Seco 03095440 CCMT32.51-M3 TP3501 Carbide Turning Insert

Product Description

The SECO 03095440 is a solid carbide turning insert in the CCMT-M3 series, designed for precision metal turning applications in CNC and manual lathe operations. It carries the industry standard designation CCMT32.51-M3 and ISO code CCMT09T304-M3. The insert features a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, which improves wear resistance and thermal stability at the cutting edge. The 80-degree diamond shape provides a strong cutting geometry, while the M3 chip breaker and chamfered and honed cutting edge style deliver controlled chip flow and consistent surface finish. With 2 cutting edges and a positive rake, this insert balances tool life with cutting efficiency on ferrous workpiece materials.

This insert is intended for boring, facing, and turning operations where steel and stainless steel are the primary workpiece materials. It is suited for material grades P20, P30, and P40, making it a practical choice for general-purpose and medium-duty machining in both production and job-shop environments. A licensed machinist or CNC tooling technician would typically install this insert in a compatible CCMT-style screw-on toolholder. The insert is sold individually with a minimum order quantity of 10 units.

Key Features

• Solid carbide substrate with CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for extended tool life
• CCMT32.51-M3 geometry with 80-degree diamond shape and 7-degree relief angle for strong edge support
• M3 chip breaker designed for controlled chip evacuation during steel and stainless steel turning
• Chamfered and honed cutting edge style reduces micro-chipping on interrupted and continuous cuts
• 2 cutting edges per insert; screw-held mounting for fast, repeatable indexing
• Multi-use application: boring, facing, and turning in a single insert geometry

Compatibility

Designed for use in CCMT-style screw-on toolholders compatible with the CCMT32.51 insert size. Primary workpiece materials are steel (ISO P) and stainless steel (ISO M), with rated material grades of P20, P30, and P40. Conforms to ANSI and ISO standards for CCMT insert geometry.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician using a compatible CCMT insert toolholder and the appropriate torx or hex drive for the clamping screw. Power down and de-energize the machine spindle before indexing or replacing the insert. Seat the insert fully against the toolholder pocket and torque the clamping screw according to the toolholder manufacturer specification. Inspect the cutting edge and chip breaker for damage before returning the tool to service.
