Rotary abrading or polishing tool

摘要

An abrading or polishing tool comprises a housing that contains a pneumatically drive motor mounted therein. A drive assembly is contained at least partially in the housing and is engaged with the motor to be driven by the motor during operation. A head is engaged with the drive assembly and includes a spindle portion, the head and spindle being rotated during operation of the motor. The head is further configured to engage a working pad for abrading or polishing a work surface. A double bearing assembly is contained within the housing and is engaged with a portion of the spindle adjacent the lower end of the spindle to substantially prevent radial play of the spindle during operation of the tool.
