Hitachi's new SuperDrive collated screw system has been improved for the professional subfloor, decking and dry-wall installer. The 19-inch extension handle lets the user install screws in a standing position to dramatically reduce fatigue. This system can drive screws ranging from 3/4 to 3 inches without any attachments. Depth control is achieved by the surelock fine adjustment, and bit life is deeply enhanced with the patented LOX drive system. This system has 12 points of contact between the bit and the screw, so the heads do not strip out. This tool runs at 2,600 rpm and comes complete with a case, LOX bit, Phillips bit for dry-wall screws, no-mar tip and sub-floor tip.
