Jet Edge Inc. (St. Michael, Minn.) has introduced a new pneumatic self-feeding drill for its precision waterjet cutting systems. The drill is available in stationary or laterally adjustable models. The air drill gives waterjet operators the opportunity to expand their cutting capabilities and take in new types of work by enabling them to quickly pierce sensitive materials prior to cutting them with a waterjet. It also can be used for reaming holes of a specified diameter. The drill works with any manufacturer’s waterjet system and features a hydraulic feed control unit, a feed-stroke adjustment, an exhaust collector and a PLC interface manifold. All controls are internal; there are no limit switches. The drill has a free running speed of 3,300 rpm and can be set for 0.3125- inch to 3-inch (7.9-mm to 76.2-mm) stroke lengths; it comes with a 0.25-inch/6.35-mm stainless steel drill chuck.
