seat size and insert style code before ordering.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Use the correct torque wrench and manufacturer-specified clamping hardware to seat the insert securely — do not over-torque or use improvised tools. Inspect the insert pocket and clamping screw for wear or damage each time the insert is changed.
