Abstract:
1. A circular saw comprising: a housing; a guard coupled to the housing; a circular saw blade associated with the housing and laterally positioned within the guard, the circular saw blade being rotatable about a rotational axis; a handle with a generally V-shaped portion coupled to the housing, the generally V-shaped portion being disposed generally transverse to the rotational axis and having a first end, a second end that is positioned rearward of the first end, an apex, which is disposed above the housing between the first and second ends; a battery pack fixedly but releasably engaged to the housing; a pair of grooves formed on one of the battery pack and the housing; a pair of rails formed on the other one of the battery pack and the housing, the rails being configured to cooperate with the grooves to align the battery pack to the housing; a shoe; and an adjustment mechanism having a first bracket, a depth-of-cut member and a clamp, the first bracket being fixedly coupled to the shoe, the depth-of-cut member being pivotally coupled to the first bracket, the clamp including a first threaded member and a second threaded member, the first threaded member being movably coupled to the depth-of-cut member and extending through the housing, the second threaded member being threadably engaged to the first threaded member and being configured to translate the first threaded member to selectively secure the depth-of-cut member to the housing, the first threaded member being disposed between the rotational axis and an aft end of the battery pack when the battery rack is fixedly but releasably engaged to the housing, the second threaded member being disposed on a side of the housing opposite the circular saw blade; wherein the battery pack includes a plurality of pack terminals and a battery, the pack terminals being disposed between the rails or grooves formed on the battery pack, wherein the pack terminals are associated with a top side of the battery pack and wherein at least a majority of the battery being disposed beneath the pack terminals and the rails or grooves formed on the battery pack; wherein a center of gravity of the circular saw including the battery pack is located in-line with a center of the generally V-shaped portion; wherein a trigger is mounted in an apex of the generally V-shaped portion; and wherein the center of gravity is disposed in-line with the trigger in a direction that is perpendicular to both the rotational axis and a direction in which the battery pack is releasably engaged to the housing.
