Seco 02956309 Turning Insert CCMT32.52-MF2 TP2501 Carbide

Product Description

The SECO 02956309 is a solid carbide turning insert in the CCMT32.52-MF2 series, designed for external and internal turning, facing, and boring operations on CNC and manual lathes. It features a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — over a carbide substrate graded TP2501. The insert has an 80-degree diamond shape, a 3/8-inch inscribed circle, a 1/32-inch corner radius (0.0315 inches), and a neutral hand orientation. With 2 cutting edges and a positive rake geometry paired with the MF2 chip breaker, it is engineered for light-to-medium cutting passes on steel and stainless steel. Machinists and CNC operators in production shops are the primary users.

This insert is suited for finish to semi-finish turning applications where chip control and surface finish quality are critical. Primary workpiece material is steel (ISO code P), with secondary suitability for stainless steel (M) and cast iron (K). It fits standard CCMT screw-on toolholders and is applicable across boring bars, external turning holders, and facing operations. The MF2 chip breaker geometry is optimized for light feeds and smaller depths of cut, making this insert a common choice for tight-tolerance finish passes on P10 through P35 grade steel workpieces. ISO designation for this insert is CCMT09T308-MF2.

Key Features

• CVD Duratomic multilayer coating (TiCN, Al2O3, Cr) for extended tool life on steel and stainless
• MF2 chip breaker geometry optimized for finish to semi-finish cutting with positive rake
• 80-degree diamond insert shape (ISO shape code C) with chamfered and honed cutting edge
• 2 usable cutting edges per insert for cost-effective indexing
• Screw-on insert holding method compatible with standard CCMT toolholders
• Multi-use application: turning, facing, and boring from a single insert style

Compatibility

Designed for use in standard CCMT screw-clamped toolholders conforming to ANSI and ISO specifications. ISO designation CCMT09T308-MF2 cross-references directly to industry-standard holder pockets sized for the CCMT32.52 insert family. Verify toolholder pocket geometry, screw size, and shim requirements before installing.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Before indexing or replacing the insert, ensure the machine spindle is fully stopped and all axis motion is disabled. Seat the insert fully against the pocket locating surfaces before tightening the clamping screw to avoid micro-movement during cutting. Inspect the toolholder pocket and shim for wear, chips, or debris that could affect insert seating and runout.
