Kennametal 1952743 Grooving Insert KC5010 Tialn 3.05mm

Product Description

The KENNAMETAL 1952743 is a solid carbide grooving insert with a TiAlN PVD coating, designed for external grooving and parting operations on CNC lathes and turning centers. It carries the G305GMP designation, indicating a 3.05 mm cutting width and a GMP chip breaker geometry optimized for controlled chip evacuation. The insert runs in a neutral hand orientation and delivers a maximum depth of cut of 3.5 mm. With a positive rake angle and a fine 0.20 mm corner radius, it is suited for finishing and semi-finishing passes where dimensional accuracy and surface finish are priorities. Machinists and CNC operators in production and job-shop environments are the primary installers.

This insert is applied in metric-dimensioned turning setups where grooving depths fall in the 3.00 mm to 4.00 mm range. The KC5010 grade is a PVD TiAlN-coated carbide formulation rated for material grades C3 and C4, making it applicable to a broad range of steel, stainless steel, and cast iron workpieces at moderate to high cutting speeds. It seats into Series A4 grooving toolholders and is indexed as a single-edge insert. Typical use cases include O-ring grooves, snap-ring grooves, undercuts, and parting cuts on turned components in automotive, aerospace, and general manufacturing applications.

Key Features

• 3.05 mm cutting width with a maximum depth of cut of 3.5 mm
• TiAlN PVD coating for wear resistance at elevated cutting temperatures
• GMP chip breaker geometry for positive chip control in grooving operations
• Positive rake angle reduces cutting forces and heat generation at the workpiece
• 0.20 mm corner radius for accurate groove geometry and reduced stress concentration
• Series A4 insert platform for compatibility with standard A4 grooving holders

Compatibility

Designed for use with Series A4 grooving toolholders. The manufacturer catalog number for this insert is A4G0305M03U02GMP. Consult the KENNAMETAL toolholder catalog to confirm the correct A4 holder for this insert geometry before ordering.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the insert. Use the torque wrench and clamping hardware specified by the toolholder manufacturer — do not substitute fasteners. Verify insert seating and clamping force before resuming cuts, and inspect the pocket and clamping surfaces for chips or debris that could affect insert registration.
