Milwaukee 2864-20 Impact Wrench Review: Unbiased Verdict

I was three days into a suspension rebuild on a 3/4-ton truck when I hit the bolt that stops every backyard mechanic cold — the lower control arm bolt, torqued to 250 ft-lbs at the factory eight winters ago, crusted in rust and undercoating. My pneumatic impact gun wheezed. A breaker bar with a six-foot pipe just bowed the frame. That is the moment I started wondering whether a cordless impact wrench with serious nut-busting torque could actually replace the air tools I had been using for fifteen years. I ordered the Milwaukee 2864-20 impact wrench review unit expecting to be impressed. What I did not expect was how thoroughly it would change what I keep in my tool box. This is not a sponsored verdict. It is what I found after putting the thing through every job I could throw at it.
