  • Publication number: 20250041984
    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.

  • Publication number: 20240408731
    Abstract: A powered fastener driver including a housing, a cylinder, a piston movable within the cylinder from a TDC position to a BDC position, a driver blade 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 operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position, a drive unit operably coupled to the lifter, and a printed circuit board (PCB) positioned within the housing. The PCB receives electrical current from the battery pack and includes power switches for commutating the motor. The PCB defines a length and a width, and a vibration attenuating damper is positioned between the housing and the printed circuit board. The damper is positioned along the length of the PCB and is configured to support the PCB within the housing.

  • Publication number: 20240173822
    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.

  • Publication number: 20230390906
    Abstract: A powered fastener driver including a housing defining a cylinder support portion, a drive unit support portion, and a handle portion that is spaced apart from the drive unit support portion. The powered fastener driver includes a cylinder, a piston movable within the cylinder from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position, a driver blade attached to the piston for movement therewith along a driving axis from the TDC position toward the BDC position, a lifter operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position, and a drive unit supported by the drive unit support portion and operably coupled to the lifter. The powered fastener driver further includes a user interface supported by the housing, and a printed circuit board positioned within the housing and positioned between the drive unit support portion and the handle portion.

  • Publication number: 20230278177
    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.
