Abstract: A core drill includes a housing, a first handle extending from the housing and defining a gap between the handle and the housing, a motor supported within the housing, and a battery removably coupled to the housing and configured to provide power to the motor. The battery has an output voltage greater than 40 volts. The core drill further includes a spindle configured to rotate about a rotational axis in response to torque received from the motor and a fluid delivery system 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 an auxiliary handle removably coupleable to the housing at each of a first mounting point and a second mounting point.

Abstract: An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.

Abstract: A clutch mechanism, for use in a rotary power tool having a motor, comprises an input member to which torque from the motor is transferred and an output member co-rotatable with the input member, the output member defining a rotational axis. The clutch mechanism further comprises a cam surface formed on one of the input member or the output member and a compression spring carried by the other of the input member or the output member for co-rotation therewith. The clutch mechanism also comprises a follower having a circular cross-sectional shape biased against the cam surface by the compression spring. In response to relative rotation between the input member and the output member, the cam surface displaces the follower along a line of action coaxial or parallel with the spring. The line of action does not intersect the rotational axis.

Abstract: A concrete vibrator includes a housing, a handle, an electric motor, a flexible shaft, a vibrator head, and a battery pack. The handle extends from the housing. The electric motor is coupled to the housing. The flexible shaft has a first end coupled to the motor and an opposite, second end. The vibrator head is coupled to the second end of the shaft. The vibrator head is configured to receive torque from the motor and the shaft to cause the vibrator head to vibrate. The battery pack is coupled to a battery receptacle defined on the housing. The battery pack is configured to provide electric power to the electric motor to drive the motor and the shaft. The concrete vibrator is operable in a briefcase configuration in which the handle is used to carry the concrete vibrator with the housing supported 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.
