With a maximum speed of 35,000 rpms, the Marathon K-3 Micromotor gets you started power carving with a low initial investment. The light, comfortable handpiece connects to the power supply/speed control unit with an extremely flexible 6′-long self-coiling cord. Equipped with a 1/8″-diameter collet, you can change most common bits with a twist of your wrist. To use bits with a 3/32″-diameter shaft, slip in the reducing sleeve and insert the bit as normal.
Instead of fighting a cumbersome flexible shaft, or scorching your hands using an inexpensive rotary tool, carve, grind, cut, shape, sand, and de-fuzz in complete comfort. The unit features 3.2Ncm of torque and one of the quietest motors on the market.
