Kennametal 1114286 Grooving Insert KC730 Carbide Tin

Product Description

The KENNAMETAL 1114286 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and cutoff operations on CNC lathes and turning centers. It carries a KC730 manufacturer grade with a PVD-applied TiN coating, providing a wear-resistant cutting edge suited for steel, cast iron, and similar workpiece materials in the C2, C3, and C4 material grade ranges. The insert has a right-hand orientation, a cutting width of 0.1252 inches (3.18 mm), and a maximum depth of cut of 0.1098 inches (2.79 mm). A positive rake angle of 10 degrees and a K-style chip breaker promote clean chip evacuation during grooving passes.

This insert is intended for use in Top Notch compatible toolholders on production turning equipment. It suits grooving applications where controlled chip flow and dimensional accuracy are required. The insert size is 2125 with a corner radius of 0.0075 inches (0.19 mm), making it appropriate for moderate-width grooves in medium-to-light stock removal scenarios. It is used by machinists and CNC operators in job shop and production environments.
