Kennametal 1113094 Grooving Insert KC730 Solid Carbide

Product Description

The KENNAMETAL 1113094 is a solid carbide grooving insert in the Top Notch series, designed for precision grooving and parting operations on CNC lathes and turning centers. This left-hand insert carries a KC730 grade carbide substrate with a PVD-applied TiN coating for improved wear resistance and surface finish. The cutting width is 3.18 mm (0.1252 inches) and the maximum depth of cut is 3.81 mm (0.1500 inches). A neutral rake geometry and 55-degree included angle make this insert suited to a range of workpiece materials across material grades C2, C3, and C4. It is installed by machinists and CNC setup technicians on compatible Top Notch toolholders.

This insert is intended for grooving, recessing, and cut-off applications on metalworking lathes in both job shop and production environments. The K chip breaker geometry supports controlled chip evacuation during interrupted and continuous groove cuts. With a corner radius of 0.19 mm (0.0075 inches) and a lead angle of 3 degrees, the insert is well-suited for tight-tolerance groove profiles where corner definition matters. The metric sizing designation 3125 aligns with standard Top Notch insert seating dimensions.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machine spindle before seating or removing any insert.
