Abstract:
1. A reciprocating saw comprising: a housing including a handle housing portion, a motor housing portion, and a gear case housing portion, the handle housing portion having a longitudinal axis that defines a first axis of the reciprocating saw, the housing being formed from a first housing portion and a second housing portion, each of said first housing portion including a boss, the boss of the first housing portion and said second housing portion aligned with the boss of the second housing portion; a motor supported by the motor housing portion, the motor including an output shaft having a longitudinal axis that defines a second axis of the reciprocating saw; a switch positioned on the handle housing portion, the switch configured to power the reciprocating saw; a pinion gear coupled to the output shaft of the motor for rotation with the output shaft; a driven gear engaged with the pinion gear such that the driven gear rotates in response to rotation of the pinion gear; a spindle coupled to the driven gear such that rotation of the driven gear by the pinion gear reciprocates the spindle along a longitudinal axis of the spindle that defines a third axis of the reciprocating saw; a blade clamp coupled to the spindle such that the blade clamp reciprocates with the spindle, the blade clamp configured to couple a saw blade to the spindle; a gear case supported by the gear case housing portion, the gear case substantially enclosing the pinion gear and the driven gear, the gear case coupled to the housing and being electrically isolated from the housing, the gear case including a tab with an aperture, the aperture of the tab receiving at least one of the bosses of the first housing portion and the second housing portion; and a fastener extending through the bosses to couple the gear case to the housing, wherein the bosses electrically isolate the gear case from the fastener, wherein the first axis, the second axis, and the third axis are oblique with respect to each of the other axes, wherein the second axis and the third axis define a first angle, and wherein the first angle is in a range of 110 degrees to 130 degrees.
