Really good tool
The tool that I purchased from this site really aid me in my profession, being an auto mechanic sometimes you need power where the tool can't fit so I ordered some tools from here and now I can put power where I need it

A money making tool
I fix cars for living and having a 3/8 cordless impact wrench saves me a lot of time, i've owned several brands of impacts and this guy is the best so far , its light and powerful, i have been using it for two weeks every day and all day long, still has not charged or used second battery, love it, little bolts, big bolts, lug nuts it does it all. Great buy.

This is a serious workhorse!
I bought this impact initially to do repairs to production units on a make like production basis. Right out of the box it performed flawlessly. After a quick battery charge to get started, I ran a 10 hour shift on one fat pack battery. I even changed a flat tire on my car at lunch time, then changed all four wheels on my car after I got home from work and still had life in the battery. To save money, I opted for a reconditioned impact and so far I have no regrets. It looked and operated like a brand new tool. It fits nicely in the case and there is still room for one set each of deep and shallow sockets. After two weeks, I also bought an 18v Bosch drill to replace a tried and true but gracefully aging DeWalt so now I have two slim pack HC batteries to go with my fat packs. It's the best of both worlds, loads of power in a light weight package or the endurance of the fat pack if I need to use the tools non-stop for hours on end.
The best features: The power, the battery life, the belt clip when your hands are busy fitting or removing parts, the trigger control to safely start fasteners very slowly and carefully to ensure proper thread engagement before running them down. You don't get this kind of control with any air impact. Not that air tools don't have their place but I would never start fasteners on a production basis with an air impact because of the risk of cross threading and not knowing it before it's too late and the damage is done. With the cordless impact it is very easy to start fasteners at near zero torque with virtually no risk of damaging threads.
The more I use this tool, the more I like it. I have nothing bad to say about my DeWalt tools but they did not make a 3/8 square drive impact in the 20v lithium line when I was ready to buy so the win goes to Bosch on this one. My only regret is that my beloved 3/8 I.R. air impact just might find a place on the shelf with my old film cameras. Say it ain't so but the air line stays coiled up under the bench more than ever as the new "kid" takes over. Once you make the jump to cordless, it's hard to go back.

Germanic sturdiness and utility
Powerful tool for major projects including deck building, automotive applications. Extended use between battery charges. Battery charger is very straight-forward to use, unlike many others. I bought a chuck attachment, increasing quick versatility. One thing, this is a heavy tool and repeated horizontal use can be challenging.

Size does matter
My company assembles a lot of machinery and conveyors. The Bosch impact wrench is one of the few with 3/8" drives, all the others are 1/2" and too big for our application. Very handy and quick to use in tight places. My technicians love them so much I had to buy each one there own.

Great compact impact
I use the impact to install air conditioning and fire suppression systems , the small size and light weight are a definite plus and battery life is longer than I had expected . It's Bosch that should say a lot on it's own.

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 60 days.
