Abstract: A tool guard attachment for a rotary hand tool of the type which has a housing with a nose portion from which an output shaft protrudes and which typically has a mechanism for holding tool bits or implements is disclosed. The tool guard attachment, which mounts to the nose portion of the rotary hand tool, has a guard housing with an enlarged guard portion at the outer end thereof which provides a shield or guard for a flat circular tool implement that is mounted on an arbor shaft assembly that in turn is connected by a U-joint to a drive shaft assembly at an acute angle relative to the arbor shaft assembly. The drive shaft assembly engages a driver nut or the like that is mounted to the output shaft of the rotary hand tool. The angle between the drive shaft and the arbor shaft is offset about 10 to 30° so that the rotary hand tool itself does not interfere with the cutting blade engaging a work surface at a perpendicular angle during operation.
