A circle cutting accessory for use with a generally cylindrical powered rotary hand tool with an output shaft at one end thereof, the tool having a second accessory attached to the one end, with the second accessory having at its distal end an outwardly extending flange with a first predetermined diameter around a substantial portion of the circumference thereof, the circle cutting accessory including a generally flat housing for receiving and supporting the second accessory and the rotary hand tool. The housing has an upper support surface with an aperture through which a cutting tool attached to the output shaft can pass. The circle cutting accessory further includes a generally horizontal elongated arm mounted to the housing and extends outwardly from the housing. A circle center and sizing elongated member is slidably attached to the arm and has a centering pin extending downwardly therefrom at one end portion. A locking assembly is mounted on the housing and adapted to releasably retain the second accessory and the rotary hand tool.

The quick-release chuck for a rotary power tool is provided for holding a tool bit. The chuck includes a barrel having an axial bore to receive the tool bit and an axially movable sleeve operable to position a locking member to selectively lock or release the tool bit. A proximal end of the chuck near the housing of the power tool includes a low-profile collar which holds a spring in compression against the sleeve, biasing the sleeve in a distal, locked position. The components of the chuck may advantageously be assembled in a stacked manner. The low-profile collar permits the chuck to occupy a minimal length and to be positioned with a minimal separation from the housing of the power tool for enhanced safety.
