    Great air tool for a modest sized compressor

    This tool worked great with a 12 gallon 6 cfm at 90 PSI air compressor. Easily removed lug nuts and rusted VW axle nuts. Struggled with an old front wheel bearing, but still worked. Seems very well made and hopefully will last me for years.

    The Price And a 3 Year WARRANTY Is The Best For The Price, I Look At Price and Warranty Be four I Buy. I Look At NAPA & Advance Auto if You Want To Pay a Lot For One, A One Year.

    love it!

    I am very pleased with the price & how well this impact wrench works! Can't complain

    Great product

    Great product, this impact wrench ( Bostitch ) works very well and has great power. It makes the removing lawn mower blades faster and easier. Bob

    Best buy for the money

    I bought this impact to work on my personal vehicles at home but, out of curiosity, I took this impact wrench to my work before heading home with it to see how well it would perform. I work for a trucking company that has its own shop. I gave this impact to one of our mechanics, who in turn removed a lug nut from a big truck. This impact spun the lug nut off in about a second or 2 with no problem. He then put the impact on its highest forward setting and put the lug nut back on. After the lug nut was as tight as he could get it with the impact he checked the torque with a torque wrench made for torquing big truck lug nuts. The torque wrench is set at 475 foot pounds of torque and only put about another 1/8 of a turn on the lug nut before clicking.... That's some pretty impressive power for $80 and more than enough power for what most people would ever need working on their own personal vehicles. The warranty on this impact (3 years) is great as well. Most other impacts, many of which cost 3 to 4 tines the price, only come with a 1 year warranty. The cfm rating is also very low for an impact in the sub $100 range. 3.9 cfm is almost unheard of in this price range. Most of the brands I have looked at below $100 were at 5.0 cfm or more. This means that you don't have to have a big expensive air compressor for this tool to work, although you do still need one that puts out at least 3.9 cfm @ 90 psi to get the full power from the tool. You will also need a 3/8 air line at the minimum. The 1/4 pig tail lines that come with some of the cheaper air compressors will not provide the tool with enough air flow for it function properly. One downside, if you want to call it that, is that this impact is pretty heavy compared to some of the more pricier brands, weighing in at just under 6 pounds. This isn't a problem for me but I thought I would mention it. In summary, if you are looking for a solid, powerful, impact under $100, you won't be disappointed with the Bosch. Just make sure you have a compressor that put out enough cfm and a good air line.

    Very Powerful

    I am not a huge handy person but I know when a power tool is good by its...Power! When I first hit the button, I was actually a little scared at first. This tool is extremely versatile for projects as big as fixing up your car to little things like filling air in your tires. Highly recommended!

    New air gun

    This air gun is the best I've had. I didn't know when I bought it that it is variable can vary the impact by the amount of pressure you put on the trigger, very useful! When needed it has amazing torque, both in forward and reverse. And it uses less air than my last one.

    Very good impact for the price.

    I like to have one impact wrench for my cars repairs need. This wrench is powerful, good size, solid and easy to use. And for the prize is even better.

    Works with Pancake Comp

    I have 6 gallon 2.6 cfm compressor @ 90 PSI, and it worked fine. Compressor turns on after getting one wheel of lugs off, but no biggie to me. Was tough at first getting brake rotor bracket off, but turned up PSI to 110 like someone suggested, and came right off. For the do it yourself mechanic that doesn't use it often and is patience when compressor kicks on, I think it is fine.

    Great Value Impact Wrench!

    The only reason why I didn't give it 5 stars is because the ergonomics could have been design better, but it gets the job done.

    1. I've found that it depends on the amount of pressure on the trigger..but when fully depressed it has the full amount of torque for as long as you need it. I believe this is a very good air gun especially for the price.
