Must have for industrial boiler/chiller work
Hey everyone. Recently bought this to use for boiler and chiller work. This has amazing power, amazing torque and can break loose bolts that have been torqued down 50 years ago.

Good job team red for making another amazing product!

I use this bad boy to take the wheels off my semi trucks and even when the tire guy over tightens them this beast just smacks them loose. Someone grabbed it decided to change his tire on a car with it and it broke off the stud like it was butter if you're looking for a strong weapon against tight fasteners grab one

Would buy again
Just bought 7 of them to upgrade from the mid-range torque impact fuel for five road crews and two supervisor trucks. I have used mine to break semi lugs loose. Great tools batteries last long time. Only problem we have they don't come with any decals, a hat or some sockets.

Absolutely the best impact on the market today!
I am a diesel mechanic in the oilfield. All my Milwakee tools get a beating, but none more than my 1/2 inch M18. I have removed trailer tires on a Frac pump with this tool. I have drowned this tool in acid, and she keeps going. I will never own another cordless tool. Thanks Milwake!!! For making a remarkable tool for everyone to use.

I use this product mainly in light automotive work. The wrench removes the tightest lug nuts with the simple push of the trigger. I have tried breaker bars and usually strain my self. It is also fantastic for removing the locking nuts on wheel hubs. No effort needed. Treat yourself to one of these tools and you will not regret the purchase.

This is one of the best tools made
No need for air tools with the M18 line up. I am very impressed with the quality and power of all of their tools. This impact tool is simply a beast. It pounds through any rust or tightened bolt. Batteries are pricey but outstanding power and work life.

New Vs. Reconditioned

What's the difference between New and Factory-Reconditioned?

Factory-Reconditioned products have been returned to the manufacturer and are restored to like-new operating condition; they go through a rigorous testing and inspection process. Plus, they offer a significant savings vs. new.
  • Reconditioned products may have minor cosmetic blemishes or scratches that do not affect item performance.
  • Reconditioned products may not come with all of the consumables the new version comes with (bits, sanding pads/papers, cases, etc.).
  • Both come with a manufacturer warranty and are covered by our Money Back Guarantee; New is 30 days, Reconditioned is 120 days.
