Kennametal 1113536 Grooving Insert NR4094 K68 Carbide

Product Description

The KENNAMETAL 1113536 is a solid carbide grooving insert designed for precision external grooving and parting operations on CNC lathes and turning centers. Built to the NR insert style in the Top Notch series, this uncoated K68-grade carbide insert delivers consistent performance in applications where sharp edges and tight dimensional tolerances are required. It carries a cutting width of 4.78 mm (0.1882 inches) and a maximum depth of cut of 6.35 mm (0.2500 inches). The full-radius geometry with a corner radius of 2.39 mm (0.0941 inches) suits it well for groove bottom profiling. Licensed machinists and CNC operators install this insert as part of standard tooling changes.

This insert is configured for left-hand cutting and is suited for grooving operations in metalworking environments, including job shops and production machining facilities. The neutral rake geometry supports stable chip flow across a range of workpiece materials. The K68 grade and uncoated bright finish make it particularly appropriate for cast iron, hardened steels, and abrasive non-ferrous materials where coated grades may not offer an advantage. It seats into Top Notch insert seat size 4 toolholders. This insert is sold individually but is subject to a minimum order quantity of 5 units.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down the machine and confirm the spindle is fully stopped before changing inserts. Seat the insert fully into the toolholder pocket and secure the clamping mechanism to the toolholder manufacturer's specified procedure. Inspect the insert seat for chips or debris before seating to avoid insert rocking or premature edge failure.
