Seco 03272857 Milling Insert XOMX120404TR-MD13 MP1501

Product Description

The SECO 03272857 is a solid carbide milling insert identified by ANSI and ISO code XOMX120404TR-MD13, manufactured to the MP1501 grade. It carries a CVD-applied Duratomic TiCN and Al2O3 coating for wear resistance during interrupted and continuous cuts. The parallelogram-shaped insert features a positive rake angle of 14.6 degrees, a T-Land cutting edge style, and two cutting edges per insert. With a maximum depth of cut of 5.80 mm and an inscribed circle diameter of 8.20 mm, it is suited to medium-to-aggressive face and shoulder milling passes. Screw-in mounting holds the insert securely in compatible toolholders.

This insert is designed primarily for steel machining and also performs in cast iron and hard material applications. It is a single-sided, right-hand insert intended for use in CNC machining centers and manual milling machines equipped with compatible cutter bodies. Typical users include machinists and tooling technicians running production or job-shop operations where controlled chip formation and edge life on ferrous workpieces are priorities. The MD13 chip breaker geometry assists with chip control across a range of feed rates and depths common in steel and cast iron finishing and semi-finishing operations.

Key Features

• Solid carbide fine-grain substrate with CVD Duratomic TiCN and Al2O3 coating for extended tool life
• Positive rake angle (14.6 degrees) and T-Land edge style reduce cutting forces on ferrous materials
• MD13 chip breaker geometry optimized for steel, cast iron, and hard material applications
• Two cutting edges per insert for cost efficiency in high-volume milling
• Maximum depth of cut of 5.80 mm supports semi-finishing and finishing passes
• Right-hand, single-sided parallelogram geometry with screw-in insert holding method

Compatibility

Compatible with SECO cutter series R217.69-12 and R220.69-12 as specified by the manufacturer. Insert size code 120404 corresponds to the XOMX-12 series toolholder family.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torque screwdriver or Torx key specified by the toolholder manufacturer when tightening the clamping screw — do not overtighten, as this can fracture the carbide insert body. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
