From the Manufacturer
Powerful 6.4 AMP motor for heavy duty use. The W6VB3SD screwdriver runs at 2800 rpm and provides more than enough power to place 3-inch screws. The SuperDrive system uses a 20-inch extension bar to allow the user to install screws in a comfortable standing position. With a simple adjustment the extension bar can be removed for easy installation of drywall screws or metal to metal screw construction. The SuperDrive system can use screws sizing from 3/4-inch to 3 inches with diameters of #6 to #12. Included with the SuperDrive system is a pre-installed Lox bit, a heavy duty carrying bag, directions for both the W6V3 and SuperDrive, a case hardened steel drywall nosepiece and a Phillips head bit.
