Seco 00004903 SCET120612T-M14 F40M Carbide Milling Insert

Product Description

The SECO 00004903 is a solid carbide milling insert carrying ANSI and ISO designation SCET120612T-M14 and manufactured to grade F40M with a fine-grain carbide substrate. The insert features a square shape with a 90-degree included angle, four cutting edges, and a neutral hand orientation. A PVD-applied TiAlN plus TiN dual coating provides wear and oxidation resistance during high-speed milling operations. The cutting geometry includes a 15-degree rake angle with a T-Land cutting edge style and a 7-degree relief angle, optimizing chip formation across a range of workpiece materials. Machining professionals and CNC mill operators working in job shops or production environments will find this insert suited to demanding face and shoulder milling applications.

This insert is designed for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium. Primary material codes are P, K, and S, with secondary codes K and N also supported. The M14 chip breaker geometry manages chip evacuation effectively across these material groups. Compatible cutter series include R217.59-12 and R220.59-12, making this insert appropriate for shoulder milling heads in those series. The maximum depth of cut reaches 0.4528 inches, and the 0.5-inch inscribed circle diameter suits mid-size cutter bodies. The insert is screw-held and single-sided.

Compatibility

Designed for use in SECO cutter series R217.59-12 and R220.59-12. Conforms to ANSI and ISO code SCET120612T-M14. Verify pocket geometry and screw size against cutter body documentation before installation.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before seating or indexing inserts. Clean the insert pocket and confirm the seating surface is free of chips or debris before torquing the clamping screw. Follow the cutter body manufacturer's specified screw torque procedure as outlined in the toolholder documentation.
