Kennametal 1114899 Grooving Insert KC850 Solid Carbide

Product Description

The KENNAMETAL 1114899 is a solid carbide grooving insert designed for precision grooving operations on CNC lathes and turning centers. Cataloged under the Top Notch series, it carries the NG3062K insert style designation and is manufactured to a KC850 grade substrate with a CVD-applied multilayer coating of TiC, TiCN, and TiN. This coating stack provides wear resistance and thermal stability across a range of ferrous and non-ferrous workpiece materials. The insert delivers a 1.58 mm cutting width with a maximum depth of cut of 2.39 mm, a positive 10-degree rake angle, and a 0.19 mm corner radius. It is configured for right-hand operation and is installed and replaced by machinists and CNC tooling technicians.

This insert is suited for external grooving, parting, and profiling applications on production turning equipment. The Top Notch series tooling system is common in high-volume manufacturing environments where repeatable insert indexing and secure clamping are required. The K-style chip breaker geometry promotes controlled chip formation during shallow to mid-depth groove cuts. Material grade classifications of C5 and C6 indicate suitability for finishing to semi-finishing passes on steel and cast iron workpieces. The positive rake geometry also makes this insert applicable to lighter-duty cuts where minimizing cutting forces is a priority.

Key Features

• KC850 grade solid carbide substrate with CVD multilayer TiC, TiCN, and TiN coating for extended tool life
• 1.58 mm cutting width with a maximum depth of cut of 2.39 mm
• Positive rake angle of 10 degrees reduces cutting forces on the workpiece
• K-style chip breaker for controlled chip evacuation during grooving passes
• 0.19 mm corner radius with a 55-degree included angle for precise groove geometry
• Right-hand configuration with NG-style insert form for Top Notch compatible toolholders

Compatibility

Designed for use in Top Notch series grooving toolholders that accept NG3062-style inserts. Refer to KENNAMETAL toolholder documentation for confirmed holder compatibility before installation.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist or CNC tooling technician. Always bring the machine spindle to a complete stop and lock out the machine before changing or indexing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to seat the insert properly. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.
