Selected wolfram vanadium steel. Purpose-made stable construction with head and shaft out of a single blank. The precise flutes and optimal concentricity ensure best life expectancy. Ideal for freehand precision work. For use on hard and soft woods, non-ferrous and precious metals, as well as plastics and plaster of Paris. All shafts Ø 2.35 or 3.0mm. Ideal for milling, routing, shaping, profiling and slotting. For clean and powerful fitting of the milling bits we recommend the use of MICROMOT steel collets.
