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.

A drain cleaner includes a shroud with a closed end and an open end opposite the closed end and a drum assembly positioned within the shroud. The drum assembly is rotatable relative to the shroud. The drum assembly includes an inner drum and a drum cover extending entirely over an open forward end of the inner drum. The drain cleaner also includes a flexible cable stored within a cavity defined by the inner drum and the drum cover of the drum assembly. The flexible cable is supported by the inner drum. The drain cleaner further includes a handle assembly coupled to and extending rearwardly from the shroud. The handle assembly includes a motor, a grip, and an actuator to selectively energize the motor. The actuator is positioned in an area defined between the grip and the shroud.

Drain cleaner

A drain cleaner includes a shroud with a closed end and an open end opposite the closed end, a drum assembly positioned within the shroud and rotatable relative to the shroud, a flexible cable stored within the drum assembly, and a handle assembly coupled to and extending rearwardly from the shroud. The handle assembly includes a motor, a grip, and an actuator to selectively energize the motor. The actuator is enclosed between the grip and the shroud.

System for cooling a power tool. One exemplary power tool includes a housing including an air intake and an air exhaust. The power tool further includes a motor and a fan configured to pull cooling air into the housing through the air intake, and exhaust the cooling air out of the housing through the air exhaust. The power tool further includes a plurality of field-effect transistors (FETs). The FETs couple the stator coils to a power source. The power tool further includes a FET board within the housing. The power tool further includes a heat sink within the housing. The heat sink includes a first mounting portion and a second mounting portion. Each of the mounting portions includes a horizontal fin extending toward a respective side of the housing. A plurality of vertical fins extends from a top surface of each of the horizontal fins.

A drain cleaner includes a handle assembly with a grip, a motor supported by the handle assembly, and a shroud coupled to and extending forwardly from the handle assembly. The shroud includes a closed end facing the handle assembly and an open end facing away from the handle assembly. The drain cleaner also includes a drum assembly rotatably coupled to the handle assembly and positioned within the shroud. The drum assembly is operable to be rotated by the motor relative to the handle assembly and the shroud. The drain cleaner further includes a flexible cable stored within the drum assembly. The drum assembly encloses the flexible cable.

A drain cleaner includes a handle assembly having a grip, a motor positioned within the handle assembly, and an actuator supported by the handle assembly adjacent the grip. The actuator is electrically coupled to the motor and operable to selectively energize the motor. The drain cleaner also includes a shroud fixed to and extending forwardly from the handle assembly. The shroud includes a closed end adjacent the handle assembly. The drain cleaner further includes a drum assembly rotatably coupled to the handle assembly and positioned within the shroud. The drum assembly is operable to be rotated by the motor relative to the handle assembly and the shroud. The drain cleaner also includes a flexible cable stored within the drum assembly. The flexible cable is configured to be extended out of the drum assembly and into a drain.
