Seco 02656105 Milling Insert SEMX1204AFTN-MD19 MP3000

Product Description

The SECO 02656105 is a solid carbide milling insert carrying ANSI and ISO designation SEMX1204AFTN-MD19, manufactured in the MP3000 micrograin carbide grade with a PVD-applied TiAlN coating. The insert is square in shape with a 90-degree included angle, four usable cutting edges, and a neutral rake and hand orientation. Key dimensions include a 0.5 inches inscribed circle, 0.1874 inches thickness, and a 0.0441 inches corner radius. The T-Land cutting edge style and MD19 chip breaker geometry are optimized for controlled chip formation in demanding milling applications. This insert is selected by machinists and tooling specialists working in production and job-shop environments.

This insert is suited for milling steel, stainless steel, and hard materials, covering ISO material groups P, M, and H. It is designed for use in face milling and shoulder milling cutter bodies in the R217.53-12 and R220.53-12 series. The maximum depth of cut reaches 0.3425 inches, making it appropriate for moderate to aggressive material removal passes. The single-sided configuration and screw-holding method are standard for this insert family. Applications span both roughing and finishing operations where TiAlN coating provides thermal and abrasion resistance.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the cutter body is removed from the spindle and the machine is locked out before seating or replacing inserts. Use the correct torx or hex key to seat the clamping screw to the cutter body manufacturer specification — do not use power tools to tighten insert screws. Inspect the insert pocket and screw for damage or debris before installing a new insert.
