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.

A housing for an electric machine tool, in particular for a core drill, said housing in which a motor is accommodated, which has a motor shaft for driving a tool mount and to which cooling air is supplied through at least one air guide duct, which is delimited at one end by at least one air inlet and at the other end by at least one air outlet. A guide structure, providing air guidance for the cooling air and associated with a motor mount, in which the motor is at least partially accommodated, is disposed in the air guide duct downstream from the at least one air inlet.

A newly configured centerpoint drill and a drill attachment device that can be attached to a conventional cordless drill include configurations that require a user's hand to be in direct alignment with the keyless chuck of the drill to enable a user or operator to apply maximum pressure or force during use of a drill to reduce time and effort spent by a user/operator.

A pneumatic tool with changeable exhaust direction includes a tool main body and a direction change assembly. The tool main body includes a housing portion having a first exhaust channel. The direction change assembly includes an air guidance member and an adjustment member. The air guidance member is mounted onto the housing portion, and a second exhaust channel is formed with the air guidance member. The adjustment member is installed with a sealing ring. The adjustment member generates an axial movement relative to the air guidance member and along a first axis to move away from the air guidance member in order to open the second exhaust channel or to allow the sealing member to abut against the air guidance member in order to close the second exhaust channel. Accordingly, the exhaust direction is adjustable during the use of the pneumatic tool in order to facilitate different processing operations.

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.

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.

A power tool and method for heat management using speed control. The power tool includes a housing, a motor within the housing, and an electronic processor coupled to the motor. The electronic processor is configured to operate the motor at a first speed corresponding and determine whether the power tool has been unloaded for a predetermined amount of time during which the motor has been operated at the first speed. In response to determining that the motor has been unloaded for the predetermined amount of time, the electronic processor operates the motor at a second speed lower than the first speed. The electronic processor further determines whether the power tool is loaded while operating the motor at the second speed and operates the motor at the first speed in response to determining that the motor is loaded.

A tool hanging system. The tool hanging system includes a power tool having a mount receiving portion. A mounting attachment is engaged with the mount receiving portion. The mounting attachment includes a first portion adjacent to the power tool and an overhang portion spaced apart from and opposite the first portion. A groove is located between the first portion and the overhang portion. The mounting attachment also includes a peg board projection, the peg board projection projecting away from the power tool and past the overhang portion. The peg board projection engages with a pegboard.

A newly configured centerpoint drill and a drill attachment device that can be attached to a conventional cordless drill include configurations that require a user's hand to be in direct alignment with the keyless chuck of the drill to enable a user or operator to apply maximum pressure or force during use of a drill to reduce time and effort spent by a user/operator.

A power tool is provided including a motor housing; a transmission housing disposed adjacent the motor housing with a gap therebetween; an electric motor including a rotor and a stator mounted within the motor housing; and an intermediate housing disposed between the electric motor and the transmission mechanism. The intermediate housing includes a back wall extending radially adjacent an axial end of the stator and having a through-hole therein through which the motor spindle extends; side walls extending axially from an outer circumference of the back wall internally of the motor housing; and one or more external walls extending substantially-radially outwardly from axial end of the one or more side walls to fill a gap formed between the transmission housing and the motor housing in the axial direction.
