Kennametal 1114822 Grooving Insert NR3062K KC850 Carbide

Product Description

The KENNAMETAL 1114822 is a solid carbide grooving insert designed for precision external grooving and turning operations on CNC lathes and turning centers. This left-hand insert carries the KC850 grade designation and features a CVD-applied multilayer coating of TiC, TiCN, and TiN for wear resistance and extended tool life across a range of workpiece materials. The insert delivers a 3.18 mm cutting width with a maximum depth of cut of 3.81 mm and a full-radius corner profile with a 1.59 mm corner radius. It belongs to the Top Notch series and is installed and replaced by machinists and CNC setup technicians in production and job shop environments.

This insert is suited for grooving operations on ferrous and non-ferrous materials where consistent groove width and controlled chip evacuation are required. The K chip breaker geometry combined with a 10-degree positive rake angle supports lower cutting forces and cleaner chip formation. It is rated for material grades C5 and C6, making it appropriate for applications involving cast iron, steel, and similar materials at moderate to high cutting speeds.

Key Features

• CVD multilayer coating: TiC, TiCN, and TiN for improved wear and heat resistance
• Full radius corner profile with 1.59 mm corner radius for consistent groove geometry
• Positive rake angle of 10 degrees reduces cutting forces
• K chip breaker geometry promotes controlled chip formation
• Left-hand insert orientation for appropriate toolholder compatibility
• Top Notch series design for secure, repeatable seating in compatible toolholders

Compatibility

Designed for use in Top Notch series toolholders compatible with NR-style inserts. Verify toolholder insert style and hand orientation before installation.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Power down and lock out the machine before changing inserts. Use the appropriate torque wrench and insert clamp hardware specified by the toolholder manufacturer when securing the insert. Inspect the toolholder pocket for wear or debris before seating the replacement insert.
