35 watts of power and a variable operating speed between 8,000 and 18,000 RPM make the MicroLux Mini Rotary tool strong enough for the most challenging projects. A total weight of just 8 oz and the thinnest design available in this power range (3/4 inch at the tip and 1-5/16 inches along the barrel) make for one of the most ergonomic high-powered rotary tools in the world. Includes collet set (1/32 inch, 3/32 inch and 1/8 inch) and wrench. Uses an incredibly wide variety of standard rotary tool bits and accessories. Unlike other similar-size tools, the Mini operates on standard 110V household current; no transformer needed. 50/50 duty cycle. Made in Japan.
