The invention relates to a cutting tool especially useful for cut-off, threading and grooving operations. The tool includes a massive block-like body with serrations along one or both sides. An adjustable plate with interengaging complemental serrations is mounted on the side of the body and retained by bolts which transfix the plate and anchor in the body. The plate has a top recess to receive short cutting elements backed up by a similarly shaped rod. A broached out-of-round hole is cut into the body parallel to the serrated wall to receive at one end a threaded anchor nut and at the other end a shank of a clamp bar.
