Kennametal 1114225 Grooving Insert KC730 Carbide Tin

Product Description

The KENNAMETAL 1114225 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. This insert carries Kennametal grade KC730 with a PVD-applied TiN coating and a positive rake geometry, producing a 10-degree rake angle that reduces cutting forces and promotes clean chip flow. The cutting width measures 4.78 mm (0.1882 inches) and the maximum depth of cut is 6.35 mm (0.2500 inches). A full corner radius of 2.39 mm (0.0941 inches) is built into the insert profile. Right-hand orientation is standard. Carbide material grades C2, C3, and C4 are supported, making this insert effective across a range of workpiece materials.

This insert is suited for grooving, profiling, and light turning applications in production and job-shop environments. The Top Notch series is widely used on both manual and CNC turning equipment where consistent groove geometry and tool life are priorities. The K chip breaker geometry is optimized for controlling chip formation during continuous grooving passes. Insert seat size 4 and the NR style mounting interface are the standard fitment parameters for this insert.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine in a full stop, lockout/tagout condition. Seat and clamping surfaces should be cleaned of chips and debris before seating the insert. Follow the toolholder manufacturer torque specifications for the clamping screw. Inspect the insert seat for wear or damage before each insert change to maintain dimensional accuracy.
