Foredom Micromotor Kit, Rotary - Flex-shaft Alternative
The magic box.
Not sure whether to buy a flex-shaft or a micromotor? Both have advantages. Let your needs as a fabricator guide your decision.
The major difference between a micromotor and flex-shaft is the motor in the handpiece; the micromotor spins at higher RPMs than a flex-shaft. However it does not have the torque strength of a flex-shaft. The micromotor handpiece is attached directly to the magic box with a flexible cord, so it is easier to wield than a flex-shaft, holds 3/32" mandrels and acts like a H.30 Quick Change Handpiece. You can hold the handpiece like a pencil, allowing for polishing and grinding with extreme precision. Unlike cheaper models, the micromotor is quiet, very fast and very portable.
If your work requires deft and precise abrading, polishing or embellishment, the micromotor is an amazing tool. A micromotor’s speed can be set once freeing you the fabricator to work easily on repetitive tasks such as drilling, cleanup work for production casting, and on one-of-a-kind creations.
The K.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 current, which is required for the handpiece.
The H.MH-170 High Speed Rotary Handpiece has a slender, contoured grip for precise and very high speed work and a 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 2.35mm (3/32") collet that is easy to install and change with the 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. An optional On/Off Foot Switch (HP4-927) is also available separately to turn the motor on and off without changing the speed set by the dial. One Year Warranty Compared to flex shafts, micro motors have much less torque. However, the higher speed of the micromotor results in a comparable rate of material removal with a lighter touch.
The simple cord connection between the handpiece motor and the control box is another key advantage. Unlike the "drag" and general restriction in maneuverability you have with a shaft and sheath, micromotors offer much greater freedom of movement.
