Kennametal 2274947 Grooving Insert KC5025 3.18mm Series A4

Product Description

The KENNAMETAL 2274947 is a solid carbide grooving insert designed for precise external and internal grooving operations on CNC lathes and turning centers. Manufactured to the G03GMN insert style with a neutral hand orientation, this insert features a TiAlN coating applied via PVD process, which provides enhanced wear resistance and thermal stability at elevated cutting temperatures. The KC5025 grade is suited for a broad range of workpiece materials. Key dimensional specs include a 3.18 mm cutting width and a maximum depth of cut of 3.40 mm. The GMN chip breaker geometry supports controlled chip evacuation during grooving passes.

This insert is intended for use in Series A4 toolholders and is applicable to precision grooving in production machining environments, including automotive, aerospace, and general metalworking applications. The neutral hand configuration allows flexible deployment in both right-hand and left-hand holder setups. It is sold individually but must be ordered in multiples of 10. Machinists and CNC programmers working on tight-tolerance groove profiles will find the 0.40 mm corner radius and full-radius-free geometry useful for maintaining dimensional accuracy in groove sidewalls and bottoms.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping guidelines. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Do not exceed the rated maximum depth of cut for this insert style.
