Seco 74017144 Milling Insert SEKR1203AFTN-ME13 T25M Carbide

Product Description

The SECO 74017144 is a solid carbide milling insert carrying the ANSI/ISO designation SEKR1203AFTN-ME13 in manufacturer grade T25M. This single-sided, square-shaped insert is CVD-coated with TiCN for wear resistance in demanding cutting applications. It features a positive rake geometry at 25.5 degrees, a T-Land cutting edge style, and a 20-degree relief angle. With four usable cutting edges and a wedge-clamp holding method, the insert is engineered for face milling and shoulder milling operations where consistent chip control and edge life are required. It is sized to the 1203 insert size code, with a 0.5000-inch inscribed circle and a thickness of 0.1252 inches.

This insert is suited for machining steel, stainless steel, superalloys, and titanium, covering ISO material application codes P, M, and S. It performs in both roughing and semi-finishing passes where a positive cutting geometry and controlled chip formation are priorities. The ME13 chip breaker geometry is designed for medium-grain carbide grades running at moderate-to-aggressive feed rates in these material groups. Licensed machinists and CNC setup technicians working in production environments or job shops will find this insert appropriate for turning centers and milling fixtures requiring SEKR-12 series tooling.

Key Features

• Solid carbide construction with CVD-applied TiCN coating for extended tool life
• Square insert shape with 90-degree included angle and neutral hand orientation
• Four cutting edges per insert for cost-efficient indexing
• Positive rake angle of 25.5 degrees with T-Land cutting edge style for clean entry into workpiece material
• Maximum depth of cut of 0.3465 inches and effective cutting edge length of 0.5000 inches
• ME13 chip breaker optimized for steel, stainless steel, superalloys, and titanium

Compatibility

Compatible with cutter series R220.13-12. ANSI and ISO designation SEKR1203AFTN-ME13 confirms fitment in toolholders and milling cutter bodies designed for the SEKR-12 insert series using a wedge-clamp holding method.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool is secured in a holder before indexing or replacing inserts. Use the correct torque driver for the wedge clamp to avoid insert rocking or premature edge failure. Confirm insert seating in the pocket before resuming cutting operations.
