Seco 02505952 Milling Insert Triangle F40M Solid Carbide

Product Description

The SECO 02505952 is a solid carbide triangular milling insert in the TPUN-16 series, designed for high-performance metal removal in professional machining environments. It carries a dual-layer TiAlN and TiN PVD coating applied over a fine grain carbide substrate in manufacturer grade F40M, providing wear resistance across demanding cutting conditions. The insert features a neutral rake, T-Land cutting edge style, and a 0.0315 inch corner radius. With 3 usable cutting edges and a maximum depth of cut of 0.5315 inches, it is suited for intermittent and continuous milling passes on a variety of workpiece materials. Installation and tool setup is performed by qualified machinists and CNC operators.

This insert is intended for milling applications in metalworking and machining operations where the primary workpiece materials are steel, cast iron, superalloys, and titanium. Secondary workpiece compatibility extends to cast iron and non-ferrous metals. The TPUN160308T ANSI and ISO designation makes it straightforward to cross-reference within standard tooling systems. It is compatible with the R220.17-16 cutter series. The neutral hand orientation and wedge clamp holding method suit a range of milling cutter body configurations in both roughing and semi-finishing passes.

Compatibility

Compatible with the R220.17-16 cutter series. Rated for primary workpiece materials including steel, cast iron, superalloys, and titanium, with secondary compatibility for cast iron and non-ferrous metals. ANSI and ISO designation TPUN160308T allows direct cross-reference to standard tooling catalogs.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Always power down and lock out the machine spindle before seating or replacing inserts. Use the appropriate torque wrench or insert key specified by the cutter body manufacturer when tightening the wedge clamp to avoid insert cracking or seating errors. Inspect the cutter pocket and clamp for wear or debris before installing a new insert.
