Abstract: A tile saw comprising a base, a table supported by the base and configured to support a workpiece, a guide rail upon which the table is supported and moveable along a longitudinal axis, a saw unit coupled to the base, and a roller assembly for supporting the table upon the guide rail. The roller assembly includes a first roller rotatably supported by the table and engaged with a first portion of the guide rail, and a second roller rotatably supported by the table and engaged with a second portion of the guide rail that is different than the first portion. The second roller is translatable relative to the table in a direction toward the guide rail. The roller assembly further includes a spring biasing the second roller toward the guide rail.

Abstract: An auxiliary handle is for use with a power tool having a housing that includes a first notch and a second notch. The auxiliary handle includes a shaft, a first clamp coupled to the shaft and having a first protrusion configured to engage the first notch, and a second clamp arranged on the shaft and having a second protrusion configured to engage the second notch. When the first protrusion of the first clamp engages the first notch, the second clamp is movable along the shaft between a first position, in which the second protrusion engages the second notch, and a second position, in which the second protrusion is disengaged from the second notch. The auxiliary handle also includes a grip coupled to the shaft. When the grip is rotated relative to the second clamp, the second clamp is moved from the second position toward the first position.

Abstract: A pneumatic fastener driver operable in a single sequential mode and a bump-fire mode, and includes a housing, a nosepiece, a trigger moveable between a default position and a depressed position, a contact arm movable relative to the nosepiece between an extended position and a retracted position, and a timeout mechanism operable in the bump-fire mode to inhibit the drive cycle from being initiated in response to inactivity of the contact arm over a preset time interval defined by unwinding of a mainspring that is initially wound in response to the trigger being actuated from the default position to the depressed position. The pneumatic fastener driver also includes a counting assembly having a female barrel pivotably coupled to a pivot shaft of the trigger and driven by the mainspring and a lockout linkage coupled to the female barrel that is capable of interfering with a portion of the trigger.

Abstract: In an angle-grinder with a rotating handle and a latch for fixing the handle in two different rotational positions, an interlock mechanism is provided for greater security against unwanted rotation of the handle when the tool is being used. The interlock mechanism is moved to a locking position by depressing the trigger to start the motor, and thus provides a safety lock backing up the latch, in case the latch is accidentally released during use. In its unlocking position the interlock mechanism may prevent actuation of the trigger when the handle is not properly aligned in one of its operating positions.

Abstract: An electric motor includes a stator operable to produce a magnetic field and defining an opening, and a rotor at least partially disposed within the opening. The rotor includes a shaft extending along a rotational axis, a first rotor magnetic core portion including a plurality of laminations stacked contiguously on the shaft, and a second rotor magnetic core portion coupled to the plurality of laminations. The first rotor magnetic core portion and the second rotor magnetic core portion cooperate to define the rotor magnetic core. A plurality of windings is coupled to the rotor magnetic core and an air flow path is formed as part of the second rotor magnetic core portion. The air flow path includes an axial portion that passes through the shaft axially along the rotational axis and a radial portion that extends radially outward through the second rotor magnetic core portion.
