1. An auxiliary handle for use with a power tool having a housing that includes a first notch and a second notch, the auxiliary handle comprising:
a shaft defining a shaft axis;
a first clamp coupled to the shaft and having a first body portion extending along the shaft axis, a first leg portion extending from the first body portion in a direction transverse to the first body portion, and a first protrusion extending from the first leg portion in a direction transverse to the first leg portion, the first protrusion configured to engage the first notch;
a second clamp arranged on the shaft and having a second body portion extending along the shaft axis, a second leg portion extending from the second body portion in a direction transverse to the second body portion, and a second protrusion extending from the second leg portion in a direction transverse to the second leg portion, the second protrusion configured to engage the second notch, wherein 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, such that the auxiliary handle is coupled to the housing of the power tool, and a second position, in which the second protrusion is disengaged from the second notch, such that the auxiliary handle is removable from the housing; and
a grip coupled to the shaft,
wherein when the grip is rotated relative to the second clamp, the second clamp is moved from the second position toward the first position, and
wherein a first recess is defined between the first body portion and the first protrusion, and wherein a first nose portion adjacent the first notch of the housing is configured to be received in the first recess when the first protrusion engages the first notch, such that the first protrusion is inhibited from disengaging from the first notch.
