A belt sander for sanding a workpiece and defining a center of gravity within a first plane. The belt sander includes a housing, a handle defining a second plane, and a drive unit disposed within the housing. The drive unit includes a motor disposed adjacent a first sidewall of the housing, a pulley system disposed adjacent a second sidewall of the housing opposite the first sidewall, and a transmission disposed between the motor and the pulley system. The belt sander further includes a belt drive system driven by the drive unit and including a drive wheel, a driven wheel, and a platen. The platen defines a third plane extending perpendicular therefrom. The transmission and pulley system are disposed on one side of the first plane and the motor is disposed on an opposite side of the first plane. The motor is intersected by the second and third planes.

An oscillating power tool includes a housing, a motor disposed generally within the housing and including a drive shaft, an output spindle configured to be driven by the motor and journaled for oscillating rotation about an oscillation axis, a drive mechanism configured to convert rotation of the drive shaft into oscillating rotation of the output spindle about the oscillation axis, the drive mechanism including an eccentric member configured to rotate off center about the motor axis, and a forked member operatively coupled to the eccentric member and configured for oscillating rotation about the oscillation axis in response to rotation of the eccentric member, and an amplitude adjustment actuator configured to move the eccentric member in the direction generally parallel to the motor axis to change an angular amplitude of oscillating rotation of the forked member.

Oscillating power tool with adjustable angular amplitude of oscillation

An oscillating power tool includes an outer housing, and an inner housing positioned within the outer housing. A motor and a drive mechanism are supported by the inner housing. The drive mechanism includes an output shaft that is rotational in an oscillating manner and that defines an output axis. A damping element is positioned between the inner housing and the outer housing through which the inner housing is mounted to the outer housing, thereby attenuating vibration transmitted to the outer housing from the inner housing. An over-travel limit member is positioned between the inner housing and the outer housing. In response to relative movement between the inner housing and the outer housing while the power tool is in use, the limit member is configured to prevent direct contact between the inner housing and the outer housing, inhibiting vibration produced by the motor and/or drive mechanism from bypassing the damping element.

Oscillating power tool

An oscillating power tool has a housing including a handle portion defining a handle axis and a head portion defining an output axis that is perpendicular to the handle axis. The head portion includes a front face intersected by the handle axis. A drive mechanism includes an output shaft configured to oscillate about the output axis in a rotational manner in response receiving torque from a motor. A lighting assembly is configured to illuminate a workpiece in front of the head portion of the housing. The lighting assembly includes a lens arranged on the front face of the housing, a holder coupled to the lens, a plurality of printed circuit boards supported by the holder, and an LED arranged on each of the printed circuit boards. In response to being activated, the LEDs are configured to project a wide-angle beam of light through the lens.

Oscillating power tool with lighting assembly

A handheld band saw includes a housing, a handle coupled to the housing and configured to be grasped by a user during a cutting operation, a motor supported by the housing, and a drive wheel assembly rotationally driven by the motor. The drive wheel assembly at least partially disposed within the housing. The band saw further includes a saw blade driven by the drive wheel assembly. The saw blade is configured to cut a workpiece during the cutting operation. The band saw further includes a pipe reamer attachment coupled to the drive wheel assembly. The pipe reamer attachment is configured to deburr the workpiece after completion of the cutting operation.

Band saw

An oscillating power tool including a housing, a motor including a drive shaft rotatable about a motor axis, an output spindle configured to be driven by the motor and journaled for oscillating rotation about an oscillation axis, and a drive mechanism. The drive mechanism is configured to convert rotation of the drive shaft into oscillating rotation of the output spindle about the oscillation axis and includes an eccentric member and a forked member. Oscillating rotation of the forked member has an angular amplitude about the oscillation axis. The eccentric member is movable with respect to the forked member to change the angular amplitude of oscillating rotation of the forked member. An amplitude adjustment actuator is configured to move the eccentric member to change the angular amplitude of oscillating rotation of the forked member. The amplitude adjustment actuator defines a receptacle. At least a portion of the forked member is disposed in the receptacle.
