A work supporting plate for a machine tool is pivotally mounted between two normally fixed base arms and two swinging arms, the plate and arms being connected by a common pivot. A segment on each swinging arm has a row of uniformly spaced bores in an arc about the pivot axis for coarse adjustment of the angular plate portion in integral multiples of 1 DEG , and a threaded abutment on each swinging arm permits the swinging arms with the plate to be finely adjusted relative to the base arms.
