Kennametal 1817627 Grooving Insert NG3M150K KC5025 1.5mm

Product Description

The KENNAMETAL 1817627 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. Designated style NG3M150K with grade KC5025, this insert features a TiAlN coating applied via PVD process, delivering excellent wear resistance and thermal stability in steel and cast iron applications. The left-hand cutting orientation, 1.5 mm cutting width, and 2.39 mm maximum depth of cut make it well suited for tight-tolerance groove profiles. A positive rake angle of 10 degrees and K-style chip breaker promote controlled chip evacuation and reduced cutting forces during interrupted or continuous cuts.

This insert is used in the Top Notch series tooling system, a widely adopted platform in production turning environments. It is suited for residential machine shops and industrial production floors alike, where grooving of ferrous and non-ferrous workpieces is performed at moderate to high cutting speeds. The PVD TiAlN coating extends tool life in dry or minimal-lubrication cutting conditions. Machinists and CNC operators working with steel, alloy steel, and cast iron will find this insert appropriate for groove depths ranging from 2.00 mm to 3.00 mm. Sold individually per package with a minimum order quantity of 5 units.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician following the toolholder manufacturer's torque and seating procedures. Ensure the machine spindle is fully stopped and the machine is in a safe, locked-out state before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating the new insert. Do not exceed the maximum depth of cut specification for this insert grade and style.
