Kennametal 2274949 Grooving Insert KC5025 Carbide Tialn

Product Description

The KENNAMETAL 2274949 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Manufactured to Series A4 specifications, this insert features a G04GMN chipbreaker geometry with a TiAlN coating applied via PVD process, delivering strong wear resistance and thermal stability at cutting temperatures. The insert carries a Neutral hand orientation, a cutting width of 4.76 mm (0.1874 inches), and a maximum depth of cut of 3.5 mm (0.1378 inches). Machining shops and toolroom technicians handling high-volume turning work install this insert as a direct OEM-grade component in compatible Kennametal grooving toolholders.

This insert is suited for grooving, part-off, and profiling operations in production machining environments. The KC5025 grade is formulated for interrupted and continuous cuts in steel, cast iron, and similar workpiece materials where PVD TiAlN coatings provide a balance of edge toughness and surface hardness. The GMN chipbreaker geometry is engineered to control chip flow during moderate-depth groove passes, making it appropriate for both high-production floor environments and precision toolroom applications. Insert Size 04 with an Insert Seat Size of 4 fits toolholders designed to the A4 series standard.

Key Features

• TiAlN coating via PVD process for elevated wear resistance and thermal stability
• GMN chipbreaker geometry for controlled chip evacuation during grooving passes
• Neutral hand orientation accommodates both left- and right-side grooving setups
• 4.76 mm cutting width with a corner radius of 0.80 mm (0.0315 inches) for precise groove profiling
• KC5025 carbide grade rated for steel and cast iron applications at moderate to aggressive cutting parameters
• Full Radius: No — suitable for flat-bottom groove profiles

Compatibility

Designed as an OEM-style replacement grooving insert for Series A4 Kennametal grooving toolholders accepting Insert Seat Size 4, as referenced by Manufacturers Catalog Number A4G187I04P2GMN. No additional compatible model numbers were specified in the available product data.

Installation Notes

This insert is installed and replaced by qualified machinists or toolroom technicians familiar with indexable carbide tooling. Before changing inserts, power down the machine spindle, engage the E-stop, and confirm zero spindle rotation per lockout/tagout procedures. Use the appropriate torque wrench or insert-clamping tool specified for the A4-series toolholder — do not over-torque the clamp screw, as this can fracture the carbide insert or damage the seat. Inspect the insert pocket and seating surface for chips or debris before seating a new insert.
