Kennametal 1818116 Grooving Insert KC5010 Solid Carbide

Product Description

The KENNAMETAL 1818116 is a solid carbide grooving insert in the Top Notch series, designed for external grooving and parting operations on CNC turning centers and lathes. It carries a KC5010 grade designation with a PVD-applied TiAlN coating, delivering wear resistance and edge stability on a wide range of workpiece materials. The insert is right-hand orientation with a 0.0941 inch (2.39 mm) cutting width and a maximum depth of cut of 0.2500 inch (6.35 mm). A positive rake angle of 10 degrees and a K-style chip breaker geometry work together to control chip flow and reduce cutting forces during grooving passes.

This insert is suited for precision grooving in production and job-shop environments where consistent groove width and clean sidewall finish are required. The Top Notch series is a widely used platform in CNC turning applications covering both steel and exotic alloy workpieces. The KC5010 grade is positioned for finishing to light roughing cuts. With an included angle of 55 degrees and a corner radius of 0.0075 inch (0.19 mm), this insert is appropriate for tight-tolerance groove profiles. Licensed machinists and CNC operators working in general metalcutting applications are the primary installers.

Key Features

• Solid carbide substrate with KC5010 grade rating, covering C3 and C4 material classifications
• PVD TiAlN coating for improved wear resistance and thermal stability at the cutting edge
• Right-hand cutting orientation with a 0.0941 inch (2.39 mm) cutting width
• Maximum depth of cut of 0.2500 inch (6.35 mm); effective range 0.2000 to 0.3000 inch
• Positive rake angle (10 degrees) and K chip breaker geometry for controlled chip evacuation
• Corner radius of 0.0075 inch (0.19 mm) supports tight groove profile tolerances

Compatibility

Designed as a replacement or production insert for Top Notch series grooving toolholders accepting NGD-style inserts with insert size 3094. Confirm toolholder seat geometry and insert style designation before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the turret locked before seating or removing any insert. Use the correct torque wrench and clamping hardware specified by the toolholder manufacturer — do not use substitute fasteners. Inspect the toolholder pocket for wear or debris before seating the insert, as a contaminated seat directly affects groove width accuracy and insert life.
