A power tool includes a motor housing and a motor supported within the motor housing. The motor includes an output shaft defining an axis. The power tool also includes a bearing configured to support the output shaft for rotation about the axis, an end cap removably coupled to the motor housing, and a bearing retainer integrally formed with the end cap. The bearing retainer is configured to axially and radially secure the bearing to the end cap.

Bearing retainer for a power tool

A power tool having multiple wireless communication states and a method of wirelessly communicating by a power tool. The power tool includes a motor, a battery pack interface that selectively receives a battery pack, a backup power source, and a wireless communication controller coupled to the backup power source and the battery pack interface. The wireless communication controller operates in a connectable state when coupled to a battery pack and transmits tool operational data to the external device and receives tool configuration data from the external device. The wireless communication controller operates in an advertisement state when the wireless communication controller is coupled to and powered by the backup power source. In the advertisement state, the wireless communication controller is configured to transmit the unique tool identifier. The external device may also display an indication of the communication state of the power tool.

Power tool and method for wireless communication

An impact tool includes a housing having a motor housing portion and an impact housing portion. The impact housing portion has a front end defining a front end plane. An electric motor is supported in the motor housing, a battery pack is supported by the housing for providing power to the motor, and a drive assembly is supported by the impact housing portion. The drive assembly includes an anvil extending from the front end of the front housing portion with an end defining an anvil end plane. The drive assembly also includes a hammer rotationally and axially movable relative to the anvil for imparting the consecutive rotational impacts upon the anvil, and a spring for biasing the hammer in an axial direction toward the anvil. A distance between the front end plane and the anvil end plane is greater than or equal to 6 inches.

Impact tool

A side handle assembly comprises a handle configured to be gripped by a user, a rod coaxially coupled the handle and rotationally fixed to the handle, and a clamp coupled to the rod. The clamp includes a flexible band enclosing an area and having a first end and a second end, a first connection block coupled to the first end of the flexible band, and a second connection block coupled to the second end of the flexible band. The rod includes an annular shoulder abutted with the first connection block and a threaded portion received within a threaded bore of the second connection block. In response to the handle being rotated in a first direction, the second connection block is moved closer to the first connection block along the threaded portion of the rod, decreasing the area enclosed by the flexible band.

Side handle for power tool

An auxiliary handle is for use with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, and a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch. When the first protrusion of the first clamp engages the first notch, the second clamp is movable along the shaft between a first position, in which the second protrusion engages the second notch, and a second position, in which the second protrusion is disengaged from the second notch. The auxiliary handle also includes a grip coupled to the shaft. When the grip is rotated relative to the second clamp, the second clamp is moved from the second position toward the first position.

Power tool dust collector

An electrical combination including a power tool and a battery pack. The power tool includes power tool terminals. The battery pack is configured to be interfaced with the power tool. The battery pack includes a battery pack housing, at least three terminals, and a plurality of battery cells. The battery pack terminals include a positive terminal, a negative terminal, and a sense terminal. The at least three terminals are configured to be interfaced with the power tool terminals. The plurality of battery cells are arranged within and supported by the battery pack housing. Each of the battery cells has a lithium-based chemistry and a respective state of charge, and power is transferable between the battery cells and the power tool. A circuit is configured to monitor the battery cells, detect a charge imbalance among the battery cells, and prevent the battery pack from operating when the charge imbalance is detected.

Lithium-based battery pack

A method for conducting an operation including a power tool battery pack. The battery pack can include a housing, a first cell supported by the housing and having a voltage, and a second cell supported by the housing and having a voltage. The battery pack also can be connectable to a power tool and be operable to supply power to operate the power tool. The method can include discharging one of the first cell and the second cell until the voltage of the one of the first cell and the second cell is substantially equal to the voltage of the other of the first cell and the second cell.

A side handle assembly comprises a handle configured to be gripped by a user, a rod coaxially coupled at a first end to the handle, the rod rotationally fixed to the handle, and a mounting assembly. The mounting assembly includes a first tool interface with a through bore, the first tool interface configured to accept a clamping shaft within the through bore, a second tool interface with a threaded bore, the second tool interface configured to accept a threaded portion of the clamping shaft within the threaded bore, and an orientation adjustment mechanism coupling a second end of the rod to the mounting assembly and configured to adjust an orientation of the rod and handle with respect to at least one of the first tool interface or the second tool interface of the mounting assembly.

An electrical combination. The electrical combination comprises a battery pack configured to be interfaced with a hand held power tool, a control component, and a semiconducting switch. The transfer of power from the battery pack to the hand held power tool is controlled by the control component and the switch based on one of a battery pack state of charge and a respective state of charge of one of a plurality of battery cells. A discharge current of the battery pack is regulated based on the switch being controlled into one of a first state and a second state by the control component to selectively enable the transfer power from the plurality of battery cells to the hand held power tool.

Lithium-based battery pack for a hand held power tool

An auxiliary handle can be used with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch, and a grip coupled to the shaft. When the first protrusion of the first clamp engages the first notch and the grip is rotated relative to the second clamp, the second clamp is moved toward the first clamp, such that the first protrusion engages the first notch and the second protrusion engages the second notch to couple the auxiliary handle to the housing of the power tool.
