Seco 03272964 Milling Insert SEEX1204AFTN-M14 MP2501 Carbide

Product Description

The SECO 03272964 is a solid carbide milling insert carrying the ANSI/ISO designation SEEX1204AFTN-M14 in manufacturer grade MP2501. This square-shaped, single-sided insert features a 90-degree included angle, a positive rake geometry with a 5-degree rake angle, and a T-Land cutting edge style. The 20-degree relief angle and fine-grain carbide substrate support stable cutting performance across a range of workpiece materials. A CVD-applied Duratomic coating combining TiCN and Al2O3 layers provides wear resistance and thermal stability. The insert measures 0.5 inches in length and width, with a thickness of 0.1874 inches and a 0.5-inch inscribed circle. Four cutting edges are available per insert, and the screw-hold mounting method is standard for this style.

This insert is designed for milling applications on steel as the primary workpiece material, with secondary suitability for stainless steel, cast iron, superalloys, and titanium. The M14 chip breaker geometry supports a maximum depth of cut of 0.3425 inches (6.00 mm), making it appropriate for moderate to aggressive face and shoulder milling in production environments. It is compatible with the R220.53-12 cutter series. Typical users include CNC machinists and tooling specialists in job shops, aerospace, energy, and general manufacturing operations.

Key Features

• CVD Duratomic coating (TiCN plus Al2O3) for wear resistance and thermal stability
• Fine-grain solid carbide substrate in MP2501 grade for toughness across varied materials
• Four usable cutting edges per insert for cost-efficient tooling rotation
• Positive rake (5 degrees) with T-Land edge style reduces cutting forces on the workpiece
• M14 chip breaker geometry supports maximum depth of cut of 0.3425 inches (6.00 mm)
• Neutral hand orientation for flexible cutter body application
• Screw-hold mounting for secure, repeatable seating in compatible tool bodies

Compatibility

Designed for use with SECO R220.53-12 series cutter bodies. ANSI and ISO code SEEX1204AFTN-M14 confirms fitment. Verify cutter body pocket specifications before installation to confirm proper seat geometry and screw thread compatibility.

Installation Notes

Installation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and manufacturer-specified insert screw to seat the insert firmly without overtorquing the clamping screw. Inspect the insert pocket for debris, wear, or damage before seating a new insert.
