Kennametal 1114267 NRP3094 KC730 Grooving Insert Carbide

Product Description

The KENNAMETAL 1114267 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and turning operations on CNC lathes and turning centers. Manufactured to grade KC730 with a PVD-applied TiN coating, this insert delivers consistent wear resistance in a range of materials including cast iron, steel, and non-ferrous alloys corresponding to material grades C2, C3, and C4. The right-hand configuration features a 4.78 mm cutting width, a maximum depth of cut of 3.81 mm, and a full corner radius of 2.39 mm with a positive 5-degree rake angle. Machinists and toolroom technicians install this insert in compatible Top Notch toolholders for precision groove profiling.

This insert is suited for production turning environments where repeatable groove geometry and tight tolerances are required. The NRP-style insert with insert size designation 3094 fits Top Notch series toolholders configured for right-hand operation. Typical applications include external groove profiling, parting-adjacent grooving, and contour turning in both light and moderate cutting conditions on manual and CNC turning equipment. It is sold individually per package with a minimum order quantity of 5 units.
