Seco 02959847 CNMG432-M6 Turning Insert TP1501 Carbide

Product Description

The SECO 02959847 is a CNMG432-M6 indexable turning insert in the Seco Duratomic TP1501 grade, designed for high-productivity metal cutting on CNC lathes and turning centers. This multi-tipped carbide insert features an 80-degree diamond shape (C insert shape code), a neutral hand orientation, and a 1/2-inch inscribed circle with a 1/32-inch corner radius. The CVD-applied Duratomic coating stack — TiCN, Al2O3, and Cr — delivers thermal resistance and wear life across a wide range of cutting conditions. With four usable cutting edges per insert, this geometry supports boring, facing, and turning operations.

This insert is suited to general and semi-finish turning of steel and cast iron in both residential shop and production floor environments. The M6 chip breaker geometry controls chip formation across moderate depths of cut up to 0.4764 inches, making it appropriate for medium-duty passes on steel workpieces classified under ISO P10 and P20 material grades. Secondary workpiece materials include cast iron and hard materials. Installed by CNC machinists and toolroom professionals in CNMG-compatible toolholders that accept clamp, pin, or lever-lock insert-holding methods.

Key Features

• Duratomic CVD coating (TiCN, Al2O3, Cr) for extended tool life in steel and cast iron cutting
• 80-degree diamond insert shape with neutral hand — versatile for boring, facing, and turning
• Four cutting edges per insert reduce per-edge tooling cost
• M6 chip breaker geometry manages chip control at moderate depths of cut
• Honed cutting edge style reduces micro-chipping on interrupted and continuous cuts
• Conforms to ANSI and ISO standards (ISO code CNMG120408-M6)

Compatibility

Designed for CNMG-style toolholders that accept clamp, pin, or lever-lock holding methods with a 0.2028-inch hole diameter. Compatible with applications targeting ISO P-class (steel) primary workpiece materials and K-class (cast iron) and H-class (hard material) secondary workpiece materials. Industry standard number CNMG432-M6 applies.

Installation Notes

Insert installation and indexing should be performed by a qualified machinist with the machine fully powered down and all axes at a safe position. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer — do not overtighten the clamping screw, as this can fracture the carbide substrate. Inspect the insert seat and chip pocket for debris before seating each new cutting edge. Confirm insert orientation and hand designation match the toolholder before resuming cuts.
