Kennametal 1114333 Grooving Insert NG3156K KC730 Carbide

Product Description

The KENNAMETAL 1114333 is a solid carbide grooving insert in the Top Notch series, designed for left-hand grooving and parting operations on CNC lathes and turning centers. It carries the KC730 grade designation with a PVD-applied TiN finish, which improves wear resistance and tool life in demanding cutting applications. The insert features a 3.96 mm (0.1559 inch) cutting width and a maximum depth of cut of 3.81 mm (0.1500 inch). A positive rake angle of 10 degrees and the K chip breaker geometry help control chip flow and reduce cutting forces. This insert is installed by machinists and tooling technicians working in production turning environments.

The 1114333 is suited for grooving operations on ferrous and non-ferrous workpiece materials classified under material grades C2, C3, and C4. It fits standard Top Notch series toolholders that accept NG-style inserts in the 3156 size. The left-hand orientation makes it appropriate for right-to-left grooving passes. The K chip breaker is intended for light to moderate chip loads, and the 55-degree included angle with a 0.19 mm (0.0075 inch) corner radius supports accurate groove geometry in tight tolerance work.

Compatibility

Designed for use with Top Notch series toolholders that accept NG-style inserts in the 3156 size. Compatible with material grades C2, C3, and C4 workpiece materials.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine before seating or removing the insert. Ensure the toolholder pocket is clean and free of chips or debris before installation, as contamination can affect seating and contribute to premature insert failure. Do not exceed the rated maximum depth of cut for this insert geometry.
