Abstract: A power tool includes a housing, a motor positioned within the housing, and an impulse assembly coupled to the motor to receive torque therefrom. The impulse assembly includes a cylinder at least partially forming a chamber containing a hydraulic fluid, an anvil positioned at least partially within the chamber, and a hammer positioned at least partially within the chamber. The hammer includes a first side facing the anvil and a second side opposite the first side. The impulse assembly further includes a biasing member biasing the hammer towards the anvil, and a valve movable between a first position that permits a first fluid flow rate of the hydraulic fluid in the chamber from the second side to the first side, and a second position that permits a second fluid flow rate of the hydraulic fluid in the chamber from the first side to the second side.

Abstract: A pipe cutter for cutting a pipe includes a cutting head assembly having a first carriage and a second carriage spaced apart to define a cutting area. The first carriage supports a cutting mechanism, and the second carriage is configured to support a pipe within the cutting area. The carriages have a locked state and an unlocked state such that when the carriages are in the unlocked state, the carriages are movable relative to each other and biased into the cutting area. The pipe cutter also includes a drive assembly configured to rotate the cutting head assembly and a locking mechanism configured for changing the carriages from the unlocked state to the locked state and for holding the carriages in the locked state. The locking mechanism includes an actuation member rotatably coupled to the first carriage.

Abstract: A chuck includes a chuck body extending along a longitudinal axis, the chuck body including a plurality of slots each arranged at an oblique angle with respect to the longitudinal axis. A plurality of jaws each includes a first engagement portion, a jaw end, and a drive end. Each of the jaws is disposed within one of the plurality of slots and is movable between a close position and an open position. A biasing member is coupled to the plurality of jaws and is operable to bias the plurality of jaws toward the close position and a rotating assembly is selectively engageable with the plurality of jaws such that when engaged, the plurality of jaws are movable in response to rotation of the rotating assembly.

Abstract: A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the handle, and a drive unit positioned in the drive unit support portion. The drive unit includes an output shaft extending at least partially through the handle portion. The power tool also includes a ball screw mechanism having a nut supported at least partially within the inner housing and a screw coupled to the nut for relative axial displacement therewith in response to relative rotation between the screw and the nut. Torque from the output shaft is applied to one of the nut and the screw to cause the relative rotation. The handle portion exerts a reaction torque on the inner housing in response to the relative rotation between the nut and screw to prevent the inner housing from rotating relative to the outer housing.

Abstract: A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, and an anvil received within the spindle for reciprocation in response to reciprocation of the piston. The anvil imparts axial impacts to a tool bit in response to reciprocation of the piston. The rotary hammer also includes a bit retention assembly for securing the tool bit to the spindle.

Abstract: A power tool having a housing, a motor, a tool holder driven about an output axis by the motor, and an output element for performing an operation on a workpiece. The tool holder has a locating feature including a tapered portion becoming narrower in a direction away from the surface of the tool holder. The output element has an aperture for receiving the locating feature and a face facing the surface of the tool holder when the locating feature is received. The power tool also includes a flange for transferring a clamping force for urging the output element towards the tool holder and a tab projecting from the flange for finger tightening the flange. A biasing member provides the clamping force toollessly. A gap is defined between the surface of the tool holder and the face when the tapered portion of the locating feature is fully received in the aperture.
