Usable for extended periods when grinding， polishing， cleaning， cutting and engraving. Ideal for mechanics， model builders， jewelers， opticians， artists and electronic enthusiasts. This high-revving motor has full-wave electronic speed control capable of producing variable speeds between 5，000 and 20，000 rpm and is usable for extended periods at a time producing an exceptional power/weight ratio. The streamlined die-cast aluminum head provides a stable housing for the ground steel spindle. It runs in a ball bearing assembly， minimizing play (max. runout 0.001). The tool comes with six high concentricity collets sized 1/32 in.， 1/16 in.， 5/64 in.， 3/32 in.， 7/64 in. and 1/8 in. (1.0， 1.5， 2.0， 2.4， 3 and 3.2 mm) along with a collet nut as well as a selection of 34 industrial quality bits and cutters with shanks 3/32 in. (2.3 mm).
