  • Patent number: 12649211
    Abstract: A belt sander for sanding a workpiece including a main housing, a motor having a motor shaft disposed within the main housing, and a handle extending from the motor housing and configured to be grasped by a user for maneuvering the belt sander. The motor shaft defines a motor axis that is perpendicular to a handle axis of the handle. The belt sander further includes a contact arm that extends from the motor housing and is moveable between a stowed position and a deployed position, and a light assembly coupled to the motor housing. The light assembly includes a light housing, an LED, and a lens coupled to the light housing for diverging light rays from the LED across a light range. When the contact arm is in the deployed position, the light range illuminates at least a portion of the contact arm and a space below the contact arm.

  • Publication number: 20250229375
    Abstract: A polishing tool includes a housing having a motor housing portion with a motor therein and a handle portion extending rearwardly therefrom, the motor housing portion having a tapered profile along a length of the motor housing the motor is positioned within, the motor housing portion defining a second width proximate a rear end of the motor housing portion and a third width, greater than the second width, adjacent a front end of the motor housing portion, a trigger proximate the handle portion and configured to selectively activate the motor, a battery pack coupled to the handle portion and configured to provide electrical power to the motor, and a backing plate coupled to the motor to receive torque therefrom, causing the backing plate to move in a rotating and/or orbiting manner. The motor housing portion includes a maximum width two times or less a maximum width of the handle portion.

  • Publication number: 20220168863
    Abstract: A polishing tool includes a housing having a motor housing portion and a handle portion extending rearwardly therefrom, a motor located within the motor housing portion, a trigger proximate the handle portion and configured to selectively activate the motor, a battery pack coupled to the handle portion of the housing and configured to provide electrical power to the motor when the trigger is actuated, and a backing plate coupled to the motor to receive torque therefrom, causing the backing plate to move in one or more of a rotating manner and an orbiting manner. The motor housing portion includes a maximum width of two times or less than a maximum width of the handle portion.
