Kennametal 1817979 Grooving Insert NG2047K KC5025

Product Description

The KENNAMETAL 1817979 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Carrying the NG insert style designation and manufactured to the KC5025 grade, it features a PVD-applied TiAlN coating that provides thermal resistance and wear protection in demanding cut conditions. The insert delivers a cutting width of 1.19 mm and a maximum depth of cut of 1.27 mm, making it suited for fine, controlled groove profiles. It is part of the Top Notch series and is intended for installation by machinists and CNC tooling technicians working in production turning environments.

This insert is used in external grooving and light parting applications on ferrous and non-ferrous workpiece materials. The right-hand configuration suits standard lathe setups where the tool advances from right to left. The positive rake angle of 10 degrees and K chip breaker geometry help manage chip flow in shallow, narrow grooves. Typical installations involve production shops running medium-to-high cutting speeds where PVD-coated carbide grades in the C2 and C6 material grade range are appropriate for the workpiece material being machined.

Compatibility

Designed for use with Top Notch series NG-style toolholders compatible with size 2047 inserts. The MSC and manufacturer cross-reference number for this insert is NG2047R/LK. Verify toolholder seat and clamping compatibility before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate torx or hex key as specified by the toolholder manufacturer to secure the clamping screw to the recommended feel-tight standard without overtightening. Inspect the insert seat for chips or debris before seating the insert to ensure proper contact and runout performance.
