    Abstract: A hammer drill includes a housing, a first ratchet fixed to the housing, a spindle rotatably supported by the housing about an axis, and a second ratchet coupled for co-rotation with the spindle. The second ratchet is engageable with the first ratchet in response to rearward displacement of the spindle to impart a hammering action on the spindle. The hammer drill further includes a thrust bearing having an arm extending away from the axis, and a selector ring having a post extending toward the arm. The selector ring is rotatable between a first position in which the post is engageable with the arm to limit the rearward displacement of the spindle and prevent engagement of the first and second ratchets, and a second position in which the post is misaligned with the arm to permit the rearward displacement of the spindle and engagement of the first and second ratchets.

    Abstract: A transmission for a power tool includes an intermediate shaft and first and second driving gears coupled for co-rotation with the intermediate shaft. The transmission also includes an output shaft having first and second driven gears continuously engaged with the respective first and second driving gears. The transmission further includes a hub coupled for co-rotation with the output shaft, and a collar. The collar is axially movable along the output shaft between a first position in which the collar couples the first driven gear to the hub for co-rotation with the output shaft, and a second position in which the collar couples the second driven gear to the hub for co-rotation with the output shaft.

    Abstract: A multi-stage planetary transmission includes a transmission housing and a first planetary stage at least partially positioned in a transmission housing. The first planetary stage includes a first stage ring gear, a first stage carrier, and a plurality of first stage planet gears supported by the first stage carrier. A motor output pinion is engaged with each of the first stage plant gears. The transmission further includes a second planetary stage positioned downstream of the first planetary stage to receive torque from the first planetary stage and a shift mechanism operable to move the first stage ring gear between a first position, in which the first stage ring gear is rotatably fixed relative to the transmission housing for enabling the first planetary stage, and a second position, in which the first stage ring gear is coupled for co-rotation with the first stage carrier for disabling the first planetary stage.

    Abstract: A shoe for a band saw, the shoe having a body including a generally C-shaped member defined by a substantially planar portion for engaging a workpiece and a pair of rails extending transversely therefrom and wrapping such that the body includes a generally T-shaped receptacle for slidably receiving a correspondingly-shaped member. The substantially planar portion includes apertures aligned linearly. A biased detent feature has a holding force with a magnitude sufficient to hold the body when the detent feature is seated in one of the apertures. The body is moveable linearly, relative to the detent feature, in the direction of alignment of the apertures between engaged and non-engaged positions. The body is moveable out of the engaged position in the direction by application of a disengaging force in the direction acting to move the body with respect to the detent feature and acting to overcome the holding force in the engaged position.

    Abstract: A brushless direct current motor for a power tool. The motor includes a stator assembly including a stator core having stator laminations with an annular portion and inwardly extending stator teeth. The motor also includes a rotor assembly including a rotor core having rotor laminations and defining a central aperture that receives an output shaft. The rotor assembly also includes a rotor end cap on a first side of the rotor core having a bearing holder and defining a channel, wherein the channel is open on a side of the rotor end cap facing the rotor core. The motor further includes a bearing provided in the bearing holder that couples the rotor end cap to the output shaft and a position sensor board assembly provided in the channel of the rotor end cap and configured to provide position information of the rotor core to a motor controller.

    Abstract: A band saw includes a first wheel and a second wheel for supporting a continuous band saw blade, a motor operable to drive at least one of the first and second wheels, a housing supporting the first wheel and the second wheel, a shoe for engaging a workpiece, the shoe including a first detent feature. The band saw also includes a second detent feature cooperating with the first detent feature to hold the shoe with respect to the housing. The shoe is moveable with respect to the housing between an engaged position and a non-engaged position. The shoe is moveable out of the engaged position by application of a force acting to move the shoe with respect to the housing sufficient to overcome cooperation between the first and second detent features in the engaged position.
