The present disclosure relates generally to a machining tool and method for using the machining tool. The machining tool includes a machining arm including a first arm section, a second arm section, a proximate end, a distal end, and a machining arm longitudinal axis, a belt disposed around the machining arm; and a first motor operably coupled to the machining arm, wherein at least a portion of the machining arm is configured to pivot such that an angle is formed between the distal end and the machining arm longitudinal axis. The method includes the steps of placing the pivotable machining arm in a first orientation, inserting the pivotable machining arm in the desired location, determining whether the belt is in a desired position relative to the raised surface, operating the motor to rotate the belt around the pivotable machining arm, and placing the belt in contact with the raised surface.

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.

A dust box is provided that is configured to be removably mounted to a belt sander having a housing, and a discharge nozzle and a suction nozzle that are connected to the housing. The dust box has a first nozzle configured to be connected to the discharge nozzle, a second nozzle configured to be connected to the suction nozzle, a container part formed of synthetic resin and connected to the first and second nozzles, and a filter. The filter is configured to separate dust from air. The filter is provided within the container part to partition an inside space of the container part into a first space that communicates with the first nozzle and a second space that communicates with the second nozzle.

A belt sander has an electric motor, a housing including a motor housing part, belt driving part, first handle and battery mounting part. Where a direction in which a rotational axis of the drive roller and the driven roller extend is a left-right direction, a direction wherein the rollers are arranged in parallel is a front-rear direction, and a direction orthogonal to the left-right and front-rear directions is an up-down direction, the belt driving part is below the motor, and a polishing surface is defined by a lower surface of the sanding belt. The battery mounting part is configured so a battery can be mounted and removed by being slid in a sliding direction. The mounting part overlaps with the polishing surface viewed from above and overlaps with the motor viewed from the front. The sliding direction of the battery is a horizontal direction including the front-rear and left-right directions.

A handheld belt sander with improved structure includes a main body having a rotating wheel and a mount. A support rod with a front roller is disposed on the mount. A support member with a rear roller is disposed on the mount. A tightened grinding belt encircles the rotating wheel, the front roller and the rear roller. A space is formed between the support rod and a part of the grinding belt between the front roller and the rear roller so that the grinding belt moves into the space after being pressed. Two side rollers are disposed on two sides of the support member to be adjacent to the grinding belt and are separated from the grinding belt by a gap in order to block the grinding belt from separating from the rear roller.

A protective cover assembled on an abrasive belt hand tool. The protective cover comprises an annular base and a tightening component. The annular base comprises a notch, a first clamping arm positioned on one side of the notch, and a second clamping arm positioned on the other side. The first clamping arm is formed with a through hole, the second clamping arm is formed with an assembly hole, the assembly hole does not penetrating through the second clamping arm. The annular base comprises a first state for tightening a protective cover mounting portion when the first clamping arm and the second clamping arm narrow the notch, and the annular base comprises a second state that the first clamping arm and the second clamping arm do not narrow the notch. The tightening component comprises a pull rod penetrating through the through hole and a piece arranged on the pull rod.
