Seco 02960571 SNMG644-M5 TP2501 Turning Insert Carbide

Product Description

The SECO 02960571 is a solid carbide turning insert in the SNMG-M5 series, designed for general turning, facing, and boring operations on CNC lathes and turning centers. The insert carries a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr, which provides thermal resistance and wear protection during continuous and interrupted cuts. It features a 90-degree square shape with a negative rake angle, a 0.75 inch inscribed circle, a 0.063 inch corner radius, and 8 usable cutting edges. The M5 chipbreaker geometry suits medium-duty material removal on steel and related workpiece materials. Licensed machinists and CNC operators in production shops are the primary installers and users of this insert.

This insert is engineered for primary use on steel workpieces classified under ISO material group P, covering low-alloy and carbon steel. Secondary applications include stainless steel (ISO group M) and cast iron (ISO group K). Material grades P10, P20, P30, and P35 are cited for this insert, spanning a range from finishing to medium roughing operations. Multi-use capability covers boring, facing, and turning in a single insert style, reducing tooling inventory requirements in mixed-operation environments. The M5 chipbreaker is suited to medium feeds and depths of cut up to 0.687 inches.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for extended tool life on steel
• 8 cutting edges per insert reduces per-edge cost in high-volume turning
• M5 chipbreaker geometry optimized for medium-duty steel machining
• Negative rake, 90-degree square geometry compatible with clamp, pin, and lever lock holding methods
• Maximum depth of cut of 0.687 inches supports medium roughing passes
• Chamfered and honed cutting edge style improves edge stability and reduces micro-chipping
• Complies with ANSI and ISO standards; ISO code SNMG190616-M5

Compatibility

Designed as an OEM-style replacement or direct-fit insert for toolholders accepting SNMG-style inserts with a 0.75 inch inscribed circle, 0.25 inch thickness, and a 0.3118 inch hole diameter, using clamp, pin, or lever lock holding methods per ANSI and ISO standards.

Installation Notes

Installation is performed by licensed machinists or CNC tooling technicians. Power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket locating surfaces before tightening the clamping hardware to prevent insert rocking or shifting during cutting. Inspect the insert pocket and seating surfaces for chips or debris before seating a fresh edge.
