Abstract: There is provided a surface abrasion apparatus featuring overlapping abrasion paths to prevent tooling marks; a spaced housing, aluminum monocoque motor design and vacuum venturi to prevent overheating of the apparatus during operation; positioning of the tool plates to allow abrasion adjacent a vertical wall; O-ring seals to allow operation in wet conditions; magnetic and hook and fastener attachment of tool segments to allow ease of tooling; and articulation of the handle to permit greater operability.

Abstract: Thus, according to one aspect, the invention provides a system for mounting an abrasive tool to a drive plate of a polisher or grinding tool, the system comprising: an intermediate element mounted to a surface of the drive plate via a first securing means; and a second securing means for securing the abrasive tool to the intermediate element. The intermediate element may be a tool mounting plate and the second securing means is at least one pin and spring assembly. The intermediate element may be a ring and the second securing element comprises magnets and pins. The intermediate element may be a circular bracket and the second securing element comprises rotary slot attachment.
