Kennametal 3388460 Grooving Insert NR2M050 KC5025

Product Description

The KENNAMETAL 3388460 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Manufactured in the NR insert style with a right-hand cutting orientation, this insert carries the KC5025 grade designation, a carbide grade engineered for wear resistance and toughness in interrupted and continuous turning cuts. The compact 2M050 insert size makes it well suited for narrow groove profiles. Machinists and tooling specialists working in production turning environments install this insert into compatible NR-style grooving toolholders for repeatable, accurate groove geometry.

This insert is intended for use in metalworking and machining applications, including the grooving of steel, stainless steel, cast iron, and similar ferrous workpiece materials. It is a common replacement insert in job shop and production CNC turning operations where consistent groove width and depth control are required. The right-hand cutting geometry suits standard lathe setups where the tool advances from right to left. Installation is performed by qualified machinists or tooling technicians as part of routine insert indexing and replacement.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machine spindle before indexing or replacing any insert. Seat the insert firmly and evenly in the toolholder pocket and verify clamp screw torque per the toolholder manufacturer instructions. Inspect the insert seat and clamp for debris or wear before installing a new insert.
