The Hilti SIW 4R-22 and Hilti SID 4R-22 right angle impact wrenches were developed for hard-to-reach areas such as metal bolts on handrails, shelves and machines. The longer handle and the integrated battery interface provide greater reach in confined spaces. The impact wrenches have a robust 3/8" anvil with friction ring for quick socket changes or a 1/4" hexagonal quick-change chuck for easy drill bit replacement.
Statement by the Jury
The compact, battery-operated Hilti SIW 4R-22 and SID 4R-22 right angle impact wrenches inspire confidence with their detailed, carefully thought-through design for professional use.
