ABSTRACT:
A hand circular saw has a saw blade rotatable about a saw shaft axis, a housing which receives the saw shaft axis, a base plate which supports the housing and is movable with the latter, the housing being turnable relative to the base plate about two axes extending perpendicular to one another independently from one another and arrestable, the axis including a first axis which extends parallel to the saw shaft axis and operates for adjusting a cutting depth, and a second axis which extends both parallel to the base plate and to the saw blade and is used for adjustment of a miter angle, a coulisse having a circular arc-shaped guiding track and a coulisse block which determine a position of the second axis. The coulisse has a coulisse part which is fixedly connected with the base plate and has an upwardly curved ring portion which is also arranged on the base plate. The ring portion has a convex side which has the guiding track extending upwardly and has a center of curvature coinciding with the second axis used for adjustment of the miter angle.
