This attachment can turn an ordinary screwdriver into a band screwdriver. Anyone who works with the installation of structures, finishing or roofing will appreciate this tuning. Such an attachment is simply indispensable when you need to screw thousands of screws, because the process of working with a band feed is accelerated several times. The principle of operation is very simple - when screwing a screw, the front part is pressed, the mechanism grabs and, when released, moves the tape one cell up. There is a limitation on the size of the screw - more than 35 mm will not fit.
