Kennametal 4175951 Grooving Insert NR3031K KCU10 Carbide

Product Description

The KENNAMETAL 4175951 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. It carries the NR3031K designation in grade KCU10, featuring a Physical Vapor Deposition (PVD) AlTiN coating for improved wear resistance and elevated cutting temperatures. The insert delivers a cutting width of 1.58 mm, a maximum depth of cut of 2.39 mm, and a full radius corner profile with a 0.79 mm corner radius. A K-style chip breaker geometry manages chip flow in medium to finish turning applications. This insert is installed and changed by machinists and CNC tooling technicians.

This insert is suited for grooving operations in both production and job-shop turning environments. The right-hand cutting orientation and clamp-style holding method make it compatible with Top Notch series toolholders and boring bars configured for NR-style inserts. It is a metric-dimensioned insert with an insert size designation of 3031 and a cutting height of 8.74 mm. It is appropriate for use on materials in the C3 and C4 material grade classifications, which typically include cast iron and non-ferrous materials. Each package contains one insert, with a minimum order quantity of five units.

Compatibility

Designed for use with Top Notch series toolholders and systems accepting NR-style grooving inserts with a 3031 insert size designation. The MSC and manufacturer cross-reference number for this insert is NR3031R/LK.

Installation Notes

Installation and replacement should be performed by a qualified machinist or CNC tooling technician with the machine fully stopped and in a safe, locked-out state. Use the appropriate clamp and torx or hex key as specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamp for wear or debris before installing a new insert. Do not exceed the maximum depth of cut range of 2.00 mm to 3.00 mm for this insert size.
