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.

The present disclosure relates to a drill tool (1), such as a core drill tool (1), comprising a motor unit (2) and a gear unit (3). The motor unit (2) comprises an electric motor (4) and a motor drive shaft (5) that extends along a first longitudinal axis (6) from the electric motor (4) and protrudes out of a motor unit housing (7) via a motor exit aperture (8) in a housing end part (9) and comprises a drive shaft gear (10). The drive shaft gear (10) is adapted to propel a drill shaft (14) that extends along a second longitudinal axis (15) and comprises a tool holder (16) that is adapted to hold a tool. The housing end part (9) comprises a wall part (17) arranged transversally to the longitudinal axes (6, 15) and is adapted to close the gear unit cavity (11) and to separate the electric motor (4) from the gear unit cavity (11).

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.

A reciprocating tool includes a motor, a reciprocating member, and a crank mechanism. The motor is disposed in a housing. The reciprocating member projects from the housing. The crank mechanism converts rotation of a rotation shaft of the motor into reciprocation of the reciprocating member. The crank mechanism rotates around an axis in a lateral direction by rotation transmission from the rotation shaft, and the crank mechanism includes a crank member having an eccentric pin, a connecting rod coupling the eccentric pin to the reciprocating member, and a balancer coupled to the eccentric pin, and the balancer is supported by the eccentric pin alone in the housing.

A drill (1) for drilling railway sleepers comprises a support structure (2), a motor unit (3) supported by the support structure (2), a handle (4) connected to the support structure (2), at least one control member (5) arranged at the handle (4) for actuating the motor (3), a spindle (7) supported by the support structure (2) and operable by the motor (3), to rotate about a spindle axis (16), wherein a drilling tip (8) can be coupled to said spindle, a protective casing (11) connected to the support structure (2) and sliding in the direction of the spindle axis (16) between an axially protracted position, in which it envelops the tip (8) and an axially retracted position, in which the tip (8) protrudes from the protective casing (11), wherein the handle (4) comprises two gripping portions (36, 37), for the user's two hands, situated on two diametrically opposite sides of the drill (1) with respect to the spindle axis (16), and the motor unit (3) comprises an electric motor which can be powered by means of a rechargeable and replaceable battery (6).

An electric tool includes a housing, a motor, a power output assembly, and a switching member. The housing is provided with a first air outlet and a second air outlet. The power output assembly is connected to the motor. The switching member is capable of rotating in the housing, and the switching member is provided with a third air outlet and a fourth air outlet. The switching member is capable of rotating to a first position and a second position in the housing. When the switching member rotates to the first position, the first air outlet is in communication with the third air outlet and the fourth air outlet is closed by the housing. When the switching member rotates to the second position, the second air outlet is in communication with the fourth air outlet and the third air outlet is closed by the housing.

A removable attachment assembly for an angular drill assembly, which includes a base member and a securement assembly secured to the base member for releasably securing the base member to a housing of the angular drill assembly. The removable attachment assembly further includes a cushion member associated with the base member.

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 range of power tools each includes motor and transmission housings with an electric motor and a transmission mechanism mounted respectively therein, with the transmission mechanism using the rotary output of the motor to drive a cutting tool. An intermediate housing is sandwiched between the motor and transmission housings. Each of the motor housings is the same in shape, and the length of the electric motors in each of the power tool is different to the length of the electric motors in the other power tools in the range. The transmission housing is positioned differently relative to the motor housing in each power tool to accommodate the difference in length in the electric motor in that power tool, the shape of the intermediate housing in each power tool varying relative to the other intermediate housings to accommodate the difference positions of the transmission housings relative to the motor housings.
