The Circle Wiz Cutting Attachment is a must for anyone who cuts small to medium holes in plate or pipe. It is especially handy for cutting out the holes for matching saddle cuts, weldolets and threadolets. Made of finished high quality steel. The universal bushing will adapt to any size or make of conventional cutting torch. Will cut holes from 5/8” to 8” in diameter (recommend Chariot Cutting Guide P/N 24219 for larger holes). Simply slide the center pin along the hex arm to attain the proper radius of hole desired. Place the sharpened point in your center mark and you are ready to cut.
