The TI 15 impact drill and screwdriver is three tools rolled into one – an impact screw driver, screw driller and offset screwdriver. When it comes to assembly tasks which involve not just a lot, but a whole lot of screws and not just large ones, but really large ones, the TI 15 IMPACT with its EC-TEC engine proves a real powerhouse. Its special drill chuck with an integrated strike shut-off system makes it into a conventional screw driller with infinitely adjustable rotation speed, up to 2.600 rpm, while the fast fix interface and the offset attachment transform it into a real offset screwdriver.
