    摘要: A motor driven hand circular saw has a base plate arranged to be positioned over a workpiece, and a saw blade which is displaceable parallel and tiltably about a turning axle relative to the base plate for performing inclined or bevel cuts so that by tilting of the saw blade relative to the base plate about the axle, the saw blade and the axle are displaced parallel to the base plate with a stroke which is proportional to a respective tilting angle transversely to a direction downstream of a cutting point and counteracts a natural displacement of a saw engaging line of the saw blade on the workpiece.
