Disc Milling

The cornerstone of Seco's approach to disc milling is to offer the widest range of inserts, cutter bodies, and attachment types in the industry.

When it comes to disc milling, we’ve long offered the widest selection of inserts, cutter bodies and attachment types in the industry — and our new 335.14 and 335.16 product lines further prove it. We also go out of our way to expand our existing disc milling cutters, most recently our 335.25 line, to keep pace with the natural progression of the marketplace.

Whether you perform grooving, sawing, T-slotting, copy milling, back facing or helical interpolation, you’ll find our complete selection of disc mill cutters, which now spans eight product lines, has what it takes to bring increased productivity and profitability to your parts, regardless of the industry segments you serve.
