Kennametal 1173652 Grooving Insert K420 Carbide Left Hand

Product Description

The KENNAMETAL 1173652 is a solid carbide grooving insert designed for precision grooving and parting operations on CNC lathes and turning centers. Manufactured to the NG1094 style in the Top Notch series, it delivers a 2.39 mm (0.0941 inch) cutting width and a maximum depth of cut of 1.91 mm (0.0752 inch). The insert carries a K420 manufacturer grade with a bright, uncoated finish and a neutral rake geometry. A 0.19 mm (0.0075 inch) corner radius and a 64-degree included angle define the cutting edge profile. This insert is sold individually and is intended for use by machinists and toolroom professionals working in production or job-shop turning environments.

The 1173652 is suited for grooving applications in materials corresponding to C2, C3, and C4 material grades, which generally cover cast iron and non-ferrous materials. Its left-hand orientation makes it appropriate for operations where the tool approaches from the left side of the workpiece. The Top Notch series toolholder system governs insert seating and clamping, so the correct compatible toolholder body must be in use. This insert fits residential and industrial turning operations where groove width consistency and depth control are critical.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping procedure for Top Notch series inserts. Power down and lock out the spindle before seating or indexing any cutting insert. Confirm the insert is fully seated in the pocket and the clamp screw is tightened to the toolholder manufacturer's specified procedure before resuming cutting. Do not exceed the rated maximum depth of cut for this insert style.
