Kennametal 5988813 Grooving Insert KCU25 Carbide 3.18mm

Product Description

The KENNAMETAL 5988813 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Part of the Beyond Evolution series, this insert features the ER-P3GUP geometry with a KCU25 grade substrate and a PVD-applied AlTiN coating that provides elevated heat resistance and extended tool life in steel and similar materials. The GUP chip breaker geometry promotes positive cutting action at a 10-degree rake angle, aiding in chip control during groove cycling. Cutting width is 3.18 mm with a maximum depth of cut of 2.21 mm. This insert is intended for machinists and toolroom professionals working in production turning environments.

This insert suits external grooving and light profiling applications in ferrous materials on CNC turning equipment. The neutral hand orientation provides flexible application in standard grooving toolholders accepting the ER-P insert style. The full-radius nose geometry, with a corner radius of 1.59 mm, is suited for groove forms requiring a radiused bottom. The insert size 3 classification fits toolholders dimensioned to that standard. Typical applications include OD groove cutting, snap-ring groove machining, and light recessing work in production-volume turning operations.

Installation Notes

Installation of grooving inserts should be performed by a qualified machinist with the machine in a locked-out, de-energized state per applicable safety procedures. Seat the insert fully in the toolholder pocket and torque the clamping screw to the toolholder manufacturer's specification. Inspect the insert seating and clamping before resuming cutting operations. Do not exceed the stated maximum depth of cut range of 2.00 mm to 3.00 mm for this insert size.
