Abstract

A power tool assembly includes a hand-held power tool, a dust collector removably coupled to the power tool, and first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.

First claim

What is claimed is:

1. A power tool assembly, comprising:
a hand-held power tool;
a dust collector removably coupled to the power tool, the dust collector including
a housing,
a telescoping suction pipe coupled to the housing,
an electric motor positioned in the housing,
a suction fan driven by the electric motor and operable to generate a vacuum in the suction pipe,
a dust container coupled to the housing and positioned upstream of the suction fan, and
at least one of
an extension stop adjustably coupled along the length of the suction pipe to limit an extent to which the suction pipe telescopes from the housing, or
a plunge depth stop adjustably coupled along the length of the suction pipe to limit an extent to which the suction pipe telescopes into the housing,

wherein the suction pipe includes a rail along which the extension stop or the plunge depth stop are movable, wherein the suction pipe includes a detent plate including spaced detents along a length of the detent plate that is coupled to the rail, wherein each of the extension stop and the plunge depth stop includes a detent member that is selectively engageable with one of the detents to lock the extension stop and the plunge depth stop to the detent plate, and wherein each of the extension stop and the plunge depth stop includes an actuator, and wherein the detent member in each of the extension stop and the plunge depth stop is biased toward an engaged position with the detent plate in a released position of the actuator; and

first and second power tool battery packs each of which is interchangeably coupled with the power tool and the dust collector for separately powering the power tool and the dust collector, respectively.

2. The power tool assembly of claim 1 , wherein the detent member in each of the extension stop and the plunge depth stop is moved toward a disengaged position from the detent plate in response to the actuator being moved to a depressed position, permitting the extension stop or the plunge depth stop to be repositioned along the rail.

3. The power tool assembly of claim 1 , wherein the housing includes an aperture in which the actuator of the extension stop is received.

4. The power tool assembly of claim 1 , wherein the housing includes a stop surface at least partially defining a notch within the housing, and wherein the plunge depth stop is engageable with the stop surface to limit an extent to which the suction pipe telescopes into the housing.

5. The power tool assembly of claim 1 , wherein the suction pipe is telescopically movable relative to the housing from an extended position to a retracted position in response to being depressed against a workpiece.
