Kennametal 1114892 Grooving Insert KC850 Solid Carbide

Product Description

The KENNAMETAL 1114892 is a solid carbide grooving insert designed for precision external grooving operations on CNC lathes and turning centers. Carrying the KC850 manufacturer grade with a CVD-applied TiC, TiCN, and TiN multilayer coating, it delivers wear resistance and thermal stability across a range of workpiece materials. The insert features a 3.18 mm cutting width, a maximum depth of cut of 3.81 mm, and a positive rake angle of 10 degrees, making it well suited for finish and semi-finish grooving passes where surface quality and dimensional accuracy matter. Licensed machinists and CNC turning specialists are the primary installers.

This insert fits the Top Notch series tooling system and is configured for right-hand cutting. It carries an insert size designation of 3125 and a chip breaker style of K, which is optimized for controlled chip formation during grooving. Material grades C5 and C6 indicate suitability for machining steels and cast irons at moderate to high cutting speeds. The 55-degree included angle and a corner radius of 0.19 mm contribute to precise groove geometry and edge definition on finished components.

Key Features

• CVD multilayer coating: TiC, TiCN, and TiN for extended tool life and heat resistance
• KC850 grade solid carbide construction for rigidity and wear resistance
• 3.18 mm cutting width with a maximum depth of cut of 3.81 mm
• Positive rake angle of 10 degrees for reduced cutting forces
• K-style chip breaker for predictable chip control during grooving
• Right-hand orientation with a 0.19 mm corner radius for precise groove geometry

Compatibility

Designed for use with the Kennametal Top Notch series grooving toolholders. The insert size designation 3125 and right-hand configuration must match the corresponding toolholder specification. Refer to Kennametal Top Notch system documentation to confirm holder compatibility before installation.

Installation Notes

Installation should be performed by a qualified CNC machinist or tooling specialist familiar with indexable insert systems. Power down and lock out the machine spindle before seating or removing inserts. Use the appropriate Torx or insert-clamp wrench specified by the toolholder manufacturer — do not use impact tools on clamping screws. Inspect the insert pocket and clamping components for debris or wear before each insert change to ensure proper seating and secure retention.
