RYOBI Impact Rated Driving Bits are built to withstand the tough demand that comes with the use of an impact driver. The 2 in. bits feature a Torsion Zone that is engineered to absorb the high torque the bit takes on in many driving applications. This 30-piece kit offers a variety of nut drivers, phillips bits and bit holder that can all be used in a standard drill or an impact driver. The included case is compact and modular, meaning the bit holders can be removed or rearranged. This allows for complete customization of accessory kits.
