A circular saw includes a base plate, a saw blade assembly pivotably mounted to the base plate, and a bevel adjustment assembly operable to adjust the bevel angle of the saw blade assembly by rotation of an axle supported on the base plate. A release mechanism includes two torsion springs each having a coil portion wound around the axle, an anchor leg held in a substantially fixed position relative to the axle and a release leg arranged to move relative to the axle. A manually operable release element is configured to substantially simultaneously move the release leg of each of the torsion springs in a direction to unwind the coil portion of each spring from about the axle.

A power tool includes a work-piece support surface, a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface, a latch pin movable between a first position whereat the latch pin is engaged with the swing arm assembly and a second position whereat the latch is not engaged with the swing arm assembly, a pressure operated actuator configured to force the latch pin from the first position to the second position and to force the swing arm assembly away from the first swing arm position and toward the second swing arm position, and a control system configured to actuate the actuator.

A preferred embodiment of the invention comprises a tool chuck for a power hand tool of the type which has a generally cylindrical elongated housing with a motor contained within the housing or case and the motor having an output shaft that extends from the nose end of the hand tool, and which has one or more light producing devices located at its nose end for illuminating the work area during operation. The preferred embodiment of the tool chuck has an annular cylindrical light transmitting portion on the outside of the chuck body portion for transmitting light toward a tool bit held by the tool chuck. The preferred embodiment may have an inwardly oriented front end surface to direct the transmitted light toward the axis of the tool bit and may have an outer layer of resilient material to facilitate easy gripping of the tool chuck to tighten or loosen a tool bit.

A battery operated power tool having a power tool housing, a battery pack and a battery latch mechanism. The power tool housing has a recess and a latching surface formed into the outer surface of the housing. The battery pack holds battery cells to power the tool. The battery latch mechanism removably attaches the battery pack to the power tool housing and includes a latching member and a spring to bias the latching member between an engaged position where the latching member is connected to the power tool housing and a release position when the latching member is disconnected from the power tool housing. The latching member includes an inner and an outer side with a latch flange on the inner side at one end. Towards an opposing end, the latching member includes a pushing surface on the outer side.
