The Steelman PRO Impact Grade Bit Driver Sets are available in the 25-pc set and the 50-pc set. The 25-pc set (No. 78632) includes Philips, Torx and hex ball (standard and metric) bits. Also included are three quick-release bit holders of different lengths and three socket drive bits for 1/4" and 3/8" drive sockets. The 50-pc set (No. 78633) includes everything that the 25-pc set has, plus a hex bit set, nut drivers and a flat-head bit. Also included in the 50-pc set are expanded sizes for the hex ball, Torx and socket drive bits. All bits exceed ANSI torque and lifecycle specifications, are made of industrial-grade steel and heat treated to impact-grade standards. Each bit’s size is laser etched into the shaft. The metric and standard bits are different lengths to allow for quick visual identification.
