Kennametal 1952738 Grooving Insert KC5010 5.05mm

Product Description

The KENNAMETAL 1952738 is a solid carbide grooving insert designed for precision external and internal grooving operations on CNC lathes and turning centers. Manufactured in the A4 series with a G505GMN geometry, it features a TiAlN coating applied via PVD process for high heat resistance and extended tool life in interrupted cuts and continuous grooving. The cutting width is 5.05 mm (0.1988 inches) with a maximum depth of cut of 4.2 mm (0.1654 inches). The insert carries a neutral hand orientation, making it suitable for both left- and right-hand toolholders designed for this geometry. Machinists and CNC operators working in production shops install this insert as part of a qualified tooling system.

This insert is intended for grooving and parting applications on ferrous and non-ferrous workpiece materials classified under material grades C3 and C4. The GMN chip breaker geometry controls chip formation in medium-depth grooving passes. The A4 series designation indicates compatibility with Kennametal A4-series toolholders. The insert is marked multi-use, meaning it may be indexed or repositioned within the holder per standard insert-change procedures. Typical applications include OD grooving, face grooving, and light parting on production lathes in industrial and job-shop environments.

Compatibility

Designed for use with Kennametal A4-series grooving toolholders. The manufacturers catalog number for this insert is A4G0505M05U04GMN. Verify toolholder pocket specifications before installation to confirm seat and clamping compatibility.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician with the machine in an E-stop or powered-down state and all axes at a safe reference position. Use the appropriate torx or clamping key specified by the toolholder manufacturer to seat and secure the insert — do not overtighten by feel alone; follow the toolholder clamp specification. Inspect the insert pocket and seating surface for chips or debris before installing a new insert. Dispose of worn carbide inserts according to local regulations for carbide and metal waste.
