Seco 02960579 Turning Insert TNMG432-M5 TP2501 Carbide

Product Description

The SECO 02960579 is a TNMG432-M5 triangular carbide turning insert coated with a CVD-applied Duratomic multilayer coating of TiCN, Al2O3, and Cr. Manufactured to the TP2501 grade, it is designed for external and internal turning operations on steel and stainless steel in CNC lathes and turning centers. The insert carries a 0.5000-inch inscribed circle, a 0.0315-inch corner radius, and a 60-degree included angle. It features a negative rake geometry with a chamfered and honed cutting edge and the M5 chip breaker geometry, making it well-suited for general-purpose medium-stock-removal work on ferrous materials. Professional machinists and CNC operators install and index this insert.

This insert is intended for turning, facing, boring, and back-turning applications. The primary workpiece material is steel, covering material grades P10, P20, P30, and P35. Secondary workpiece materials include stainless steel and cast iron. The M5 chip breaker geometry handles a length-of-cut range from 0.7000 inch to 10.0000 inches. The insert is held by clamp, pin, or lever-lock toolholding systems, giving it broad compatibility across standard TNMG-style toolholders used in production and job-shop environments.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, and Cr for wear resistance on steel and stainless
• 6 cutting edges per insert reduces per-edge tooling cost in high-volume runs
• M5 chip breaker geometry supports turning, facing, boring, and back-turning operations
• Negative rake, chamfered and honed edge for stable cutting action and edge security
• Compatible with clamp, pin, and lever-lock toolholding systems
• Conforms to ANSI and ISO standards; ISO code TNMG220408-M5

Compatibility

Designed for use in TNMG-style toolholders that accept a 0.5000-inch inscribed-circle triangular insert with a 0.2028-inch hole diameter. Compatible with clamp, pin, and lever-lock holding methods. Suitable for steel (P10-P35), stainless steel, and cast iron workpiece materials.

Installation Notes

Insert indexing and replacement should be performed by a qualified machinist or CNC operator with the machine fully stopped and locked out per facility lockout/tagout procedures. Seat the insert fully against the pocket walls and tighten the clamping screw or lever to the toolholder manufacturer's specified torque. Inspect the insert pocket for chips or debris before seating a new edge. Verify the correct ISO or ANSI toolholder designation matches the TNMG insert geometry before running the first cut.
