A screwdriver bit is a tool for driving screws and one that can be fitted to most drilling power tools. All screws have a head with a contour such that an appropriate screwdriver tip can be engaged in it in such a way that the application of sufficient torque to the screwdriver will cause the screw to rotate.

IRWIN 9-in-1 Multi-Tool takes versatility and convenience to a new level. This professional-grade tool features six (6) bits and three (3) nut drivers, the most common sizes-all conveniently stored inside the tool in a unique stacking configuration, so the right fastening tool will always be at your fingertips. The 9-in-1 Multi-Tool also features IRWIN ergonomic ProTouch Grip, providing comfort and slip resistance for maximum torque.
