Abstract
A tool for use in a well bore has a housing attachable to a work string or drill string wherein the housing supports a floating component that is free to move in the lateral or radial members relative to the housing within predetermined limits. The floating component is suitable for supporting active tool components such as wire bristles, scraper blades or other functional apparatus. Typically, the floating component is provided as a sleeve around the housing held within axial limits, while enabling radial movement.
