Milwaukee Electric 2967-20 M18 Fuel 1/2 High Torque Impact Wrench with Friction Ring
Milwaukee's 2967-20 M18 Fuel 1/2 high torque impact wrench with friction ring, a pro-grade bare tool for heavy automotive work.
DEWALT 20V MAX Cordless Impact Wrench, 1/2 Impact Gun, 4-Speed High Torque with Hog Ring Anvil and LED Light, Brushless Motor, Tool Only (DCF900B)
DEWALT's DCF900B 20V MAX brushless 1/2 impact wrench with 4-speed control, hog ring anvil and LED light, tool only.
An impact wrench delivers sudden, high-torque bursts that break loose rusted lug nuts and seized bolts a regular ratchet cannot budge. It is a favorite for anyone doing wheel changes, brake jobs, or suspension work, and it saves both time and knuckles. You will choose between cordless models, which are convenient and portable, and air-powered ones that need a compressor but run lighter in the hand. Focus on breakaway torque for loosening and fastening torque for driving, plus a 1/2-inch drive for most automotive work. Multiple power settings help avoid stripping threads, and a hog-ring or friction-ring anvil affects how easily sockets swap on and off.
