Seco 03273007 Milling Insert MP2501 Solid Carbide Octagon

Product Description

The SECO 03273007 is a solid carbide milling insert in the ONMU-09 series, designed for high-productivity face and shoulder milling operations. It features a fine-grain carbide substrate coated via CVD with a TiCN and Al2O3 Duratomic multilayer coating for extended wear resistance and thermal stability. The octagon insert shape delivers 16 usable cutting edges per insert, reducing tooling cost per edge. With a negative rake angle of 15 degrees and a T-Land cutting edge style, this insert is built for aggressive material removal on steel and related workpiece materials. Installation and use require a compatible milling cutter body.

This insert is suited for milling applications in steel as its primary workpiece material, with rated capability in stainless steel, cast iron, superalloys, and titanium. The neutral hand orientation makes it adaptable across a range of face milling setups. It carries ISO material grade codes P, M, K, and S, covering a broad spectrum of CNC machining environments in both production and job-shop settings. Machining technicians and CNC programmers working with demanding alloy families will find this insert appropriate for moderate to heavy depth-of-cut passes.

Key Features

• 16 cutting edges per insert from double-sided octagon geometry, maximizing value per insert
• CVD-applied TiCN and Al2O3 Duratomic coating for heat and abrasion resistance
• Fine-grain solid carbide substrate for edge integrity under high cutting forces
• Negative rake at 15 degrees with T-Land edge prep for strength on interrupted cuts
• Maximum depth of cut of 0.3031 inches with a cutting edge effective length of 0.3031 inches
• Compatible with R220.48-09 and L220.48-09 cutter series bodies

Compatibility

Designed for use with R220.48-09 and L220.48-09 cutter series bodies. ANSI and ISO code: ONMU090520ANTN-M15. Chip breaker designation M15. Suitable for steel, stainless steel, cast iron, superalloys, and titanium workpiece materials per ISO material codes P, M, K, and S.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians using the screw-holding method specified for the ONMU-09 insert seat. Ensure the milling cutter body is fully powered down and spindle is locked before seating or replacing inserts. Use the correct torx or hex key to the cutter manufacturer torque specification shown in the cutter body documentation. Inspect the insert pocket seating surface for chips or debris before installation to prevent insert rocking and premature edge failure.
