Kennametal 4111101 Cutoff Insert KCU25 Carbide 3mm

Product Description

The KENNAMETAL 4111101 is a carbide cutoff insert designed for parting and grooving operations on CNC lathes and turning centers. It carries the style designation A2030R06CM01 and is manufactured in the KCU25 grade with an AlTiN coating applied via PVD process. The insert features a 3.00 mm (0.1180 inch) cutting width, a 6-degree right-hand lead angle, and a 2-degree relief angle. The CM chipbreaker geometry promotes controlled chip formation during cutoff passes. Toolroom machinists and CNC operators working in production turning environments install this insert into compatible A2-series clamp-style toolholders.

This insert is suited for cutoff and grooving applications on ferrous and non-ferrous materials in both production and job-shop turning environments. The KCU25 PVD-coated carbide grade is commonly applied to steel and cast iron workpieces where wear resistance and edge integrity are priorities. The single-end, clamp-held design is appropriate for external grooving and parting operations on medium-duty lathes and turning centers. The insert seat size is 3, and the part is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer when securing the clamp. Inspect the insert pocket and clamp for wear or debris before seating the new insert.
