Kennametal 1952753 Grooving Insert KC5025 Solid Carbide

Product Description

The KENNAMETAL 1952753 is a solid carbide grooving insert designed for precision groove turning and parting operations on CNC lathes and turning centers. Manufactured to the G405GMP geometry in the KC5025 grade, this insert features a PVD-applied TiAlN coating for improved wear resistance and thermal stability at the cutting edge. The neutral hand orientation makes it suitable for straight plunge grooving. Cutting width is 4.05 mm (0.1594 inches) with a maximum depth of cut of 3.50 mm (0.1378 inches). A corner radius of 0.80 mm (0.0315 inches) and a GMP chip breaker geometry support controlled chip evacuation in a range of workpiece materials. This insert is installed by machinists and CNC lathe operators working in production or job-shop environments.

The 1952753 is suited for grooving applications in ferrous and non-ferrous materials where a metric-dimensioned insert is specified. The A4 series designation and insert seat size 4 match this insert to compatible A4-series grooving toolholders. The GMP chip breaker is optimized for general-purpose grooving at moderate feed and depth-of-cut conditions. The KC5025 carbide grade is rated for material grades C2 and C6, covering a broad range of steel and cast-iron applications. Typical use cases include external grooving, snap-ring groove machining, and undercut operations on turned components in medium to high-volume production settings.

Key Features

• 0.80 mm (0.0315 inches) corner radius for controlled edge engagement
• GMP chip breaker geometry for reliable chip control in general-purpose grooving
• Positive rake geometry reduces cutting forces at the insert edge

Compatibility

Designed for use with A4-series grooving toolholders accepting insert seat size 4. The manufacturers catalog number for this insert is A4G0405M04U08GMP. Verify toolholder insert pocket specifications before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the machine spindle before seating or changing inserts. Use the correct torx or hex key at the manufacturer-specified torque range for the toolholder clamping screw — refer to the toolholder documentation for that value, as it is not specified here. Inspect the insert seat and clamping surfaces for chips or debris before seating the new insert to ensure proper contact and edge alignment.
