About This Product

The MILWAUKEE M18 FUEL ½" High Torque Impact Wrench w/ Pin Detent delivers up to 900 ft-lbs of fastening torque, greater access in tight spaces, and greater durability. The POWERSTATE Brushless Motor delivers up to 900 ft-lbs of Fastening Torque and 1,100 ft-lbs of Nut-Busting Torque, providing users with greater power for the most demanding applications. At 7.3" in length, the compact size gives users greater access in tight spaces. The robust design allows users to tackle the most demanding applications on the jobsite all while prolonging tool performance. The patented battery isolation system ensures a secure battery connection and controls vibration transmitted to the pack. Tri-LEDs surround the anvil to deliver brighter light with fewer shadows. The integrated lanyard loop allows users to easily transfer and store the tool. 4-Mode DRIVE CONTROL offers greater precision with a range of pre-set RPM and IPM levels, selectable from a single button on the tool. By selecting Mode 4, AUTO SHUT-OFF control applies no more than 50 ft-lbs of torque for hand-tight fastening applications to prevent overtightening. Mode 4 also features Bolt Removal Control that delivers users full torque output, then decreases RPMs once the bolt is loosened to prevent fastener drops. The ½" Pin Detent anvil design maximizes socket retention.

      This is one of the best tools that I have. I am disabled with only one arm. So this makes it so that I can do just about anything with my one hand. It is able to break bolts loose that I could not even get with my pneumatic gun. I was so impressed that I now own the half in, 3/8 in and the ratchet. Thank you Milwaukee!

      1/2" Impact
      Been wanting a 1/2" impact wrench for some time. This unit did not disappoint. Wondering why I waited so long. Easy to use and powerful. 4 settings for nice control & job flexibility.

        A bit of a heavy beast, but it gets the work done.
        I restore vintage railway equipment as a hobby, which means taking apart large bolts that haven't been removed since the day they were installed (50+ years). I clean up exposed threads to not promote damage to bolts that might want to shear after all that time/stress/rust, and this has yet to fail me. I particularly like that is more compact than the ¾" version, which is a real benefit in this application. A lot of the bolts were originally put in with 3' long wrenches for torque, and no thought was given to clearance for any larger tool.
