Seco 03095593 TNMG544-MR7 TP3501 Carbide Turning Insert

Product Description

The SECO 03095593 is a solid carbide TNMG-style turning insert with grade TP3501, designed for general turning operations in metalworking and machining applications. It features a 60-degree triangular insert shape with a neutral hand orientation and a TiCN and Al2O3 CVD Duratomic coating that extends tool life when cutting steel and stainless steel. The MR7 chip breaker geometry is optimized for medium roughing work, and the T-Land cutting edge style adds edge strength. With six usable cutting edges and a 0.063-inch corner radius, this insert delivers consistent performance across facing, back turning, boring, and standard turning passes. Licensed machinists and CNC operators handling P20, P30, and P40 material grades will find this insert well suited to production environments.

This insert is primarily intended for turning steel and stainless steel workpieces in production machining environments. It fits standard TNMG toolholders with clamp, pin, or lever lock holding methods. Typical applications include external turning, facing, and boring operations on CNC lathes and manual engine lathes. The MR7 chip breaker geometry supports medium feed rates and moderate depths of cut up to 0.929 inches, making it appropriate for roughing and semi-finishing passes in job-shop and production settings.

• Six usable cutting edges per insert for reduced per-edge tooling cost
• Neutral hand orientation fits both left-hand and right-hand TNMG toolholders
• T-Land cutting edge style provides added edge strength at higher feed rates
• Compatible with clamp, pin, and lever lock insert holding methods

Compatibility

Designed for use in TNMG-style toolholders accepting a 5/8-inch inscribed circle triangular insert with a 0.250-inch hole diameter. Conforms to ANSI and ISO standards; ISO designation TNMG270616-MR7. Suitable for P20, P30, and P40 material grades per ISO classification.

Installation Notes

Insert seating and clamping should be performed with the machine powered down and the spindle locked. Ensure the insert pocket and seating surfaces are clean and free of chips before seating the insert. Use the correct torque wrench and manufacturer-recommended clamping hardware for the toolholder style in use. Inspect the cutting edge and chip breaker for damage before each use; do not continue running a chipped or fractured insert.
