Abstract

A hand circular saw comprises a swinging protective hood, a housing which carries a saw shaft axis and a saw blade held rotatable about the saw blade axis, a base plate, the housing being arranged independently turnably relative to the base plate around two further axes extending substantially perpendicular to one another, a first of the further axes being parallel to the saw shaft axis for guiding a turning movement for adjusting a cutting depth and is adjustable on a cutting depth guiding bracket with a scale, while a second of the further axes extends both parallel to the base plate and also parallel to the saw blade for guiding a turning movement for adjusting a miter angle, the cutting depth guiding bracket having an angle-profile shaped cross-section and having at least one leg which is formed as a sliding guide supporting the housing in each cutting depth position.
