We’ve all used ½-inch drive impact wrenches over the years to remove wheels and loosen stubborn large fasteners from driveline components and suspension bits. Be it air or electric powered; these big brutes have been mainstays in shops and garages for decades. Only recently have battery operated impact wrenches have had the guts and battery life to really be considered by most. Probably the biggest change of recent memory is brushless motor technology (no more carbon brushes to wear out) and new battery technology like Lithium-Ion and other chemistry types that make batteries more efficient, last longer, and not have a charging “memory” like the old Nickel-Cadmium batteries (Ni-Cad).

Rockwell Tools has just launched a new impact wrench in its line of 20V MaxLithium line of tools. The 3-speed impact wrench (PN RK2855K2) features a brushless motor in a compact and light housing. Don’t let its small size fool you though; this impact wrench has some muscle! The brushless motor technology means up to 50 percent more run time over older brushed motor tools. Motor efficiency is also improved with computer-controlled power distribution, which reduces heat and wear. The brushless motor itself features a 10-year warranty and with no more carbon brushes to wear the motor is maintenance free.

“One major characteristic that sets Rockwell tools apart is our motor technology,” said Jeanne White, Rockwell’s Senior Product Manager. “It’s an area in which our engineers excel, and this new brushless impact wrench is no exception.”

The 20V MaxLithium impact wrench features a compact form with a short nosepiece, allowing the impact wrench to fit in smaller spaces than traditional ½-inch drive impact wrenches. The rubber over mold makes for a comfortable fit in your hand too.

Due to its compact size the Rockwell 20V MaxLithium impact wrench is perfect for on-site emergency tire changes. At just 3.3 pounds you can simply throw it in your tool bag for road trips. The on-board LED work light means that you’ll easily see your work area even on the darkest roads. You’ll get that spare switched out safely and quickly and be back on the road without barely breaking a sweat versus trying to use some rusty old four-way wrench or the factory lug wrench in your trunk. The 3-speed gearbox means you’ll always have the right power output for the job. The impact wrench features a digital readout of 73/132/220 ft/lbs. of torque. The tool has a no-load speed of 1,300/2,100/2,900 rpm and its impact rate is 0-1,600/2,900/3,300 impacts per minute (ipm).

Included in the kit are two 20V MaxLithium 2.0 Ah batteries, a one-hour charger, belt-clip, and a carry/storage bag. The impact wrench features a 3-year warranty (and as mentioned previously, a 10-year warranty on the motor itself). Rockwell’s Batteries for Life program is included upon registration of your impact wrench, which provides free replacement batteries to the original purchaser for the life of the tool. The Rockwell 20V MaxLithium impact wrench will be available in September 2015 at fine tool retailers, including Menards, Amazon, and at Rockwell Tools’ website for suggested retail of $259.
