Seco 74016844 Milling Insert APFT160416R-M13 T25M Carbide

Product Description

The SECO 74016844 is a solid carbide milling insert carrying ANSI/ISO designation APFT160416R-M13 and manufactured to the T25M grade with a CVD-applied TiCN coating. The insert is parallelogram-shaped with an 85-degree included angle, a positive rake angle of 15 degrees, and a right-hand cutting orientation. It features two cutting edges, each with a honed edge style and a 0.063-inch corner radius, making it suited for consistent chip formation in demanding milling operations. The insert is held in the cutter body by screw clamping and is designed for single-sided use. Machinists and CNC tool-setup technicians in job shop and production environments are the primary installers.

This insert is engineered for milling applications in steel, stainless steel, superalloys, and titanium. The M13 chip breaker geometry is optimized for medium-grain cutting conditions where controlled chip evacuation and edge stability are priorities. It is compatible with SECO cutter series R217.69-16 and R220.69-16. Typical applications include face milling, shoulder milling, and contour milling passes where a positive-rake parallelogram insert provides reduced cutting forces and extended tool life on difficult-to-machine alloys.

Key Features

• T25M grade solid carbide substrate with CVD TiCN coating for wear resistance on steel and superalloy materials
• M13 chip breaker geometry engineered for medium-grain milling in steel, stainless steel, superalloys, and titanium
• Positive rake angle of 15 degrees reduces cutting forces and heat generation at the edge
• Honed cutting edge style on both edges promotes edge stability and reduces micro-chipping
• Right-hand, single-sided insert with screw holding method for secure, repeatable seating
• 0.063-inch corner radius balances surface finish quality with insert strength

Compatibility

Designed for use with SECO cutter series R217.69-16 and R220.69-16. The insert carries ANSI/ISO code APFT160416R-M13 and is qualified to ISO standards for use in milling applications on steel, stainless steel, superalloys, and titanium workpiece materials (ISO material codes P, M, and S).

Installation Notes

Insert seating and replacement should be performed by a qualified machinist or CNC tooling technician with the spindle fully stopped and the machine in a locked-out, tagged-out state. Use the appropriate Torx or hex key driver to seat the clamping screw to the tool body manufacturer's specified torque — consult the cutter body documentation for that value. Inspect the insert pocket and seating surface for debris or damage before seating a new insert. Minimum order quantity for this insert is 10 pieces; package quantity is 1.
