Seco 02956311 CCMT432-MF2 TP2501 Turning Insert Carbide

Product Description

The SECO 02956311 is a solid carbide turning insert in the CCMT432-MF2 series, designed for precision metal cutting in CNC and manual turning applications. It features an 80-degree diamond shape with a neutral hand orientation and a 0.0315 inch corner radius. The insert carries a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — classified under manufacturer grade TP2501. With a 0.5 inch inscribed circle and two cutting edges, it delivers consistent chip control through the MF2 chip breaker geometry, which is optimized for light to medium finishing passes on steel and stainless steel. A licensed machinist or CNC operator typically installs and indexes this insert.

This insert is suited for facing, boring, and turning operations on steel, stainless steel, and cast iron workpieces. It is rated for material grades P10, P20, P30, and P35 under the ISO P and M classification system. The positive rake geometry and chamfered-and-honed cutting edge reduce cutting forces during finishing cuts, making it a practical choice for both light roughing and fine finishing in production turning environments. It is screw-held in compatible CCMT-style toolholders and indexed when a cutting edge dulls.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for wear resistance on steel and stainless
• 80-degree diamond insert shape with positive rake for reduced cutting forces
• MF2 chip breaker geometry optimized for light to medium finishing passes
• Two usable cutting edges per insert; screw-held retention in CCMT toolholders
• Chamfered and honed cutting edge style for edge stability and surface finish quality
• Compatible with facing, boring, and turning multi-use applications

Compatibility

Designed as a screw-held replacement insert for CCMT-style toolholders accepting a size 432 insert. Conforms to ANSI and ISO standards; ISO equivalent designation is CCMT120408-MF2. Primary workpiece material is steel (ISO P); secondary workpiece materials are stainless steel (ISO M) and cast iron (ISO K).

Installation Notes

Insert indexing and replacement is performed by a qualified machinist or CNC tooling technician. Always power down and lock out the machine spindle before accessing the toolholder. Use the appropriate torx or hex key for the clamping screw specified by the toolholder manufacturer — do not overtighten. Inspect the insert pocket for chips or burrs before seating a new insert, and confirm the edge is fully indexed before resuming cuts.
