Abstract

A reciprocating saw including a housing, a spindle mounted for reciprocation relative to the housing and having a front end adapted to support a saw blade, the spindle being movable through a cutting stroke and a return stroke, a motor for moving the spindle in a reciprocating fashion, and a reciprocating member interconnecting the motor with the spindle. The motor and the spindle define a drive force path from the motor to the spindle and passing through drive force bearing components of the reciprocating saw, and wherein at least part of the reciprocating member is in the drive force path. The reciprocating member is configured to counterbalance the spindle. A pivot body interconnects the spindle with the motor. A shock absorber is operatively positioned between the motor and the front end of the spindle, and is at least partially mounted within the spindle.
