Seco 74017234 Milling Insert ACET150612TR-M14 T25M Carbide

Product Description

The SECO 74017234 is a solid carbide milling insert carrying ANSI and ISO designation ACET150612TR-M14, manufactured in the T25M medium-grain carbide grade with a CVD-applied TiCN coating. It is a single-sided, right-hand parallelogram insert in the ACET-15 series, featuring a positive rake angle of 15 degrees, a T-Land cutting edge style, and two cutting edges per insert. With a 7-degree relief angle and a corner radius of 3/64 inch (0.0472 inches), this insert is engineered for milling applications in steel, stainless steel, superalloys, and titanium. It is installed by machinists and tooling technicians using a screw-holding method in compatible cutter bodies.

This insert is designed for use in face milling, shoulder milling, and general milling operations on steel, stainless steel, superalloys, and titanium workpieces. The T25M grade with TiCN CVD coating provides wear resistance and thermal stability suited to medium-grain cutting demands in these material categories. The M14 chip breaker geometry supports controlled chip formation across a range of cutting conditions. Compatible cutter series include R220.69-15H, R217.59-12, R220.59-12, R217.81, and R220.81, as specified by the manufacturer. This insert is sold individually with a minimum order quantity of 10 units.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Power down and lock out the machine spindle before removing or seating any insert. Seat the insert fully against the pocket faces before torquing the clamping screw; do not force an insert that does not seat cleanly, as this indicates a worn or contaminated pocket. Inspect the cutter body pocket and screw threads for damage each time inserts are changed.
