Seco 74030839 Milling Insert Sean F15M Carbide Tialn

Product Description

The SECO 74030839 is a solid carbide milling insert in the SEAN-12 series, designed for indexable milling operations in demanding cutting environments. Manufactured in a square shape with a 90-degree included angle, it features four cutting edges and a neutral rake geometry with a honed cutting edge style. The insert is coated with a PVD-applied TiAlN and TiN dual coating using manufacturer grade F15M, making it well-suited for cutting hard materials and select cast iron and non-ferrous metal applications. With a maximum depth of cut of 0.3465 inches and a corner radius of 0.0394 inches, it balances edge strength with precise cutting geometry.

This insert is intended for use in indexable milling cutters compatible with the R220.13-12 cutter series. It is a single-sided, wedge-clamp-style insert with a chip breaker designation of E12. Typical applications include face milling and shoulder milling of hard workpiece materials in production machining environments. The primary workpiece material classification is H (hard material), with secondary suitability for cast iron (K) and non-ferrous metals (N). This insert is appropriate for use by machinists and tooling professionals working in CNC milling operations.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the milling cutter body is fully secured and the machine spindle is powered down and locked out before seating or indexing inserts. Use the appropriate torx or clamp screws specified for the R220.13-12 cutter body and do not overtighten wedge clamp components. Inspect the insert pocket for debris or damage before seating the insert to ensure proper contact and runout.
