Seco 02960469 Turning Insert CNMG543-MR7 TP2501 Carbide

Product Description

The SECO 02960469 is a CNMG543-MR7 indexable turning insert in grade TP2501, designed for productive metal cutting in CNC turning centers and manual lathes. The insert features a CVD-applied Duratomic multilayer coating — TiCN, Al2O3, and Cr — over a solid carbide substrate, delivering wear resistance and thermal stability at elevated cutting speeds. With an 80-degree diamond shape, negative rake geometry, and T-Land cutting edge style, it handles interrupted and continuous cuts on steel and similar materials. The MR7 chip breaker controls chip flow across a wide range of depths. The insert seats via clamp, pin, or lever-lock toolholders and is installed by machinists and CNC tooling technicians.

This insert is rated primarily for steel (ISO P grade) and is suited for secondary workpiece materials including stainless steel and cast iron. Multi-use application coverage spans turning, facing, and boring operations. The 4-cutting-edge design maximizes cost-per-edge efficiency in production environments. The CNMG-MR7 series targets general-purpose through medium-roughing passes on P10, P20, P30, and P35 material grades, making it a practical choice for job shop and production turning where a single insert geometry handles varied steel alloy types without a toolholder change.

Key Features

• CVD Duratomic multilayer coating: TiCN, Al2O3, Cr for extended tool life on steel
• MR7 chip breaker geometry with T-Land cutting edge for reliable chip control
• 4 cutting edges per insert — maximizes cost efficiency in production turning
• Negative rake, 80-degree diamond shape handles continuous and interrupted cuts
• Compatible with clamp, pin, and lever-lock insert holding methods
• Multi-use geometry covers turning, facing, and boring without toolholder swap

Compatibility

Fits CNMG-style toolholders with clamp, pin, or lever-lock holding methods. ISO code CNMG160612-MR7; industry standard number CNMG543-MR7. Meets ANSI and ISO insert standards. Designed for use with P10, P20, P30, and P35 material grades.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Ensure the machine spindle is stopped and the toolholder is fully secured in the turret before indexing or replacing the insert. Use the correct torque key for the insert screw or lever-lock mechanism as specified by the toolholder manufacturer. Inspect the insert seat and shim for debris before seating a new edge to ensure consistent tool height.
