The invention relates to a power tool apparatus which is provided to perform an abrasion work operation on a workpiece, said apparatus including at least one spindle which is driven to rotate and a plurality of abrasion components which can be selectively attached to the spindle, said abrasion components provided in different configurations to perform different work operations and selectable by the user with regard to the particular work operation to be performed on a workpiece at that time. The speed of rotation of the spindle is manually or automatically adjustable so as to allow the speed of rotation of the abrasion component to be optimised with regard to the particular work operation to be performed. In one embodiment, the said speed of rotation is one of a range of predetermined speeds which can be manually selected by the user via user actuation means or may be automatically set upon detection of a particular component being fitted to the spindle at an instant of time of use.
An abrasion power tool apparatus, said apparatus including a housing, a motor which, when provided with a power supply, is operable to rotate at least one spindle located externally of the said housing, one or more abrasion components including an abrasion surface, said one or more abrasion components selectively engageable with the spindle such that, when engaged, the abrasion component is rotated by the spindle to perform a work operation on the surface of a workpiece placed against the same and wherein, the apparatus includes adjustment means to allow the adjustment of the speed of rotation of the spindle to a selected speed within a range of speeds, with the selection being made with respect to the abrasion component fitted to the spindle and/or the work operation to be performed on the workpiece at the instant of time of use.
A method of using an abrasion power tool apparatus, said method including the steps of mounting the apparatus on a support surface, selecting to locate and engage an abrasion component including an abrasion surface on at least one spindle located on said housing, providing a power supply to a motor to operate the same and rotate the said spindle and abrasion component, bringing a workpiece into contact with the moving abrasion surface to perform a work operation on the surface of the workpiece and wherein operating adjustment means to select the speed of rotation of the said spindle prior to and/or during the performance of the said work operation.
