Kennametal 1112962 Grooving Insert NR2031 KC730 Carbide

Product Description

The KENNAMETAL 1112962 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries the KC730 grade with a PVD-applied TiN coating, delivering wear resistance and edge stability across a range of workpiece materials. The insert features a 1.58 mm cutting width and a maximum depth of cut of 2.79 mm, making it well suited for narrow, precise grooves. The full-radius geometry with a 0.79 mm corner radius and neutral rake promotes smooth chip flow and consistent surface finish. Right-hand orientation is specified for standard turning applications.

This insert is intended for use in metal-cutting environments where tight groove tolerances are required. It is rated for material grades C2, C3, and C4, covering a broad range of cast irons and non-ferrous materials as well as general steel applications. The Top Notch series toolholder system provides the mating seat geometry for this NR2031 insert style. It is typically installed by machinists and CNC operators in production turning shops, job shops, and precision machining facilities. The insert size designation is 2031, and the MSC manufacturer reference number is NR2031R/L.

Key Features

• Solid carbide construction with KC730 grade for durability in interrupted and continuous grooving cuts
• PVD TiN coating improves surface hardness and reduces built-up edge formation
• 1.58 mm cutting width supports narrow groove applications
• Full radius geometry with 0.79 mm corner radius for consistent groove profile
• Neutral rake and 55-degree included angle for stable, balanced cutting forces
• Right-hand orientation for standard lathe setup

Compatibility

Designed for use with Top Notch series toolholders that accept the NR2031 insert style. Compatible with workpiece material grades C2, C3, and C4 as specified by the manufacturer.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. The machine must be powered down and the spindle fully stopped before seating or removing inserts. Use the appropriate torx or clamp screw specified by the Top Notch toolholder to secure the insert at the correct clamping torque per the toolholder manufacturer documentation. Inspect the insert seat and clamp for debris or damage before each insert change to ensure proper seating and safe cutting performance.
