Small and mighty.
I bought this unit after my awesome experience with the dewalt 1/2 mid torque impact. I decided the snap on electric tooling was getting replaced. This 3/8” impact was much more compact which made me skeptical at first. Upon first use I knew this was a wise purchase. It put my 3/8 electric snap on one to shame. The tool is so much smaller and has way more power. I use this tool daily as a heavy duty mechanic and advise anyone on the fence to dive right in. The only downside I had was I had to get used to so much power at my finger tips. What I used to have to hammer tight for an extended period with the snap on impact results in overtightened broken bolts with this mighty guy. Which in turn lead me to find that the adjustable torque output button comes in very handy, it reduces the power output of the tool when you want a little fineness. I am very happy with this unit!
Compact with an outstanding breakaway torque!!
[This review was collected as part of a promotion.] While this 3/8 impact looks tiny, especially, compared to either earlier models or the 1/2” impact it sure does pack a punch. With 450ft-lb of breakaways and 300ft-lb of fastening what is not to like.
Verified Purchase
Great Impact
Very nice impact for its size, plenty of torque for the job that I use it for.
