The DEWALT DC855KA 9.6-volt Cordless Impact Driver is a super-compact, ultra-lightweight tool that produces a surprising amount of raw power. This pro-duty, -1/4 -inch, hex-shank tool weighs just 3.3 lbs., and is only 5-3/4 -inch long, but it can take on demanding fastening jobs, such as tightening large bolts and nuts, and driving long lag screws and Tapcons. It’s powered by DEWALT’s exclusive 9.6-volt XRP extended-run battery, which delivers both rotation (0-2,400 RPM) and concussive blows (0-2,700 BPM) directly to the fastener. The result is an impressive 960 -inch-lbs. of turning force. Other features include: frameless motor with replaceable brushes; compact size for use in tight spaces; textured, anti-slip grip; durable magnesium gear case and all-metal transmission; and a unique impact mechanism that reduces kickback and directs all that torque to the fastener. The DC855KA -1/4 -inch Cordless Impact Wrench comes with two 9.6-volt XRP extended-run batteries, one-hour charger and a storage case. It’s backed by DEWALT’s three-year limited warranty, 90-day money-back guarantee, and one-year free service contract.
