Machine tool for cutting work

A machine tool, such as a manual circular saw, comprising a plate (2), a disk-shaped cutting tool (1, 17) and a working unit mounting said cutting tool and including a mechanism (3) for driving said cutting tool (1, 17) said driving mechanism (3) having a length extending transversely of said cutting tool (1, 17), said working unit is pivotally displaceable relative to and fixable to said stop plate (2), said stop plate (2) having a first surface mounting said working unit and an oppositely facing second surface, said disk-shaped cutting tool (1, 17) having a first side facing said driving mechanism (3), said first side of said cutting tool (1, 17) and said second surface of said stop plate (2) being perpendicular to one another in a first position of said cutting tool (1, 17), said first side of said cutting tool intersects along an intersection line (20) with said second surface of said plate, wherein during pivoting of said working unit said cutting tool (1, 17) having a center (16) moving on a geometric path (5) within a cylinder (18) having a center axis extending along the intersection line (20) and a radius (R) corresponding to the distance between the intersection line (20) and the center (16) of the cutting tool.
