ABSTRACT:
An elongate, cylindrical hand-held powered coping saw adapted for making thin cuts of short length, such as for cutting individual dies from a full arch dental model generally includes a blade assembly, a housing, a rotary motor having a drive shaft, a piston for driving the blade assembly, and a motion converter connecting the drive shaft to the piston for converting rotary motion of the drive shaft into reciprocating linear motion of the piston. Preferably, the blade stroke length is less than the distance between opposing U-sections of a full dental arch model along a cut line.
