Kennametal 1818118 Grooving Insert KC5010 Carbide Tialn

Product Description

The KENNAMETAL 1818118 is a solid carbide grooving insert designed for external grooving and parting operations on CNC lathes and turning centers. Manufactured to the NGD3125K geometry in the Top Notch series, this insert features a TiAlN coating applied via PVD process for improved wear resistance and thermal stability at elevated cutting speeds. It carries a left-hand cutting orientation and delivers a 0.125-inch (3.18 mm) cutting width with a maximum depth of cut of 0.250 inch (6.35 mm). The K chip breaker geometry and 10-degree positive rake angle promote controlled chip flow in a range of workpiece materials. Machinists and CNC operators handling steel, cast iron, and similar materials will find this insert suited to precision grooving applications.

This insert is intended for use in Top Notch series toolholders and grooving systems compatible with the NGD insert style. It is well-suited for precision external grooving on production turning equipment in both job shop and high-volume manufacturing environments. The KC5010 grade with PVD TiAlN coating targets steel and cast iron workpieces where consistent surface finish and dimensional accuracy are required. The left-hand orientation must be matched to an appropriate left-hand Top Notch toolholder to ensure correct insert seating and cutting geometry.

Key Features

• Solid carbide construction in Kennametal KC5010 grade for wear resistance in steel and cast iron
• PVD-applied TiAlN coating for thermal resistance and extended tool life at higher cutting speeds
• 0.125-inch (3.18 mm) cutting width with a maximum depth of cut of 0.250 inch (6.35 mm)
• Positive 10-degree rake angle with K chip breaker for controlled chip evacuation
• 0.0075-inch (0.19 mm) corner radius for controlled edge geometry on grooving profiles
• Left-hand insert orientation for use in matching Top Notch series toolholders

Compatibility

Designed for use in Top Notch series grooving toolholders accepting the NGD insert style. Insert size is 3125. Verify toolholder hand orientation matches this left-hand insert before installation.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist or tooling technician following the toolholder manufacturer's torque and clamping procedures. Power down and lock out the machine spindle before changing inserts. Do not reuse visibly chipped or worn inserts, as degraded cutting edges increase the risk of workpiece damage and unpredictable chip behavior. Confirm that the toolholder clamp mechanism fully engages the Top Notch insert pocket before returning the machine to service.
