The Ryobi R18ID2-0 is a high-powered Impact Driver designed to quickly fasten or loosen long screws or large bolts. Unlike a Combi Drill, an Impact Driver is capable of delivering very high amounts of torque whilst causing very little twist or reactionary feedback through its handle. This makes the R18ID2-0 ideal for decking, fencing and roofing, where fastening larger fixings, coach bolts and long screws are essential.
