Marathon Micromotor System

Total ---
The affordable do-it-all rotary micromotor system! Great for polishing and texturing jewelry surfaces, sizing, drilling, stone setting, making beautiful bright-cuts and much more. Helps increase production, saving you time and money. Allows quick tool changes to keep work flowing. Provides finer control and better range of motion than a traditional flex shaft to handle especially delicate jobs. 

Includes compact 110/220V controller with dial speed control and forward/reverse direction switch, 35,000rpm lightweight rotary handpiece with quick-change collet and flexible curl cord, variable-speed foot rheostat TPF-77, handpiece cradle rest and safety glasses. Controller also accommodates our full line of Power Hand 2X Handpieces.

Marathon is available with your choice of collet size: 3/32", 1/8" and 3.0mm (Collets are interchangeable.) For diamond "bright cutting", choose the Marathon System with 3mm collet and any of our Diamond Flywheels (see "Related Products" below). Made in South Korea.
