Seco 74017048 Milling Insert APFT160440R-M13 T25M Carbide

Product Description

The SECO 74017048 is a solid carbide milling insert carrying the ANSI and ISO designation APFT160440R-M13. It is engineered for use in indexable milling cutters where consistent edge performance across steel, stainless steel, superalloys, and titanium is required. The insert features a TiCN coating applied via CVD process and is manufactured to the T25M grade, a medium-grain carbide grade suited for moderate-to-demanding milling conditions. With a positive rake angle of 15 degrees and a honed cutting edge style, it delivers controlled chip formation and reduced cutting forces. Machinists and tooling specialists install this insert as part of a planned indexable tooling setup on CNC milling platforms.

This insert is intended for use in production and job-shop milling operations targeting steel (P), stainless steel (M), superalloys, and titanium (S) workpiece materials. It is designed for right-hand cutting applications and fits within the APFT-16 insert series. The M13 chip breaker geometry supports medium-depth milling passes. Compatible cutter series include the R217.69-16 and R220.69-16 milling cutter bodies, as stated by the manufacturer. It is a single-sided insert held in place by a screw-type clamping method.

Key Features

• TiCN coating via CVD process for wear resistance in steel and stainless steel milling
• T25M medium-grain solid carbide grade for balance of toughness and hardness
• Positive rake angle of 15 degrees reduces cutting forces and heat generation
• M13 chip breaker geometry supports controlled chip evacuation during medium-depth cuts
• Honed cutting edge style for improved edge stability and surface finish
• Right-hand orientation with screw holding method for secure, repeatable seating

Compatibility

Compatible with SECO milling cutter bodies in the R217.69-16 and R220.69-16 series, as specified by the manufacturer. This insert uses the APFT-16 series designation and is confirmed for right-hand cutter configurations.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with indexable insert tooling systems. Before indexing or replacing inserts, the machine spindle must be fully stopped and locked out per applicable machine safety procedures. Use the appropriate Torx or hex key as specified by the cutter body manufacturer when seating the clamping screw — do not overtighten, as carbide inserts are brittle and can crack under excess clamping force. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert.
