Abstract
A circular saw, in particular hand circular saw, is disclosed. The circular saw has a workpiece support surface, a saw blade and a protective cover, which covers the saw blade in a region above a workpiece to be processed. The protective cover has such a geometry and position with respect to the saw blade that a straight line, which originates from the first deflection of a tangent applied at the intersection of the saw blade circumference with the workpiece support surface from the protective cover encloses an angle of up to 30°, in particular up to 20°, with a line perpendicular to the workpiece support surface.
