Four tooth cutters
The four-toothed Varius® is ideal for very hard materials, e. g. for tempered steel, cast and other sorts of material which are difficult to machine. By standard available with STRATUM TN coating.
Some diameters are available with STRATUM HL coating, which is especially suitable for roughing thanks to its excellent hardness.
Milling cutter with different lead angles of its four flutes. This asymmetry facilitates a vibration-free running and counteracts the “cork-screw effect”.
