Kennametal 5988772 Grooving Insert KCU25 6mm Beyond Evolution

Product Description

The KENNAMETAL 5988772 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured in the Beyond Evolution series, this insert carries a KCU25 grade designation and features a PVD-applied AlTiN coating that provides thermal resistance and extended tool life in demanding cutting environments. The neutral hand orientation and GUP chip breaker geometry deliver a positive rake angle of 27 degrees, promoting clean chip evacuation and reduced cutting forces. A 6.00 mm cutting width and maximum depth of cut of 4.00 mm make this insert well suited to medium-width groove applications requiring tight dimensional control.

This insert is intended for use in metalworking environments where consistent groove geometry and surface finish are critical. The EG-P insert style is compatible with KENNAMETAL Beyond Evolution grooving toolholders and blade systems. Typical applications include grooving, undercutting, and parting on steel, stainless, and similar workpiece materials. It is installed by machining professionals, CNC setup technicians, and toolroom machinists working in production or job-shop settings.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before seating or removing the insert. Use the correct torque wrench and insert clamp hardware specified by the toolholder manufacturer — do not over-tighten the clamping screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating a new insert to ensure proper contact and repeatable tool geometry.
