Seco® releases the 335.18 disc milling cutter, a robust and customizable slotting solution engineered for real-world manufacturing. With over 70 standard variants and full customization via MyDesign, the 335.18 delivers stable, cost-efficient performance for any industry, machine, or material enabling manufacturers to achieve precision and reliability in every slotting operation.
Slotting solutions for the real world
The 335.18 disc milling cutter is designed to tackle the toughest slotting challenges across automotive, aerospace, and general engineering sectors. Its smooth-cutting design ensures fewer vibrations, longer tool life, and reliable results. It is particularly suitable for long overhangs or even in weaker setups, such as robotic arms.
Design your own indexable slotting cutter
With one of the broadest ranges on the market, the 335.18 system features a wide selection of LNKT inserts, various corner radii, integrated wiper flats for fine finishes, and a complete portfolio of grades and geometries. If the standard range doesn’t fit, MyDesign allows users to configure and quote a custom cutter body in minutes—no waiting, no guesswork.
Cost efficiency is at the core of the 335.18’s design. Double-sided inserts with four cutting edges, high performance grades, and a durable Swedish steel cutter body deliver extended tool life and fewer replacements, supporting sustainable manufacturing and maximizing value for every investment.
