Milling Cutters

  • Our carbide cutters come with one to six cutting edges and are in more than 600 variants available. For machining harder materials, the milling cutters are also available with different coatings. In the following categories single tooth cutters to four tooth cutters you will find with our Varius® line a type of milling cutter, which is

  • suitable for a particularly wide range of applications. Additionally, there is an extensive selection of milling cutters with a grinding for very special materials and tasks (e. g. with a face radius or a left-hand twist).

  • Single tooth cutters

  • Milling cutters with one cutting edge are particularly suitable for plastics, acrylic glass, soft aluminum, aluminium composite panels or soft brass alloys.

  • Single tooth cutters

  • Double tooth cutters

  • Triple tooth cutters

  • With their three cutting edges, these cutters are particularly suitable for the processing of tool steel, gray cast iron, cast steel and heart fittings as well as brass.

  • Triple tooth cutters

  • Four tooth cutters

  • These tools are suitable for materials such as high-alloy steel and tempered steel or cast iron which are hard to cut as well as finishing operations.

  • Four tooth cutters

  • Roughing and finishing cutters

  • Composite cutters

  • For highly abrasive materials like GRP or CRP, we offer a whole series of special milling cutters with cross cut, diamond or spiral toothing.

  • Composite cutters

  • Cross-section single tooth cutter

    In which case should a milling cutter has as few teeth as possible?

    A comparison of the cross-sections of different types clearly shows that the single tooth cutter has the greatest open space (= size of the flute). This leads to the lowest risk of plugging. The more cutting edges a milling cutter has, the more the open space is being reduced. The less cutting edges a milling cutter has - and the more tapered they are -, the easier it is to dip into the surface of the workpiece. It is important to note that the chips are removed over the flute effectively, just so the flute does not get clogged.

    For working on materials which are mainly used for sign making like plastics (PVC, acrylic, rigid foam, etc.) and non-ferrous metals (soft aluminium, aluminium composite plates, soft brass alloys, ...), the single tooth cutter is usually better. The cutting edge erosion is less strong here than the risk of plugging.

    In which case should a milling cutter has as many teeth as possible?

    The cutting edge is the wearing part of the milling cutter. The more cutting edges a milling cutter has, the more cutting edges share the wear. So the endurance, the life-time, of the tool will be prolonged. A milling cutter with more cutting edges has a better true running accuracy than with only one cutting edge. The more cutting edges a tool has, the smaller become the chips. This leads to smoother surfaces.

    A double tooth cutter is recommended when you are working on thermosetting plastics or harder sorts of aluminium (short-chipping).

    We recommend multi-tooth cutters for very hard non-ferrous metals (very hard aluminium alloys, brass, ...) and for ferrous material. Usually, they are also well suitable for finishing operations.
