Kennametal 1113090 NG4213 KC730 Grooving Insert Left Hand

Product Description

The KENNAMETAL 1113090 is a solid carbide grooving insert in the NG4213 style, designed for external grooving and parting operations on CNC lathes and turning centers. Manufactured to the KC730 grade with a PVD-applied TiN coating, this insert offers the wear resistance and edge integrity that production machinists demand. The left-hand orientation and neutral rake geometry make it well suited for specific toolholder setups in the Top Notch series. Cutting width is 5.41 mm (0.213 inches) and maximum depth of cut is 6.35 mm (0.250 inches). Corner radius is 0.19 mm (0.0075 inches).

This insert is intended for turning applications involving steel, cast iron, and non-ferrous materials falling within C2, C3, and C4 material grades. It fits into Top Notch series toolholders with an insert seat size of 4. Typical use cases include groove turning, face grooving, and parting in both high-volume production and job-shop environments. The insert is sold individually but requires purchase in multiples of 5. CNC machinists and tool-and-die professionals are the primary installers of this product.
