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.

Concrete vibrator for use in backpack and stationary configurations

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.

A cut-off saw configured to remove material from a workpiece, the cut-off saw includes a motor, a blade, a drive assembly, a handle, and a coating. The blade is capable of removing material from the workpiece upon contact between the blade and the workpiece. The drive assembly is coupled to the motor and the blade and is configured to transmit torque from the motor to the blade. The handle is configured to be grasped by a user, and includes a surface and a first material having a first surface resistivity. The coating covers at least a portion of the handle. The coating is configured to distribute static electricity away from the surface. The coating is made of a second material having a second surface resistivity less than the first surface resistivity.
