ABSTRACT:
A circular cutter 10 has a drive shaft 11 that turns a beam 30 bearing one or two cutter knives 50 rotated within a drum 20 mounted on shaft 11 to surround beam 30. A pressure shoe 25 on the bottom of drum 20 has a central opening 26 within which cutter knives 50 can turn, and drum 20 is biased downward relative to shaft 11 and beam 30 so that pressure shoe 25 engages and holds a work piece 60 as it is cut. Pressure shoe 25 is preferably interchangeable to afford different sizes of central openings 26 for different radii of cuts, knives 50 are preferably radially adjustable along beam 30, and drum 20 is preferably transparent to serve as a guard that the user can see through.
