Kennametal 1113198 Grooving Insert NB3 K313 Solid Carbide

Product Description

The KENNAMETAL 1113198 is a solid carbide grooving insert designed for external grooving and turning operations on CNC lathes and turning centers. Built to the Top Notch series standard, this uncoated insert features a right-hand cutting orientation and a 0.1949-inch (4.95 mm) cutting width. The K313 carbide grade delivers the hardness and edge retention needed for finishing and semi-finishing cuts in cast iron and non-ferrous materials. Machinists and toolroom technicians install this insert into compatible Top Notch toolholders for precise groove geometry control. The 55-degree included angle and NB insert style provide consistent performance in production environments.

This insert is suited for use on manual and CNC lathes in both job shop and production settings. The Top Notch series is a common platform in metalworking shops handling grooving, parting, and form-turning work. The NB3 size designation and right-hand configuration make it a direct fit for corresponding Top Notch series toolholders used in light to medium-duty grooving applications. The solid carbide construction without coating is preferred in applications where built-up edge is a concern and where the workpiece material benefits from a sharp, uncoated cutting edge.

Compatibility

Designed for use with Top Notch series toolholders accepting NB3 style inserts. The MSC and manufacturer cross-reference number for this insert is NB3R/L. Verify toolholder pocket specifications before installation to confirm proper insert seating and clamping.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine in a full stop, locked-out state. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer to seat the insert securely in the pocket. Inspect the insert pocket for chips or debris before seating the insert, as contamination affects insert positioning and surface finish. Do not exceed the cutting parameters recommended for the K313 grade and the specific workpiece material.
