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 and demand of a jobsite or around the house projects. This 40-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, meaning the bit holders can be removed or rearranged to the user's liking. This allows for complete customization of RYOBI accessory kits.
