Abstract:

According to the present invention, a rotary trim saw includes a rotary drive shaft coupled to a source of rotary power, while a sleeve is disposed about the drive shaft. The drive shaft is arranged for rotation relative to the sleeve. Also, a rack is disposed on an outer surface of the sleeve and parallel to the drive shaft, and a circular cutting blade is disposed at an end of the drive shaft. A base is attached and has a pinion for engaging the rack and an adjustment knob coupled to the pinion for controlling the position of the blade relative to the base. The rotary trim saw may also have a base having surface engaging wheels attached to the base such as ball bearings although other types of wheels would also suffice such as coaster wheels. The base may also include a set screw for locking the base to the sleeve, so as to lock the cutting blade relative to the base or may also include a level attached to aid in determining a cutting angle. Retractable safety shields may also be attached to the base.
