Kennametal 1113568 NG2125 K68 Grooving Insert Left Hand

Product Description

The KENNAMETAL 1113568 is a solid carbide grooving insert in the Top Notch series, designed for precise grooving and parting operations on CNC lathes and turning centers. This left-hand insert carries the K68 manufacturer grade, which is an uncoated bright carbide grade suited for non-ferrous and cast iron applications. The cutting width measures 3.18 mm (0.1252 inches) with a maximum depth of cut of 2.79 mm (0.1098 inches). The corner radius is 0.19 mm (0.0075 inches). A neutral rake geometry and a 55-degree included angle contribute to controlled chip formation during grooving passes.

This insert is intended for use in Top Notch series toolholders on manual and CNC turning equipment. The left-hand orientation makes it appropriate for grooving toward the tailstock or for specific workholding configurations where a right-hand insert is not suitable. The K68 solid carbide grade without coating performs well on aluminum, brass, bronze, and gray cast iron at moderate to high surface speeds. Machinists and CNC programmers in production and job shop environments typically select this insert for external grooving, OD profiling, and light parting on short-run and high-volume turning applications.
