An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a hub selectively engagable with the spindle to lock the accessory to the power tool, and a sleeve slidable along the arms between a first position and a second position, where the sleeve includes a plurality of apertures through which the corresponding plurality of arms extend. When the sleeve is in the first position the sleeve locks the hub to the spindle to secure the accessory to the power tool, and wherein when the sleeve is in the second position the sleeve disengages the hub from the spindle to release the accessory from the power tool.

Attachment mechanism for a power tool

An example power tool includes a battery pack receiving portion including a battery pack compartment including a battery pack support structure configured to receive and support a battery pack including battery terminals. The power tool further includes a terminal block located in the battery pack receiving portion and including tool terminals. At least two terminals of the tool terminals are configured to electrically and physically couple to the battery terminals. The power tool further includes an insertable device compartment located in the battery pack receiving portion and configured to receive an insertable wireless communication device including a first electronic processor, a transceiver, and device terminals. At least one device terminal is configured to electrically and physically couple to at least one shared terminal of the at least two terminals of the tool terminals. The insertable wireless communication device is configured to wirelessly communicate with an external device.

Power tool with shared terminal block

An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a ball detent selectively engagable with the spindle to lock the accessory to the power tool, a sleeve slidable along the arms between a first position in which the sleeve biases the ball detent into engagement with the spindle to axially secure the accessory to the tool, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the tool, and a second mating member coupled to the arms of the housing.

An accessory for use with a rotary power tool having a rotatable spindle and a first mating member. The accessory includes a housing having a body and a plurality of arms extending therefrom, a hub rotatably supported within the housing between the arms and configured to be coupled to the spindle to receive torque therefrom, a ball detent disposed within the hub and selectively engagable with the spindle to axially lock the accessory to the power tool, a sleeve axially slidable along the arms and relative to the hub between a first position in which the sleeve biases the ball detent radially inward and into engagement with the spindle when coupled to the hub to axially secure the accessory to the tool, and a second position in which the ball detent is disengageable from the spindle to release the accessory from the tool, and a second mating member axially fixed to the arms of the housing, wherein the sleeve is slidable between the second mating member and the body of the housing, and wherein the first and second mating members are engaged when the accessory is axially secured to the tool to rotationally fix the accessory to the tool.
