With the 7-piece Phantom 69.210 annular cutter set, you drill clean and accurate large-diameter holes in metal, beams, and profiles without time-consuming pre-drilling. Because the hss-ex cutters remove material only along the perimeter of the hole, you drill much more efficiently with reduced machine strain. The set includes six popular diameters from 12 to 22 mm alongside an ejector pin that centers the cut and automatically ejects the metal slug. Thanks to the universal 19 mm Weldon shank with quick-change compatibility, you can mount every cutter securely onto your magnetic drill press or workshop drill for reliable, burr-free results.
