Kennametal 5882268 CNMG432MN KCP30B Turning Insert

Product Description

The KENNAMETAL 5882268 is a CNMG432MN-style indexable turning insert in the KENLOC series, coated with a multilayer CVD TiN/TiCN/Al2O3/TiOCN stack under the grade designation KCP30B. The insert features an 80-degree diamond shape with a neutral hand orientation, a 0-degree rake angle, and a chamfered and honed cutting edge. It measures 12.9 mm (0.5077 inches) in length with a 1/2-inch inscribed circle and a 1/32-inch corner radius. The insert is held by clamp and pin and is designed primarily for turning steel workpieces. Machinists and CNC operators working in steel-focused production environments are the primary installers and users.

This insert is suited for external turning, facing, and boring operations, primarily on steel (ISO material group P, material grades C5 and C6). It carries an industry-standard designation of CNMG432MN and an ISO code of CNMG120408MN, making it a direct fit in any CNMG-compatible toolholder that accepts the 432 insert size. The MN chipbreaker geometry is optimized for steel cutting at moderate to aggressive depths of cut, with a maximum depth of cut of 0.1691 inches. Both ANSI and ISO standards are met.

Key Features

• Multilayer CVD coating: TiN / TiCN / Al2O3 / TiOCN for wear resistance on steel
• KCP30B grade engineered for steel turning with consistent tool life
• 80-degree diamond insert shape (CNMG) with 4 cutting edges for cost-per-edge efficiency
• MN chipbreaker geometry with chamfered and honed edge for controlled chip flow
• Neutral hand orientation allows use in a wide range of toolholder setups
• Compatible with clamp and pin holding methods for secure seating under load

Compatibility

Designed for use in CNMG432-compatible KENLOC-series toolholders and any industry-standard CNMG toolholder accepting the 432 insert size. Industry standard number CNMG432MN and ISO code CNMG120408MN confirm cross-reference fitment. Rated for turning, facing, and boring of steel workpieces in ISO P material group applications.

Installation Notes

Installation is performed by a machinist or CNC tooling technician. Before seating or indexing the insert, power down and lock out the machine spindle per facility LOTO procedures. Ensure the insert pocket and clamp surfaces are clean and free of chips before seating. Use the appropriate torx or clamp screw to secure the insert per the toolholder manufacturer's seating procedure — do not overtighten by feel alone; follow toolholder documentation for fastener guidance.
