Seco 74017050 Milling Insert APFT160448R-M13 T25M Carbide

Product Description

The SECO 74017050 is a solid carbide milling insert carrying the ANSI designation APFT160448R-M13 and manufacturer grade T25M. Designed for indexable milling operations, this right-hand parallelogram insert features a CVD-applied TiCN coating over a medium-grain carbide substrate. The M13 chip breaker geometry and positive 15-degree rake angle work together to control chip flow and reduce cutting forces during interrupted and continuous milling passes. With two cutting edges per insert and a honed cutting edge style, it delivers consistent performance across steel, stainless steel, superalloys, and titanium workpieces. A licensed machinist or toolroom technician installs it using a screw-holding method into compatible SECO cutter bodies.

This insert is suited for face milling and shoulder milling applications in both production and job-shop environments. Primary material applications include steel, stainless steel, superalloys, and titanium, covering ISO material groups P, M, and S. The M13 chip breaker is optimized for medium-grain cutting conditions typical in general machining and finishing passes. Compatible cutter series include the SECO R217.69-16 and R220.69-16 milling bodies. The insert seats securely via a center screw and is designated for right-hand cutter orientation. Minimum order quantity is 10 inserts; package quantity is 1.

Key Features

• Solid carbide construction with medium-grain substrate for toughness and wear resistance
• CVD TiCN coating improves heat and abrasion resistance during steel and stainless milling
• M13 chip breaker geometry supports controlled chip flow in medium cutting conditions
• Positive 15-degree rake angle reduces cutting forces on the workpiece and spindle
• Two usable cutting edges per insert extend tool life before disposal
• Honed cutting edge style minimizes micro-chipping on entry and exit

Compatibility

Designed for use with SECO cutter series R217.69-16 and R220.69-16 milling bodies. Compatible with steel, stainless steel, superalloy, and titanium workpiece materials (ISO groups P, M, and S). Insert conforms to ANSI and ISO code APFT160448R-M13.

Installation Notes

Installation is performed by a machinist or toolroom technician following the cutter body manufacturer torque specifications for the center clamping screw. Ensure the spindle is fully stopped and the machine is locked out before indexing or replacing inserts. Inspect the pocket seat and screw threads for debris or damage before seating a new insert. Follow ISO indexable insert handling guidelines and cutter body documentation for proper torque sequence.
