Kennametal 3397246 Grooving Insert KC5010 2mm Top Notch

Product Description

The KENNAMETAL 3397246 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Running in the Top Notch insert series, this right-hand insert carries a PVD-applied AlTiN coating and a KC5010 manufacturer grade, making it well-suited for dry or semi-dry cutting in steel and cast iron applications. It delivers a 2.00 mm cutting width and supports a maximum depth of cut of 4.06 mm. The K-style chip breaker geometry promotes controlled chip evacuation in finish and semi-finish grooving passes.

This insert is intended for metalworking professionals and machining operations where tight groove tolerances and consistent tool life are required. It fits lathe toolholders that accept the Top Notch NGD insert style with a clamp-type holding method. Typical applications include external grooving on medium-alloy and hardened materials in job-shop and production turning environments. The metric sizing and NGD3M200K insert designation make it straightforward to spec into existing Top Notch toolholder setups.

Key Features

Compatibility

Designed for use with Top Notch series NGD-style clamp-type grooving toolholders accepting the NGD3M200K insert size designation.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before indexing or replacing inserts, disengage the machine spindle and follow lockout/tagout procedures per applicable shop safety standards. Seat the insert fully into the toolholder pocket and verify clamp engagement before resuming cuts. Do not exceed the rated maximum depth of cut for this insert style.
