Seco 03276595 TCMT32.51-F1 TM2501 Turning Insert Carbide

Product Description

The SECO 03276595 is a TCMT-style triangular turning insert designed for precision metal cutting on CNC and manual lathes. Manufactured from solid carbide and coated with a CVD-applied TiCN, Al2O3, and Cr Duratomic multilayer finish, this insert delivers wear resistance and thermal stability in demanding machining environments. The F1 chip breaker geometry produces a sharp cutting edge with a positive 17-degree rake angle, making it well suited for finishing and semi-finishing passes. The insert measures 39/64 inches in length with a 3/8-inch inscribed circle and a 1/64-inch corner radius. It features a neutral hand orientation, three usable cutting edges, and a screw-type holding method for secure tool post retention.

This insert is primarily rated for stainless steel (ISO material code M) and secondarily for general steel (ISO material code P), covering material grades M25, M30, and M35. It is appropriate for multi-use turning operations including back turning, boring, facing, and standard OD turning. The F1 chip breaker is optimized for lighter depths of cut and controlled chip formation on work-hardening alloys. Licensed machinists and CNC operators in job shop, production, and maintenance machining environments are the typical end users. The ISO designation for this insert is TCMT16T304-F1, and it conforms to both ANSI and ISO tooling standards.

Key Features

• CVD Duratomic TiCN, Al2O3, and Cr multilayer coating for extended tool life on stainless and steel
• F1 chip breaker with sharp cutting edge geometry and positive 17-degree rake angle
• Three usable cutting edges per insert for cost-effective tooling management
• Screw-type insert holding method compatible with standard TCMT toolholders
• Rated for back turning, boring, facing, and turning applications
• Conforms to ANSI and ISO standards; ISO code TCMT16T304-F1

Compatibility

Designed for use in standard TCMT-series screw-on toolholders conforming to ANSI and ISO mounting specifications. Suitable for CNC turning centers and manual lathes equipped for TCMT32.51 insert geometry. Verify toolholder pocket dimensions against the 0.1772-inch hole diameter and 5/32-inch insert thickness before installation.

Installation Notes

Installation is performed by machining professionals using standard TCMT toolholders and the appropriate Torx or hex drive screw for the insert pocket. Power down and lock out the machine spindle before seating or indexing the insert. Inspect the insert pocket and clamping screw for wear or debris before seating a new edge. Do not exceed the maximum depth of cut of 0.6110 inches as specified for this insert geometry.
