An angle vise includes a body with a curvilinear guide rail having a predetermined number of graduation holes on its outer surface, the holes being arranged in a manner such that a line connecting the centers of the graduation holes is a curve with a same center of curvature as the guide rail and located in equal intervals, a base with a curvilinear guide way having a predetermined number of selector holes located in equal intervals therealong in a manner that a line connecting the centers of these selector holes is coincident with the line connecting the centers of graduation holes. The interval between any two consecutive selector holes is smaller than the interval between any two consecutive graduation holes so that more setting of inclination may be achieved by aligning a graduation hole. Alignment is achieved through the holes with a selector hole by inserting a pin.
