For high speed applications up to 38,000 rpm including light deburring of cast pieces, bright cutting in jewelry making and fine detailing in wood. Kit includes control box, handpiece with 2.35mm (3/32″) or 1/8″ collet (depending on choice of collet installed), variable speed foot control, handpiece cradle, spare pair of motor brushes, spare fuse and collet changing wrenches. The back of the control box has a convenient Voltage Selector switch for operating with either 115 or 230 Volt operation. This Kit is already set for 110-115 Volt use. The control converts AC current to DC current required for the handpiece. Compared to flexible shaft machines, micromotors have less torque, however, their 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 movement that you have with a shaft and sheath, micromotors offer much greater freedom of movement.
