Compared to flex shafts, micro motors have much less torque, however, the higher speed results in a comparable rate of material removal with a lighter touch. The simple cord connection between the handpiece motor and control box is another key advantage. Unlike the "drag" and general restriction in maneuverability you have with a shaft and sheath, micro motors offer much greater freedom of movement.

The NEW 1070 Kit includes:

The HP4-917 Control Box is compact with switches on the front for On/Off Power, Forward or Reverse Rotation, and Manual or Foot Speed Control. Speed can be adjusted from low to full speed using the dial on the box or with the foot pedal. An Overload Protector Light is also featured that turns red and sounds a beeping alarm when the motor stalls.

The back of the control box has a convenient voltage selector switch for operating with either 115 volt or 230 volt. The control converts AC current to DC cuurrent required for the handpiece.

The MH-170 High Speed Rotary Handpiece has a slender, contoured grip for precise and very high speed work and quick release rotary type chuck. It has a fan cooled, brush-type continuous duty motor that runs cool and vibration free with permanently lubricated, shielded ball bearings that require no lubrication. It comes with a 3/32" (2.35mm) collet that is easy to install and change with supplied collet changing wrench. Optional 1/8" and 3mm collets are available separately. Bur changes are quick and easy with a simple twist of the front section of the Handpiece. A cradle is also supplied for the handpiece when not in use. A selection of collet adapters is available for simplifying changes between accessories with different shank sizes.

Handpiece specifications: 6.2" overall length, 5/8" grip diameter, 1" motor diameter, 7.3 oz./208 gr., DC30V/1.2A. CE marked.
