Kennametal 1113605 Grooving Insert NG3094 K68 Carbide

Product Description

The KENNAMETAL 1113605 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Built to the NG insert style within the Top Notch series, this left-hand insert delivers a cutting width of 2.39 mm (0.0941 inches) and a maximum depth of cut of 3.81 mm (0.1500 inches). The K68 grade carbide substrate is bright and uncoated, making it well suited for finishing cuts on cast iron, nonferrous metals, and other abrasive materials where a sharp, uncoated edge performs reliably. Machinists and toolroom technicians install this insert as a direct drop-in for compatible Top Notch toolholders.

This insert is used in production and job-shop turning environments where consistent groove geometry and tight tolerances are required. The neutral rake geometry and 55-degree included angle support stable chip formation during shallow to medium-depth grooving passes. It is appropriate for light-duty finishing and profiling work on components where groove width and corner geometry must be held to close tolerances. The 0.19 mm (0.0075 inch) corner radius limits the insert to applications where a near-sharp corner is specified rather than a large blended radius.

• K68 solid carbide grade, bright and uncoated - optimized for abrasive and nonferrous materials
• Left-hand orientation with neutral rake and 55-degree included angle
• Small corner radius of 0.19 mm (0.0075 inches) for near-sharp corner geometry

Compatibility

Installation Notes

This insert is installed by a qualified machinist or toolroom technician following the toolholder manufacturer's clamping procedure for Top Notch insert seats. Power down and lock out the machine spindle before changing inserts. Use the correct torx or clamping key specified for the toolholder - never use substitute tools that can cam out and damage the clamping screw. Inspect the insert pocket for chips or wear before seating the new insert to ensure proper support and alignment.
