Kennametal 1952701 Grooving Insert G305GMN KC5025 Carbide

Product Description

The KENNAMETAL 1952701 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. It carries the G305GMN chipbreaker geometry and KC5025 grade designation, with a TiAlN coating applied via PVD process for enhanced wear resistance and thermal stability at elevated cutting speeds. The insert has a neutral hand orientation, a cutting width of 3.05 mm (0.1201 inches), and a maximum depth of cut of 3.50 mm (0.1378 inches). It belongs to the Series A4 platform and is suited for machinists and toolroom professionals working in production or job-shop turning environments.

This insert is applied in external and internal grooving, recessing, and light parting operations on ferrous and non-ferrous workpiece materials. The GMN chipbreaker geometry promotes controlled chip formation across a range of feed rates, making it well-suited for both roughing and finishing groove passes. The KC5025 grade is commonly selected for interrupted cuts and applications requiring edge toughness combined with wear resistance. The insert fits turning toolholders designed for the Series A4 platform. The manufacturer catalog number is A4G0305M03U02GMN.

Installation Notes

Insert installation should be performed by a qualified machinist or toolroom technician with the machine spindle fully stopped and locked out per facility lockout/tagout procedures. Ensure the toolholder pocket and clamping surfaces are clean and free of chips or debris before seating the insert. Do not exceed the maximum depth of cut rating for this insert geometry. Torque clamping screws only to the toolholder manufacturer specifications — do not estimate or exceed stated values.
