Seco 03273260 Milling Insert SCET120630T-M14 MP2501

Product Description

The SECO 03273260 is a solid carbide milling insert carrying the ANSI/ISO designation SCET120630T-M14 in manufacturer grade MP2501. It features a square insert shape with a 90-degree included angle, four cutting edges, and a neutral hand orientation. The CVD-applied Duratomic coating combines TiCN and Al2O3 layers for extended tool life in demanding milling operations. A positive rake angle of 15 degrees and T-Land cutting edge style reduce cutting forces and improve chip evacuation. The insert is held in place by a screw and fits the R220.21-SC12 cutter series. Licensed HVAC and metalworking professionals recognize this insert for consistent performance in high-production milling environments.

This insert is suited for milling steel as its primary workpiece material, with additional application coverage for stainless steel, cast iron, superalloys, and titanium. The M14 chip breaker geometry is optimized for these material groups. It is designed for use in face milling and shoulder milling operations on CNC machining centers where controlled chip formation and thermal resistance are critical. The fine-grain carbide substrate supports higher cutting speeds without sacrificing edge integrity.

Key Features

• Solid carbide substrate with fine-grain material grade for high-speed milling stability
• CVD Duratomic coating (TiCN plus Al2O3) for wear resistance and thermal protection
• Four cutting edges per insert with neutral hand and positive 15-degree rake angle
• M14 chip breaker geometry optimized for steel, stainless steel, cast iron, superalloys, and titanium
• T-Land cutting edge style reduces chipping and improves edge strength
• Compatible with R220.21-SC12 cutter series for direct drop-in replacement

Compatibility

Designed for use with the SECO R220.21-SC12 cutter series. The ANSI and ISO code SCET120630T-M14 with insert size code 120630 and series designation SCET-12 defines the physical interface. Verify toolholder pocket geometry before installation.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician with the machine spindle fully stopped and all energy sources locked out per OSHA lockout/tagout procedures. Use the correct torx or hex key to seat the clamping screw to the toolholder manufacturer's specified procedure — do not overtighten. Inspect the insert pocket seat for debris or damage before seating the insert. Replace all four cutting edges before reordering to maximize insert utilization.
