Seco has introduced its new 335.18 disc milling cutter, a robust slotting solution developed for demanding production environments. Available in more than 70 standard variants and fully configurable through the company’s MyDesign platform, the cutter is intended to provide stable, cost‑efficient performance across a wide range of machines, materials, and industry sectors.
Engineered for real‑world challenges, the 335.18 is suited to applications in automotive, aerospace, and general engineering, particularly where long overhangs or less rigid set‑ups — including robotic machining — place higher demands on tool stability. The smooth‑cutting design reduces vibration, extending tool life and supporting consistent accuracy in deep or difficult slotting operations.
The system offers one of the broadest ranges in its class. Users can select from numerous LNKT insert types, corner radii options, integrated wiper flats for improved surface finish, and a full choice of grades and geometries tailored to different materials and cutting conditions. For applications not served by the standard catalogue, Seco’s MyDesign service allows manufacturers to configure a customised cutter body in minutes, providing rapid quoting without extended lead times.
Cost efficiency is a central feature of the new cutter. Its double‑sided inserts offer four usable cutting edges, while the combination of high‑performance grades and a durable Swedish steel cutter body reduces tool changes and overall consumption. Seco says this contributes to more sustainable machining practices while maximising value from each tool investment.
