Kennametal 1113182 Grooving Insert K313 Carbide Top Notch

Product Description

The KENNAMETAL 1113182 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Built to the NBD3 insert style within Kennametal's Top Notch series, this right-hand insert delivers a cutting width of 0.1949 inches (4.95 mm) with a bright, uncoated finish. The K313 grade carbide substrate is suited for applications demanding tight tolerances and consistent chip control. Machinists and toolroom professionals install this insert into compatible Top Notch grooving toolholders for external grooving, parting, and profile turning operations.

This insert is intended for use in metalworking environments where repeatable groove geometry is required. The NBD insert style with a 55-degree included angle and size 3 form factor makes it appropriate for medium-duty grooving on ferrous and non-ferrous workpiece materials falling within C3 and C4 material grade classifications. It is not a multi-use tool and is optimized for dedicated grooving passes. A licensed machinist or CNC operator typically selects and installs this insert during tooling setup.

Installation Notes

This insert is installed by a machinist or CNC tooling technician into a compatible Top Notch series grooving toolholder. Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and insert clamp screw per the toolholder manufacturer's torque specification. Inspect the insert pocket and clamping mechanism for wear or debris before seating the new insert.
