The MICROMOT 230/E is designed for drilling, milling, grinding, polishing, brushing, cutting and engraving. The extremely slim housing of glass-fibre reinforced POLYAMIDE with a soft component grip area enables the unit to be handled with two fingers (pen grip). The maximum speed of 21,500rpm can be continuously reduced to 6,500rpm through full-wave electronics. This tool offers nearly the same torque in the lower speed range. This is especially important for micro-drilling, brushing and polishing. Ground, ball-bearing spindle. High quality MICROMOT steel collets.
