An assembly capable of use in removing material from both ends of an elongated workpiece, such as a bar incorporates two similar pieces of apparatus of a known kind. Each apparatus has a cutter mounted at one end of a flexible drive and rotatable by a motor about its own axis to effect removal of the material; the cutter is supported in a universal mounting enabling the cutter to swing in a closed path about the axis of the cutter. The cutter is biased inwards towards the axis. The invention provides positioning means for moving the cutters aside into loading positions so that a finished workpiece can be removed laterally and a new one introduced laterally. The positioning means on each apparatus includes means for shifting the motor towards the universal mounting so as to cause the flexible drive to bow more markedly and move the cutter further from the axis, and a deflector for engaging the cutter-end of the flexible drive and moving it to its loading position. Restraining means restrains the bodily rotational movement of the flexible drive to steady the orbiting travel of the cutter.
