Seco 02566063 Milling Insert SEEX1203AFTN-MD14 MK1500

Product Description

The SECO 02566063 is a solid carbide milling insert carrying ANSI and ISO designation SEEX1203AFTN-MD14 in manufacturer grade MK1500. It features a square shape with a 90-degree included angle, four cutting edges, and a neutral rake and hand orientation. The CVD-applied Duratomic coating combines TiCN and Al2O3 layers for elevated wear resistance in demanding cutting applications. With a maximum depth of cut of 0.0866 inches and a T-Land cutting edge style, this insert is engineered for controlled, repeatable performance in face and shoulder milling operations. Machinists and toolroom technicians install this insert using a wedge clamp holding method.

This insert is designed primarily for milling cast iron workpieces, designated by material code K. The MD14 chip breaker geometry promotes effective chip evacuation at the cutting zone, reducing heat buildup and extending edge life on gray and ductile cast iron. Typical install scenarios include face milling, shoulder milling, and light profiling operations on CNC machining centers in production and job-shop environments. The insert is compatible with SECO cutter series R217.53-12 and R220.53-12 as stated by the manufacturer.

Key Features

• Square SEEX insert style with 90-degree included angle and four usable cutting edges
• CVD Duratomic coating with TiCN and Al2O3 layers for wear and crater resistance
• T-Land cutting edge style for controlled entry and reduced chipping on cast iron
• MD14 chip breaker geometry optimized for cast iron chip control
• Neutral rake and neutral hand for flexible cutter body orientation
• Wedge clamp insert holding method for secure seating under milling loads

Compatibility

Confirmed compatible with SECO cutter series R217.53-12 and R220.53-12. This is a single-sided insert in the SEEX-12 series and is designed as an OEM-specification replacement for applications requiring ANSI/ISO code SEEX1203AFTN-MD14.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians familiar with indexable insert tooling. Power down and lock out the machine spindle before seating or indexing any insert. Ensure the insert pocket and wedge clamp are free of chips and debris before securing the insert. Do not overtighten the clamp screw; follow the cutter body manufacturer torque specifications for the specific cutter body in use.
