Kennametal 1818362 Grooving Insert KC5025 4.80mm Carbide

Product Description

The KENNAMETAL 1818362 is a solid carbide grooving insert designed for precision external grooving and turning operations. Built to the Top Notch series standard, it features a TiAlN coating applied via PVD process, delivering strong wear resistance and thermal stability at cutting speeds typical of steel and cast iron machining. The insert carries a 4.80 mm (0.1890 inch) cutting width and a maximum depth of cut of 9.53 mm (0.3752 inch). A positive rake angle of 10 degrees and a K-style chip breaker promote controlled chip flow and reduced cutting forces. Machinists and CNC operators in production and job-shop environments rely on this insert for consistent groove geometry and extended tool life.

This insert is suited for grooving applications on CNC lathes and turning centers handling steel, cast iron, and similar workpiece materials rated in the C2 and C6 material grade range. The right-hand orientation fits standard Top Notch series toolholders with an insert seat size of 4. The included angle of 55 degrees and a corner radius of 0.57 mm (0.0225 inch) make it appropriate for tight-tolerance groove profiles in both high-volume production runs and low-volume precision work. It is not configured as a multi-use or full-radius insert, so application selection should match the stated geometry.

• KC5025 manufacturer grade rated for C2 and C6 material grades

Compatibility

Designed for use with Top Notch series toolholders accepting insert seat size 4 and insert style NGD. MSC and manufacturer cross-reference number is NGD4189R/LK.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or CNC tooling technician following the toolholder manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert seat and clamping screw for debris or wear before seating a new insert. Do not exceed the stated maximum depth of cut range of 9.53 mm for this geometry.
