摘要： A screw driving includes a housing, a motor, a spindle, a locator, a first detecting mechanism and a controller. The locator is mounted on a front end portion of the housing so as to be movable in a front-rear direction relative to the housing and configured to define a depth to which a screw is driven into a workpiece. The first detecting mechanism is configured to detect a position of the locator in the front-rear direction. The controller is configured to control driving of the motor. Rotational driving of the spindle in a forward direction is started in response to the spindle being pressed rearward, and the rotational driving of the spindle in the forward direction is stopped when the first detecting mechanism detects that the locator is disposed in a specified position rearward of a most forward position within a moving range of the locator.

摘要： A paint multi-tool assembly includes a shaft that has a hooked end that is insertable into a power tool thereby facilitating the shaft to be rotated when the power tool is turned on. A first cylinder insertably receives the shaft thereby facilitating the first cylinder to be inserted into an open end of a paint roller. Thus, the power tool can rotate the paint roller for cleaning paint off of the paint roller. A plurality of fins is each coupled to and extends away from the first cylinder for stirring paint in the paint container. A second cylinder is coupled to each of the fins such that the second cylinder is spaced from the first cylinder. In this way the second cylinder can be inserted into the paint container or be inserted into the open end of the paint roller.

摘要： A drill guide for a drill bit of a hand-held drill is disclosed. The drill guide includes a mount, a telescoping guard, and a guide foot. The mount is configured to couple to a non-rotating portion of the hand-held drill. The telescoping guard extends from the mount and is configured to telescope into a retracted position from an extended position. The guide foot is coupled to the telescoping guard opposite the mount such that the drill guide enshrouds the drill bit when the telescoping guard is in the extended position, and the drill bit passes through the guide foot as the telescoping guard telescopes into the retracted position from the extended position.

摘要： Example alignment systems for aligning a drill bit with respect to a gang channel and methods of use are described herein. An example alignment system for use with a drill includes a drill block having a guide portion and an attachment portion. The attachment portion is configured to be removably coupled to a foot of the drill such that the drill block is positioned between the foot and a drill bit of the drill. A longitudinal axis of the drill block is coaxial with a longitudinal axis of the drill bit when the attachment portion is coupled to the foot. The guide portion is configured to at least partially contact an inner surface of opposing legs of a gang channel to thereby center the drill bit between the opposing legs of the gang channel.

摘要： A tool with a transmission assembly having a reduction gearset and a speed selector. The speed selector has a member, an actuator and a shifter assembly. The member is movable between a first position, in which the member is non-rotatable, and a second position in which the member is coupled to a planet carrier of the reduction gearset for common rotation. The actuator includes a pivoting yoke and a follower that is coupled to the yoke. The follower engages the member so as to be axially movable with the follower. The shifter assembly has a selector switch, a switch fork, and a pair of springs. The selector switch is slidable between a first switch position and a second switch position. The switch fork is slidably coupled to the selector switch and receives the yoke. The springs cooperate to bias the switch fork relative to the selector switch into a neutral position.
