New Items Marathon Micromotors Posted on September 7, 2017September 7, 2017 by pj_admin We have two new micromotors from Marathon, the N7 and the K-35 Cube. N7 micromotor: 40,000 RPM, strong torque at low speeds, 3/32″ collect, foot control, forward and reverse direction. K-35 Cube: 35,000 RPM, strong torque at low speeds, 3/32″ collect, fixed foot pedal, economical. The micromotor advantage is that it keeps up its torque at slow speeds and it can be set to run at a particular speed and switched on and off by a footpedal. At full speed you cannot feel it running while holding it in your hand. Marathon Micromotors N7 Marathon Micromotor K-35 Cube pj_admin Don’t Let Borax Steal Your Gold! MB Formula.
