Seco 74017003 APKT1604PDTR-M14 T25M Milling Insert

Product Description

The SECO 74017003 is a solid carbide milling insert carrying ANSI and ISO designation APKT1604PDTR-M14. It features a parallelogram shape with an 85-degree included angle, a positive rake geometry at 22 degrees, and a T-Land cutting edge style. The insert is CVD-coated with TiCN in manufacturer grade T25M, a medium grain carbide substrate suited for demanding milling operations. With 2 cutting edges and a right-hand orientation, it is designed for use in indexable milling cutters. Licensed machinists and tooling technicians install this insert in production and job-shop environments where consistent edge geometry and coating durability are required across steel, stainless steel, and superalloy workpieces.

This insert is intended for milling applications involving steel, stainless steel, superalloys, and titanium, covering material codes P, M, and S. It is suited to both roughing and semi-finishing passes where the M14 chip breaker geometry manages chip flow effectively. The insert seats via a screw-holding method in compatible indexable milling cutter bodies. It is a single-sided insert, and its positive rake angle reduces cutting forces, making it appropriate for setups where rigidity or machine power is limited.

Key Features

• CVD TiCN coating in T25M grade for wear resistance in steel and stainless steel milling
• M14 chip breaker geometry for effective chip control in medium-grain carbide
• Positive rake angle (22 degrees) reduces cutting forces and thermal load
• T-Land cutting edge style improves edge strength and chipping resistance
• 2 cutting edges per insert, right-hand orientation, screw-clamped mounting
• Parallelogram shape with 11-degree relief angle for clearance during cut

Compatibility

Compatible with SECO cutter series R217.69-16 and R220.69-16. This insert uses ANSI and ISO code APKT1604PDTR-M14 and belongs to the APKT-16 insert series.

Installation Notes

Installation is performed by qualified machinists or tooling technicians familiar with indexable insert tooling. Before seating the insert, clean the pocket and screw threads to remove chips and debris that could affect insert seating and runout. Torque the clamping screw using the tool manufacturer-specified wrench; do not use impact tools. Inspect the cutting edge condition at regular intervals and index or replace the insert before edge failure causes surface finish or dimensional issues.
