Cutting apparatus for obliquely cutting elongate workpieces of substantial dimensions such as girders comprises a frame which supports a circular saw for rotation about a horizontal axis. Opposed to the saw is a workpiece locating and clamping device having two sets of clamping jaws which are spaced apart by a distance just sufficient to enable the saw to pass therebetween. The clamping device and the saw are pivotal about vertical axes and means are provided for coordinating this pivotal movement so that the inclination of the saw required for producing a particular angle of cut coincides with the inclination of the gap between the two sets of jaws.
