Abstract: A powered fastener driver includes a first cylinder, a first piston positioned within the first cylinder, a second cylinder in fluid communication with the first cylinder, and a second piston positioned within the second cylinder. The first piston is moveable between a top-dead-center position and at or near a bottom-dead-center position and the second piston is moveable between a top-dead-center position and a bottom-dead-center position to initiate a fastener driving cycle. A drive blade is coupled to the second piston for movement therewith and a drive mechanism is configured to drive the first piston between the top-dead-center position and at or near the bottom-dead-center position. The drive mechanism includes a crank arm that rotates less than 360 degrees for moving the first piston from at or near the bottom-dead-center position and the top-dead-center position and then back to at or near the bottom-dead-center position to complete the fastener driving cycle.

Abstract: A rotary tool including a tool body defining an axis extending between a rear end and an opposite working end, a motor configured to receive power from a power source, a drive shaft coupled to the motor with the motor, a chuck coupled to the drive shaft, and an axial adjustment mechanism. The axial adjustment mechanism includes an adjustment shaft having an axial end defining a floor of the chuck, where the floor limits an insertion depth within the chuck, and where the adjustment shaft is movable in a direction parallel to the axis between a first position defining a first insertion depth and a second position defining a second insertion depth.

Abstract: A rotary tool includes a housing, a drive shaft positioned within the housing, and a bit holder. The bit holder is positioned adjacent a distal end of the housing and is driven by rotation of the drive shaft. The rotary tool also includes a wrench assembly for adjusting the bit holder and a light source configured to emit light in a direction toward the bit holder. The wrench assembly is positioned adjacent the bit holder and is movable between a first position and a second position. The wrench assembly is coupled to the housing and disengaged from the bit holder assembly in the first position and is engaged with the bit holder assembly in the second position.

Abstract: A rotary tool includes a housing, a drive shaft positioned within the housing, and a bit holder. The bit holder is positioned adjacent a distal end of the housing and is driven by rotation of the drive shaft. The rotary tool also includes a wrench assembly coaxially movable along the longitudinal axis and selectively engageable with the bit holder, a groove positioned on one of the housing and the wrench assembly, and a protrusion positioned on the other of the housing and the wrench assembly. The protrusion engages the groove and retaining the wrench assembly against axial movement while the wrench assembly is in a first position, and the protrusion is axially spaced apart from the groove while the wrench assembly is in a second position.

Abstract: A method for controlling a motor of a power tool including performing a load test on a battery pack of the power tool, determining, via a first controller, a first mechanism control scheme based on the load test, receiving, via the first controller, a user input indicative of beginning an operation cycle of the power tool, and isolating the first controller from a second controller. The method further including controlling, via the first controller, the motor based on the first mechanism control scheme, sensing a dataset indicative of a result of the operation cycle based on the first mechanism control scheme, receiving, via the second controller, the dataset, connecting the first controller to the second controller upon completion of the operation cycle, transmitting, via the second controller, the dataset to the first controller, and determining, via the first controller, a second mechanism control scheme based on the dataset.
