I bought a Milwaukee. It is bad to the bone. Highest torque rating of any battery impact on the market.
The half inch Milwaukee I had wouldn’t do half what my dewalt will do. But it may been a bad one or the “cheaper model” it came in a 5 piece set.
The 1/2” deWalt I have will out perform my pneumatic Ingersoll-ran thunder gun. But it’s also 20 years old, so it may be wore out. 😁😁
