Kennametal 3791306 Grooving Insert KCP25 Solid Carbide

Product Description

The KENNAMETAL 3791306 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. It carries the A4G0405GUP geometry designation with a KCP25 manufacturer grade, combining a TiN coating applied via CVD process with a positive rake angle for efficient chip formation. The insert delivers a 4.05 mm cutting width and a maximum depth of cut of 3.40 mm, making it suited to moderate-depth grooving where dimensional consistency is critical. Machinists and CNC programmers working in production turning environments specify this insert for its controlled chip-breaking performance through the GUP chip breaker configuration.

This insert is intended for use in Series A4 grooving toolholders in both roughing and finishing grooving passes on turned components. It is rated for material grades C2, C3, C6, and C7, covering a range of cast irons, non-ferrous materials, and some steel applications. The neutral hand orientation allows the insert to be used in straight-plunge grooving setups. It is packaged individually with a minimum order quantity of 10 units, which is standard for production tooling replenishment programs in machine shops and manufacturing facilities.

Compatibility

Designed for use with Series A4 grooving toolholders accepting insert seat size 4. Compatible with material grades C2, C3, C6, and C7 as specified by the manufacturer.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Do not exceed the maximum depth of cut rating for the insert grade and geometry in use.
