Kennametal 5941071 Grooving Insert KCU25 Carbide Altin

Product Description

The KENNAMETAL 5941071 is a solid carbide grooving insert from the Beyond Evolution series, designed for precise grooving and parting operations on CNC lathes and turning centers. It carries an AlTiN coating applied via PVD process, providing thermal and wear resistance suited to demanding cutting conditions. The insert features a 4.13 mm cutting width, a maximum depth of cut of 2.75 mm, and a positive rake angle of 27 degrees. The GUP chip breaker geometry promotes controlled chip evacuation. Machinists and toolroom specialists working in production turning environments install this insert as a direct-fit replacement within compatible EG-U style toolholders.

This insert is intended for grooving applications in ferrous and non-ferrous materials where consistent chip control and dimensional accuracy are required. Its neutral hand orientation allows use on both OD and face grooving operations. The KCU25 grade is formulated for versatility across a range of workpiece materials. The Beyond Evolution series targets high-productivity turning centers in job shop and production environments where insert life and repeatability are critical performance factors.

Installation Notes

This insert is installed and replaced by a machinist or toolroom technician. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer — do not overtighten the clamping screw. Inspect the insert pocket and clamping surfaces for debris or wear before seating the new insert.
