If you want to use the BOSCH Rotary Hammer to insert and remove screws, you need screwdriver bits and a universal holder with SDS-plus shank to insert the bits. There are four bit shapes that match the different screw heads: slotted, hexagon socket, cross-head and Torx. Make sure that you use only bits that exactly match the relevant screw head. Otherwise the screw head is quickly destroyed and you will require a lot of effort later to remove the screw and you will be unable to reuse it. You will find the appropriate bits for your BOSCH Rotary Hammer at specialist dealers or in DIY markets.
