Abstract: A power tool includes a housing with a motor housing portion and a drive housing portion, a handle extending from the housing and defining a gap between the handle and the housing, a motor located within the motor housing portion having a motor output shaft, a fan coupled to the motor output shaft, a battery to provide power to the motor, a trigger coupled to the handle and manipulable to energize the motor, a spindle extending within the drive housing portion and driven by the motor output shaft to rotate about an axis, and a fluid delivery system configured to supply a fluid to the spindle. The housing includes an air intake opening and a deflector to inhibit the fluid from entering the housing through the air intake opening, and rotation of the fan draws an airflow into the housing through the air intake opening.

Abstract: A power tool includes a housing, a motor, a spindle, a handle holder and an auxiliary handle. The housing includes a motor housing portion, a drive housing, and a mounting portion between the motor housing portion and the drive housing. The motor is located within the motor housing portion. The spindle is configured to rotate about a rotational axis in response to torque received from the motor. The handle holder is coupled to the drive housing and defines a first mounting point, and the mounting portion defines a second mounting point. The auxiliary handle is selectively attachable to each of the first and second mounting points, and the first mounting point is located at a first position along the rotational axis, and the second mounting point is located at a second position offset from the first position in a direction along the rotational axis.

Abstract: A rotary power tool comprises a drive mechanism, a spindle rotatable about a rotational axis in response to receiving torque from the drive mechanism, and a first shank coupled for co-rotation with the spindle and having a first diameter. The first shank includes a first threaded portion upon which a first tool bit is receivable. A second shank is coupled for co-rotation with the spindle and extends outwardly from and coaxial with the first shank. The second shank has a second diameter that is smaller than the first diameter and a second threaded portion upon which a second tool bit is receivable.

Abstract: A power tool includes a housing, a motor supported within the housing, a handle extending from the housing, a trigger, a spindle, and a fluid delivery system. The handle defines a gap between the handle and the housing, and the trigger, coupled to the housing, is manipulable to energize the motor. The spindle is configured to rotate about a rotation axis in response to torque received from the motor, and the fluid delivery system is configured to supply fluid to the spindle. The fluid delivery system includes a valve operable to regulate a flow of fluid to the spindle, and the valve includes an actuator disposed within the gap.

Abstract: A rotary power tool includes a main housing and a transmission housing coupled to the main housing. The transmission housing includes a bearing pocket open to a front of the transmission housing and defined at least partially by a radially inward-extending flange. The rotary power tool also includes an output shaft and a bearing positioned within the bearing pocket adjacent and in abutting relationship with the radially inward-extending flange for rotatably supporting the output shaft in the transmission housing. The rotary power tool also includes a radially outward-extending flange on the output shaft that radially overlaps at least a portion of the bearing on an opposite side of the bearing as the radially inward-extending flange. A line of action of an axial reaction force applied to the output shaft is directed to the transmission housing via the radially outwardly-extending flange, the bearing, and the radially inward-extending flange.

Abstract: A concrete vibrator includes a frame, a strap coupled to the frame, a main housing supported upon the frame, and an electric motor coupled to the main housing. The concrete vibrator further comprises a flexible shaft having a first end coupled to the motor and an opposite, second end. The concrete vibrator further comprises a vibrator head coupled to the second end of the shaft, the vibrator head configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The concrete vibrator is operable in a backpack configuration in which the strap is used to carry the concrete vibrator with the frame in a vertical orientation, and in a briefcase configuration in which the frame is supportable in a horizontal orientation.

Abstract: A cart for carrying a cut-off saw having a saw blade. The cart includes a frame with upper and lower portions, a wheel arm pivotably coupled to the lower portion about a first axis, and a rear wheel assembly coaxial with the first axis and coupled to the frame and the wheel arm. The cart includes a front wheel coupled to an end of the wheel arm opposite the rear wheel assembly, an adjustment lever pivotably coupled to the upper portion about a second axis, and a link having a first end pivotably coupled to the adjustment lever and spaced from the second axis, and a second end pivotably coupled to the wheel arm between the first axis and the front wheel. Pivoting the adjustment lever about the second axis pivots the wheel arm about the first axis to adjust a vertical position of the front wheel relative to the upper portion.
