Seco 74018710 APKT1604PDR-E12 T25M Milling Insert

Product Description

The SECO 74018710 is a solid carbide milling insert carrying ANSI and ISO designation APKT1604PDR-E12 in manufacturer grade T25M. The insert features a parallelogram shape with an 85-degree included angle, a positive rake of 22 degrees, and a 11-degree relief angle. A TiCN coating applied via CVD process gives the cutting edges enhanced wear resistance and thermal stability. At 0.187 inches thick and 0.375 inches wide, this single-sided, right-hand insert delivers two honed cutting edges with an effective length of 0.6476 inches and a maximum depth of cut of 0.6220 inches. It is screw-mounted and suited for demanding milling applications across ferrous and exotic workpiece materials.

This insert is designed for machining steel, stainless steel, superalloys, and titanium, covering material codes P, M, and S. The E12 chip breaker geometry manages chip control across a range of feed rates typical in face milling and shoulder milling operations. It is compatible with SECO cutter series R217.69-16 and R220.69-16. The T25M grade and CVD TiCN coating make this insert well suited for medium-grain, medium-to-high cutting speed applications where tool life and edge stability are priorities. Machinists and CNC operators working in job shop or production environments will find this insert appropriate for both roughing and semi-finishing passes on the stated workpiece materials.

Key Features

• TiCN CVD coating for improved wear resistance on steel, stainless steel, superalloys, and titanium
• Positive rake angle of 22 degrees reduces cutting forces and improves chip flow
• Honed cutting edge style promotes edge stability and reduces micro-chipping
• E12 chip breaker geometry for effective chip control across varied feed rates
• Two cutting edges per insert maximize tool economy on a single-sided body
• Screw-mount holding method provides secure, repeatable seating in compatible cutter bodies

Compatibility

Compatible with SECO cutter series R217.69-16 and R220.69-16. Insert size code 1604, ANSI and ISO designation APKT1604PDR-E12, series APKT-16.

Installation Notes

Installation is performed by a qualified machinist or CNC tooling technician. Power down and lock out the spindle before seating or replacing inserts. Use the correct torx or hex key to the cutter body manufacturer's specified procedure when tightening the mounting screw, and confirm the insert seats flush with no rocking. Inspect the pocket for chips or debris before each insert change to prevent premature edge failure or pocket damage.
