Abstract: An orbital sander includes a housing, a motor within the housing and having a drive shaft defining a motor axis, an eccentric drive unit coupled to the drive shaft and configured to convert rotation of the drive shaft to an orbit motion around the motor axis, a sanding pad defining a horizontal work plane and coupled to the eccentric drive unit for orbital motion about the motor axis, and a battery receptacle extending along the housing. The battery receptacle is operable to receive a removable battery pack for providing electrical current to the motor. The battery receptacle defines a battery axis along which the battery pack is installed and the battery axis forms an acute battery angle relative to the work plane.

Abstract: A powered fastener driver includes a housing defining cylinder support portion, a drive unit support portion, and a handle portion that is spaced apart from the drive unit support portion. The handle portion defines a handle axis. A piston is movable within a cylinder from a TDC position to a driven or BDC position. A driver blade is attached to the piston for movement therewith along a driving axis from the TDC position toward the BDC position for driving a fastener into a workpiece. A lifter is operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position. A drive unit is supported by the drive unit support portion and operably coupled to the lifter. The drive unit includes a motor having first output shaft that extends along a motor axis. The motor is positioned below the handle. The handle axis and the motor axis intersect the driving axis.

Abstract: A power tool including a housing, a trigger disposed on an outside of the housing, the trigger including a magnet, a motor within the housing, the motor configured to produce a rotational output to a drive mechanism, a Hall effect sensor configured to sense a position of the trigger based on a proximity of the magnet to the Hall effect sensor, and an electronic controller connected to the Hall effect sensor. The electronic controller is configured to determine the position of the trigger based on a signal from the Hall effect sensor and control the drive mechanism based on the position of the trigger.

Abstract: A powered fastener driver comprising a housing, a nosepiece extending from the housing, a workpiece contact bracket at least partially surrounding the nosepiece, wherein the workpiece contact bracket slides on the nosepiece, a driver blade movable within the nosepiece between a ready position and a driven position, and a drive mechanism operatively coupled with the driver blade to drive the driver blade. The nosepiece includes a tail extending outwardly at least partially along a length of the nosepiece and the workpiece contact bracket includes an internal bore having a tail socket extending at least partially along a length of the workpiece contact bracket, wherein the tail of the nosepiece fits into the tail socket of the workpiece contact bracket to form a slip fit elongated dovetail joint between the nosepiece and the workpiece contact bracket.

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.
