Seco 03272987 Milling Insert OFEX05T305TN-D09 MP1501

Product Description

The SECO 03272987 is a solid carbide milling insert in the OFEX-05 series, identified by ANSI and ISO code OFEX05T305TN-D09 and manufactured to grade MP1501. The insert features an octagon shape with 8 cutting edges, a neutral rake and neutral hand orientation, and a T-Land cutting edge style. It carries a CVD-applied Duratomic coating combining TiCN and Al2O3 layers, delivering wear resistance and thermal stability in demanding milling applications. Thickness is 0.1563 inches with an inscribed circle diameter of 0.5042 inches. Licensed machinists, tooling technicians, and CNC mill operators install this insert in compatible face and shoulder milling cutter bodies.

This insert is suited for milling steel as its primary workpiece material, with secondary capability in cast iron and hard materials. The D09 chip breaker geometry supports controlled chip formation across these material groups. A maximum depth of cut of 0.1929 inches and a cutting edge effective length of 0.2079 inches define the productive engagement envelope. It is designed for industrial machining environments where consistent edge life and predictable wear progression are required. Compatible cutter series are R217.43-05 and R220.43-05.

Key Features

• Solid carbide fine-grain substrate for toughness and edge retention
• CVD Duratomic coating with TiCN and Al2O3 layers for thermal and abrasive wear resistance
• Octagon shape with 8 cutting edges maximizes cost-per-edge economy
• T-Land cutting edge style improves edge strength in interrupted and continuous cuts
• D09 chip breaker optimized for steel, cast iron, and hard material applications
• Neutral rake and neutral hand for broad cutter body compatibility
• Screw-held insert mounting for secure, repeatable indexing

Compatibility

Compatible with SECO cutter series R217.43-05 and R220.43-05. Insert size code is 05T305. Conforms to ISO standards per ANSI and ISO designation OFEX05T305TN-D09.

Installation Notes

Installation is performed by machinists or CNC tooling technicians. Power down and lock out the spindle before indexing or replacing inserts. Use the appropriate Torx or hex key as specified by the cutter body manufacturer for the clamping screw. Ensure the insert seat and screw threads are clean and free of chips before seating the insert to maintain accurate positioning and prevent premature edge failure.
