Seco 02959846 CNMG432-M6 Turning Insert Carbide TP0501

Product Description

The SECO 02959846 is a CNMG432-M6 series indexable turning insert designed for general-purpose metal cutting operations. It is manufactured from solid carbide and finished with a multi-layer CVD coating consisting of TiCN, Al2O3, and Cr under SECO's Duratomic coating classification. The insert features an 80-degree diamond shape, a negative rake geometry, and a honed cutting edge. With a 1/2-inch inscribed circle, a corner radius of 0.0315 inches, and four available cutting edges, this insert suits medium to general turning applications in production environments. It is typically installed by machinists and tool-room technicians working with CNC lathes and turning centers.

This insert is suited for primary use on steel workpieces (ISO material code P, material grades P01 and P10) and secondary use on cast iron (ISO material code K). Applicable operations include turning, facing, and boring. The M6 chip breaker geometry is designed for medium cutting conditions on these material groups. The insert carries the ISO designation CNMG120408-M6 and the industry standard number CNMG432-M6, and it conforms to both ANSI and ISO standards. It is sold individually with a minimum order quantity of 10.

Key Features

• CVD-applied Duratomic coating (TiCN, Al2O3, Cr) for thermal resistance and wear performance on steel and cast iron
• 80-degree diamond insert shape (CNMG) with negative rake and honed cutting edge for edge strength
• Four cutting edges per insert for extended tool life and reduced per-edge cost
• M6 chip breaker geometry suited to medium-depth turning, facing, and boring operations
• Maximum depth of cut of 0.4764 inches with an inscribed circle of 0.5000 inches
• Compatible with clamp, pin, and lever-lock insert-holding methods for toolholder flexibility

Compatibility

Designed for use in CNMG-style toolholders that accept clamp, pin, or lever-lock holding methods. Compatible with standard CNMG432 insert seats conforming to ANSI and ISO tolerances. Suitable for use on steel and cast iron workpieces. Verify toolholder seat specifications before installation.

Installation Notes

Installation is performed by machinists using standard insert-clamping tools appropriate to the toolholder style (clamp, pin, or lever lock). Ensure the machine spindle is fully stopped and the turret is indexed away from the cutting zone before changing inserts. Inspect the insert pocket and seating surface for chips or debris before seating the new insert. Follow the toolholder manufacturer's clamping torque specifications for the specific holder in use.
