                      Fantastic impact. Great for taking tires off and fitting into tight places.
                      by
                      Impact operates great just wish I purchased the 3/8 anvil instead of the 1/2 anvil. It’s not a big deal I just have to accommodate by using an adapter only down side with an adapter is extra lost space in length. But overall all very impressed with the break away torque and the precision feature to prevent stopping or rounding. I’ve always been a big yellow fan boy and don’t plan on changing . Would recommend to a friend

                      Good quality best tool ever, i like it because it has good torque and is easy to handle I recommended a hundred percent for any of you needs
                      by
                      This is the first impact I’ve ever owned, so I have a limited frame of reference. Regardless I’ve been very impressed with it. I originally bought it to put in some lag bolts but since then I’ve used it to do work on my truck. It seems like you can get a little more power it when you have the space for it. Although there has been very few things that have put it to work even with a 1.7 ah powerstack battery.

                      Went with the 3/8 inch wrench because I use those those sockets the most. The 3/8 and 1/2 units have the same specs so if I need to wrench a 1/2 socket I will just use an adapter My 1st use was replacing my mower blade. So much easier and safer than a breaker bar and 2x4 to secure the mower blade. It was a breeze to take off and put back on. I got a good price match on my tool and faster delivery. Very happy with the tool.

                      Should have bought one of these years ago
                      So far I have used to change the blades on my rider, without taking off the deck! This thing is so compact it fit under when the blade was on highest setting saving me a lot of time. I used to to remove spark plugs on an old v8 engine. I had one plug that broke off and I used this to get it out with an extractor. After I broke one I used this to get the rest out and they all came out without issue. I love how compact light weight and powerful this thing is, will be buying one for my dad as well!

                        Pretty impressive for a compact
                        Decided to pick up this 1/2 inch impact and so far I’m pretty impressed. I used it to do a brake job on my wife’s car and it had no problems taking the lug nuts off. I also love how compact it is, fits into tight spots to get hard to reach bolts. If it’s like all my other dewalt tools it’ll last a long time.
