Professional Tool Reviews for Pros


Rockwell RK2855K2 20V Max Brushless Impact Wrench

Rockwell 20V Max Brushless 1/2" Impact Wrench

Rockwell has announced the newest addition to their cordless line. The Rockwell RK2855K2 20V Max Brushless 1/2″ Impact Wrench is expected to have an extended runtime and lifespan thanks to its brushless motor. It features a 3-speed digital gearbox with torque levels of 1150, 1770, and 2300 inch pounds.

Rockwell RK2855K2 20V Max Brushless 1/2″ Impact Wrench Features

For most impact wrench users, having multiple speeds and operating torque settings is beneficial. Certainly the most torque is required for those metal to metal fastening applications. 2300 inch pounds (192 foot pounds) doesn’t compare to the high-torque models on the market, but it’s certainly enough to handle the majority of DIY needs. Taken outside the auto shop, impact wrenches serve as socket wrench replacement. You don’t necessarily need all the available torque and that’s where the multiple gear settings really come in handy.

“Having a tool like this at your disposal is empowering. It handles mechanics’ jobs, but it also performs building and assembly tasks with no problem, such as driving 3 inch lag screws when building decks.”

– Jeanne White, Rockwell’s Senior Product Manager

The Rockwell RK2855K2 20V Max Brushless 1/2″ Impact Wrench also features computer-controlled power distribution. This electronic communication improves efficiency and durability by reducing heat, friction, and wear. An on-board battery fuel gauge helps track charge status. For applications in low light areas, the impact wrench has LED work light.


We’ve taken a look at Rockwell’s 16V Max drill driver and impact driver previously. It’s nice to see that they’ve moved from the 16V Max (AKA the old 14.4V platform) up to 20V Max. Check out our article on 20V Max vs. 18V platforms to see the significance. For fans of the brand, the Rockwell 20V Max Brushless 1/2″ Impact Wrench will be a nice addition to the line.

I got this impact (RK2855K2) for fathers day this year. I was really excited that it was gotten on sale ($90). Love that its light weight and comfortable. My old one just took a dump and figured this would be a great replacement for it. Rockwell is a high quality company but it lacks the power for my needs in my automotive DIY. My lungs are torqued to 98 ft lbs but even on max torque it just could budge them. It still works great for many other applications but I was a little disappointed. Still a great buy for… Read more »
