The invention provides a hand-held circular saw comprising a base plate and a cutting unit pivotally mounted on the base plate. The cutting unit includes a saw blade, a motor driving the saw blade, and a fixed guard covering at least a part of the saw blade. A guide plate with an arc-shaped slot extends from the base plate. A connecting member or bracket has a first end that is mounted to the cutting unit and a body portion operably connected to the guide plate by a locking element, namely a bolt, and a lever. Once released, the lever allows for movement of the bracket and the blade with respect to the guide plate. A stopper is mounted on the guide plate and is movable between a first position and a second position. In the first position, at least a part of the stopper intercepts the arc-shaped slot and stops the bolt from moving further within the arc-shaped slot. In the second position, at least a part of the stopper does not contact the bolt whereby the bolt is free to move within the slot and the bracket is fully adjustable.
