Kennametal 1113583 Grooving Insert NG3189 K68 Carbide

Product Description

The KENNAMETAL 1113583 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the NG insert style in the Top Notch series, it delivers a 4.80 mm (0.189 inch) cutting width and a maximum depth of cut of 3.81 mm (0.150 inch). The K68 grade is an uncoated, bright-finish carbide formulated for cutting non-ferrous and cast materials where a sharp, slick edge is required. With a neutral rake and a 0.57 mm corner radius, this insert produces clean, consistent groove profiles with minimal burring. It is installed and replaced by machinists and CNC tooling technicians as part of scheduled insert rotation.

This insert is suited for grooving operations on lathes running non-ferrous metals, cast iron, and similar materials where the K68 carbide grade performs best. The right-hand cutting orientation fits standard Top Notch toolholders configured for right-hand operation. Typical applications include groove turning, undercutting, and parting on medium to short-run production work. The NG3189 insert size positions this part in medium-duty grooving applications where dimensional accuracy and edge consistency are priorities.

Compatibility

Designed as an OEM-style replacement insert for Top Notch series toolholders accepting the NG3189 insert style in right-hand configurations.

Installation Notes

This insert is installed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the toolholder pocket and verify the clamping screw torque per the toolholder manufacturer's specification. Inspect the pocket and clamping components for wear or debris before seating a new insert, as a contaminated pocket will affect dimensional accuracy and edge life.
