335.18 cutter body from Seco

The 335.18 and 335.19 cutter bodies from Seco are designed to address the difficulties of disc milling in hard-to-machine materials. Close-pitch insert pockets improve stability and productivity while a plug-and-play internal coolant system improves tool life and chip control. These features, along with a corrosion-resistant body and indexable inserts with four cutting edges, make the tools suitable for machining tough materials like stainless steel, titanium and superalloys.

Designed for slotting operations between 4 and 12 mm and cut-off operations from 4 to 8 mm, the 335.18 and 335.19 cutters are available in metric diameters ranging from 32 to 125 mm. Inch diameters range from 1.25" to 4" with widths from 0.156" to 0.50". Inserts are available with a full range of grades, edge geometries and corner radii (0.2 to 6.0 mm/0.008" to 0.236"). The 335.18 and 335.19 cutters use modular Combimaster connections.


  • Successful Application Of Ceramic Inserts

    Applying ceramic inserts is not a simple substitution of one cutting tool material for another. There are significant process considerations that shops should examine carefully in order to realize performance and tool life expectations from ceramic inserts. Here's a look at some of the ways they are used.

  • Drill And Bore With A Face Mill

    Cutting holes by interpolating a face milling cutter may be a better process choice for many rough and even finish boring operations. Software improvements and better cutter designs allow expanding use of the versatile face mill for hole making.

  • Where Dry Milling Makes Sense

    Liquid coolant offers advantages unrelated to temperature. Forced air is the fluid of choice in this shop...but even so, conventional coolant can't be eliminated entirely.
