Kennametal 1114322 Grooving Insert KC730 Carbide Tin

Product Description

The KENNAMETAL 1114322 is a solid carbide grooving insert in the Top Notch series, designed for precise external grooving operations on CNC lathes and turning centers. It carries the KC730 manufacturer grade with a PVD-applied TiN coating for wear resistance in demanding cutting conditions. The insert features a right-hand cutting orientation, a 3.18 mm (0.1252 inch) cutting width, and a maximum depth of cut of 6.35 mm (0.2500 inch). The positive rake angle of 10 degrees and K-style chip breaker promote efficient chip evacuation. Installed by machinists and CNC operators, this insert is suited for production turning in metalworking environments.

This insert is intended for grooving applications on turning centers and lathes where controlled chip flow and dimensional accuracy are required. The Top Notch series designation indicates compatibility with Top Notch-style toolholders. It is applicable to material grades C2, C3, and C4, making it suitable for a range of steel and cast iron workpieces. The maximum depth of cut range spans 5.00 mm to 10.00 mm (0.2000 to 0.3000 inch), covering standard groove depth requirements in typical production turning scenarios.
