AutomationDirect has presented the RUKO family of cutting tools, which now includes a line of hole saws and accessories. The new bi-metal saws, in sizes ranging from 9/16 inches (14 mm) to 8¼ inches (210 mm), feature up to 1½-inch cutting depth and are available in two models.

The high-speed steel saws easily cut materials such as unalloyed steel, non-ferrous and light metals, plastics, plasterboard and light building boards, fiberboard, plywood and wood. Cobalt 8 saws, with fine cutting teeth, work well with metals such as alloyed and non-alloyed steels, high chromium alloyed steels, such as stainless steel, steels resistant to rust and acids, non-ferrous and light metals. Constructed with an alloyed steel 6135 jacket, the saws feature high rotational precision, positive chipping and cutting angles and good chip removal. Slots in the jacket side aid in removal of cutouts. The hole saw and shank are in two parts, so hole saws of different diameters can be exchanged and fitted more quickly.
