Seco 03273000 Milling Insert ONMU050410ANTN-M10 MP2501

Product Description

The SECO 03273000 is a solid carbide, double-sided octagonal milling insert carrying the ANSI/ISO designation ONMU050410ANTN-M10 and manufactured in the MP2501 grade. The insert features a CVD-applied Duratomic coating of TiCN and Al2O3 that extends tool life in demanding milling operations. With 16 available cutting edges, a neutral hand orientation, and a negative rake geometry with a T-Land cutting edge style, it is engineered for high-productivity face and shoulder milling. Licensed machinists and CNC mill operators install this insert in compatible milling cutter bodies where consistent edge life and multi-material capability are required.

This insert is suited for milling steel as its primary workpiece material, with secondary suitability for stainless steel, cast iron, and superalloys and titanium. It fits the SECO R217.48-05 and R220.48-05 cutter series. Typical applications include roughing and semi-finishing passes on ferrous and difficult-to-machine alloys in industrial machining environments. The M10 chip breaker geometry supports controlled chip evacuation across the listed material grades. The insert is sold individually but carries a minimum order quantity of 10 units.

Key Features

• 16 cutting edges per insert on a double-sided octagon body, reducing cost per edge
• CVD Duratomic coating (TiCN plus Al2O3) for wear resistance on steel and stainless steel
• MP2501 fine-grain carbide grade rated for steel, stainless steel, cast iron, and superalloys and titanium
• M10 chip breaker for effective chip control across a broad range of materials
• Neutral hand with negative rake and T-Land edge style for stable, predictable cutting action
• Screw-lock insert holding method for secure seating in compatible cutter bodies

Compatibility

Designed for use in SECO cutter series R217.48-05 and R220.48-05. Verify cutter body pocket geometry and screw specification before installation. Compatible with ANSI/ISO insert seat designation ONMU050410ANTN-M10.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Always power down and lock out the machine spindle before seating or removing inserts. Use the correct torque wrench and manufacturer-specified clamping screw for the cutter body to avoid insert cracking or seat damage. Inspect the pocket seat and clamping screw for wear or contamination before installing a new insert.
