Kennametal 1868421 CNGP431 KC5010 Carbide Turning Insert

Product Description

The KENNAMETAL 1868421 is a solid carbide turning insert in the CNGP431 industry standard configuration, part of the KENLOC series. Finished with a PVD-applied TiAlN coating and a KC5010 manufacturer grade, this insert is engineered for high wear resistance across a range of workpiece materials. It features an 80-degree diamond (rhombic) shape, a neutral hand orientation, and a honed cutting edge style. The insert measures 12.9 mm in length with a 0.5-inch inscribed circle and a 1/64-inch corner radius. It is suited for medium machining operations and carries four usable cutting edges per insert, improving cost efficiency per cutting cycle. Machinists and CNC operators install this insert in compatible KENLOC toolholders.

This insert is rated for turning, facing, and boring operations. Its primary workpiece material designations are Steel (P), Stainless Steel (M), and Superalloys and Titanium (S), with secondary applicability to Cast Iron (K) and non-ferrous materials (N). The KC5010 grade provides high wear resistance with moderate toughness, making it well suited for continuous and semi-interrupted cuts in demanding production environments. The maximum depth of cut is 1.25 mm (0.0492 inches). It is held in the toolholder by clamp and pin methods and conforms to both ANSI and ISO standards.

Key Features

• TiAlN coating applied by PVD process for elevated wear resistance at high cutting temperatures
• 80-degree diamond (rhombic) insert shape for versatile turning, facing, and boring applications
• Four cutting edges per insert for extended service life per unit
• Neutral hand orientation compatible with standard KENLOC toolholder setups
• Honed cutting edge style reduces microchipping on difficult-to-machine alloys
• Conforms to ANSI and ISO standards; ANSI code CNGP431, ISO code CNGP120404

Compatibility

Designed for use in KENLOC series toolholders that accept CNGP-style inserts with clamp and pin holding. Compatible with ANSI insert code CNGP431 and ISO insert code CNGP120404 toolholder seats.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or replacing inserts. Ensure the insert pocket and seating surface are clean and free of chips before clamping. Do not exceed the toolholder manufacturer's recommended clamping torque for the clamp and pin assembly.
