Seco 03272826 Milling Insert XOMX120408TR-M12 MP2501

Product Description

The SECO 03272826 is a solid carbide indexable milling insert carrying ANSI/ISO designation XOMX120408TR-M12 in manufacturer grade MP2501. It is a parallelogram-shaped, single-sided insert with a positive rake geometry and a T-Land cutting edge style designed for face and shoulder milling operations. The insert features a CVD-applied Duratomic coating — TiCN over Al2O3 — which provides thermal resistance and wear protection in interrupted and continuous cut conditions. With two cutting edges, a 15-degree relief angle, and a 10.4-degree rake angle, it is suited for productive metal removal on steel and related workpiece materials. Machinists and CNC operators in job shops and production facilities install and index these inserts during scheduled tooling changes.

This insert is intended for milling applications where the primary workpiece material is steel, with secondary suitability for stainless steel, cast iron, superalloys, and titanium (ISO material codes P, M, K, and S). The M12 chip breaker geometry supports stable chip formation across a range of feed rates. It is a right-hand insert held in the cutter body by a screw-clamp method. Typical use cases include face milling, shoulder milling, and pocketing operations on CNC machining centers. Compatible cutter series include R217.69-12 and R220.69-12 per supplier data.

Key Features

• Solid carbide fine-grain substrate with CVD Duratomic coating (TiCN plus Al2O3) for extended tool life in steel cutting
• Parallelogram insert shape with 90-degree included angle and positive rake for reduced cutting forces
• T-Land cutting edge style provides edge strength and controlled chip formation
• Two usable cutting edges per insert for cost-effective indexing
• Maximum depth of cut of 5.80 mm for productive material removal
• Right-hand orientation with screw-clamp holding method for secure seating in the cutter pocket

Compatibility

Compatible with SECO cutter series R217.69-12 and R220.69-12 as stated by the manufacturer. Insert size code 120408 conforms to ISO standard designation XOMX120408TR-M12.

Installation Notes

Insert indexing and replacement is performed by a machinist or CNC tooling technician. Power down and lock out the machine spindle before accessing the cutter body. Use the correct Torx or hex key for the cutter screw and ensure the insert seats fully and squarely in the pocket before tightening. Inspect the cutter pocket and seating surfaces for debris or damage each time an insert is indexed.
