Quality results require quality tools. Quick, professional results are easy to achieve with the wolfcraft 4-piece wood countersink screw setter set. wolfcraft’s unique design lets you work efficiently, reducing three steps into one: drill, countersink and counterbore in one pass. German-made set includes 4 wood countersinks with drill bits and one hex key for depth stop adjustments. The tapered drill bits are made from premium, German High Speed Steel. They have wide, parabolic flutes that drill fast and clean pilot holes and the tapered shape ensures a tight fit for screws. The 45-degree countersinks have built-in depth stops! Loosen the set screw with the included hex key and adjust the depth of the pilot hole. The built-in counterbores allow you to bore for 1/4, 5/16, 3/8 & 1/2-inch diameter plugs, buttons and dowel pins. Made by wolfcraft in Germany. wolfcraft – Master Quality & Innovation Since 1949
