Abstract
An electric powered rotary hacksaw includes a cylindrical housing, an integral longitudinally extending mounting member and a rotary circular hacksaw blade disposed at one end of the mounting member. The hacksaw blade is fixed to a shaft for rotation about an axis which is generally perpendicular to the longitudinal axis of a mounting member. A variable speed electric motor is disposed in the housing and includes a shaft which extends forwardly in a direction parallel with the longitudinal member. A frustoconical driver member of an elastomeric material is fixed to the end of the shaft and engages the circular blade to displace a portion of the blade out of its normal plane of rotation by an angle of about 5 degrees and for rotating a circular blade.
