Kennametal 1114226 Grooving Insert NR4094K KC730 Carbide

Product Description

The KENNAMETAL 1114226 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. Designated style NR4094K with a KC730 grade, this left-hand insert features a 4.78 mm cutting width and a maximum depth of cut of 6.35 mm. The PVD-applied TiN coating improves wear resistance and extends tool life in demanding cutting applications. A full radius nose profile and positive 10-degree rake angle promote clean chip formation and reduce cutting forces. Machinists and CNC operators working with ferrous and non-ferrous materials install this insert as part of a modular Top Notch toolholder system.

This insert is suited for grooving, parting, and profiling operations on lathes and turning centers in production machining environments. The KC730 carbide grade and TiN finish make it effective across material grades C2, C3, and C4, which correspond to a broad range of cast irons and non-ferrous materials. The K chip breaker geometry is optimized for controlled chip evacuation in medium to light cuts. It is sold individually but carries a minimum order quantity of 5 units, making it appropriate for shop stock replenishment or toolroom inventory.

Installation Notes

This insert is installed and replaced by qualified machinists or CNC toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or removing the insert. Use the appropriate Top Notch clamping screw and torque tool as specified by the toolholder manufacturer. Inspect the insert seat for chips or debris before installation to ensure proper seating and repeatable tool geometry.
