ABSTRACT:
A spindle apparatus operative by a fluid powered reaction turbine-type motor and having a handle portion, a head portion and a device for attaching a desired tool thereto. The handle portion includes a channel for directing the flow of a received fluid. The head portion includes the reaction turbine-type motor which is coupled to an outlet of the channel so as to receive the fluid therefrom. The head portion further includes a rotatable shaft which is coupled to the reaction turbine-type motor and to the attaching device. Upon receiving fluid from the handle portion, the reaction turbine-type motor rotates, thereby causing the shaft and the tool to rotate.
