Powdered portable abrasion tool - uses fractional horsepower motor drive supported by guide on base

摘要

The portable apparatus for reducing the dimensions of a workpiece by abrading means comprises in combination: a portable electric drill motor having a tool shaft-receiving chuck; a workpiece abrasive disc etc, connected with a shaft engaged by the chuck; a guide supporting the drill motor and a base to receive and support the guide adjacent one end and a housing surrounding the abrasive disc adjacent the other end. The base has retentive parallel positioning rails extending longitudinally along each lateral edge of a face of the base. The guide is slidable longitudinally of the base whereby the drill motor is adjustably advanceable toward the end of the base to allow the tool to be aligned with the housing or guard.
