This is a Marathon Handy 700 micromotor handpiece set for the dental lab. This unit features a 50,000 rpm brushless electric micromotor handpiece. The benefits to this design are: less noise, smoother operation, and longer life than conventional electric micromotors. The control box is digitally controlled and has outlets for 2 handpieces: the brushless 50,000 rpm handpiece plugs in the back, and a conventional electric micromotor (with a 3 prong design) can be plugged in the front. There is also a handpiece holder on the side as well as a magnetic bur holder. The set includes: control box, 50,000 rpm handpiece, foot pedal, 2 handpiece holders, a variable-speed foot pedal, tools, and manual. Operates on 110 volts. Made in Korea.
