Kennametal 1113535 NR4062 K68 Grooving Insert Left Hand

Product Description

The KENNAMETAL 1113535 is a solid carbide grooving insert from the Top Notch series, designed for external grooving and parting operations on CNC lathes and turning centers. It carries the K68 uncoated carbide grade with a neutral rake geometry and full radius profile. The cutting width measures 0.125 inches (3.18 mm), and the maximum depth of cut reaches 0.150 inches (3.81 mm). This is a left-hand insert, meaning it is configured for right-to-left feed direction. Machinists and CNC operators working with cast iron and non-ferrous materials will find the K68 grade well suited to their applications.

This insert is intended for use in Top Notch series toolholders that accept a size 4 insert seat. It is suited for precision grooving, undercutting, and parting in production turning environments, including both job shops and high-volume manufacturing. The full corner radius of 0.063 inches (1.59 mm) provides a smooth groove floor finish. The metric insert size designation is 4062, and the material grade classification is C3, which corresponds to applications involving cast iron and hardened non-ferrous materials.
