RYOBI Impact Rated Driving Bits are built to withstand the tough demand that comes with the use of an impact driver. With a Torsion Zone that is engineered to absorb the high torque and demand of a jobsite or around the house projects, this is the only driving kit that is needed to get the job done. This 70-piece piece kit offers a variety of the most commonly used 1 in. and 2 in. bits, along with specialty socket adaptors, nut drivers and a magnetic screw guide. The included case is compact and modular so that the user can remove or rearrange bit holders to their liking. This allows for complete customization of RYOBI accessory kits.
