Seco 02956328 Turning Insert CCMT32.51-M5 TP2501 Carbide

Product Description

The SECO 02956328 is a solid carbide turning insert designed for precision metal cutting in CNC and manual turning applications. Identified by industry standard number CCMT32.51-M5 and ISO code CCMT09T304-M5, this insert features an 80-degree diamond shape with a 7-degree relief angle and a neutral hand orientation. The TP2501 grade uses a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — engineered for controlled wear resistance and thermal stability. With a 3/8-inch inscribed circle and a 1/64-inch corner radius, it delivers consistent chip control across roughing and finishing passes. The M5 chip breaker geometry and chamfered-and-honed cutting edge style suit a wide range of depths and feed rates on ferrous materials.

This insert is used in turning, boring, and facing operations on CNC lathes and turning centers. Its primary target workpiece material is steel, with secondary suitability for stainless steel and cast iron. Material grades P10, P20, P30, and P35 cover a broad spectrum of steel hardness and alloy content. The screw-on holding method makes it compatible with standard CCMT-style toolholders. It is a multi-tipped insert with 2 cutting edges, extending usable life before replacement. Machinists, tooling specialists, and CNC programmers in metalworking shops are the typical end users.

Key Features

• CVD Duratomic coating — TiCN, Al2O3, and Cr layers — for thermal resistance and extended tool life on steel
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• M5 chip breaker geometry supports boring, facing, and turning in a single insert style
• 2 cutting edges per insert; screw-on holding method for repeatable positioning
• Chamfered and honed cutting edge style for edge toughness on interrupted and continuous cuts
• Meets ANSI and ISO standards; ISO code CCMT09T304-M5 for cross-reference ordering

Compatibility

Designed as an OEM-style replacement for CCMT-style toolholders accepting the CCMT32.51 insert size. Compatible with steel, stainless steel, and cast iron workpieces across material grades P10, P20, P30, and P35. Cross-references to ISO code CCMT09T304-M5.

Installation Notes

Installation is performed by tooling technicians or CNC machinists using the screw-on holding method standard to CCMT toolholder blocks. Ensure the toolholder pocket and seating surfaces are clean and free of chips before seating the insert. Torque the clamping screw to the toolholder manufacturer's specified value — do not estimate. Index or replace the insert when flank wear or edge chipping affects surface finish or dimensional tolerance.
