Abstract: A jigsaw including a housing, a handle extending transverse from the housing in a direction of a handle axis, a battery selectively coupled to the handle, a foot plate coupled to the housing and configured to contact a workpiece, and a drive assembly powered by the battery. The drive assembly includes a motor, a fan, a transmission driven by the motor, and an output spindle driven by the transmission and coupled to a cutting blade. The jigsaw also includes a frame supported within the housing which supports the motor and the transmission. The frame includes a shroud surrounding at least a portion of the fan and an air chute in fluid communication with the shroud that together direct an airflow produced by the fan toward a cutting area adjacent the cutting blade. The jigsaw also includes a baffle that is selectively moveable into the air chute to redirect the airflow away from the cutting blade.

Abstract: A random orbit sander includes a housing and a motor enclosed within the housing. The motor includes a motor shaft that is rotatable about a first axis. An eccentric carrier coupled to the motor shaft includes a circular internal bore that defines a second axis that is offset from the motor shaft. A bearing is received within the circular internal bore of the eccentric carrier. A sanding pad is supported by the bearing and is rotatable about the first axis in an eccentrically orbiting manner. The motor shaft and the eccentric carrier are integrally formed as a single piece.
