The STANLEY ID07 Impact/Drill is a versatile hydraulic underwater tool that combines an impact wrench and wood drill in one unit. The ½" square drive impact wrench provides up to 500 ft-lbs of torque, allowing you to tighten and loosen nuts, bolts, and drive lag screws. With the 05079 adapter and wood boring bits, the ID07 can drill up to 11/16" diameter holes in timbers without generating reactive torque, ensuring safety for divers. It also features a trigger guard and a hi-visibility yellow finish for added safety and easy identification.
