          While in fastening, each mode has a tiered approach to torque values that scale up with each mode. Does the tool also have a tiered approach to torque in breakaway or reverse? Or, is the tool using a full 1,300 in all modes?

          Answer This Question

          Hello, Jonm - The modes are representative of RPMs, not torque. The breakaway torque of the impact wrench is 1300 ft-lbs. regardless of what mode you are in (and fastening torque is 900 ft-lbs.). The ranges are as follows: Auto mode (A) 0-1,100 RPM, Low (1) 0-600 RPM, Medium (2) 0-1,300 RPM, High (3) 0-1,800 RPM. If you need further support, then feel free to ask another question.

            what is the torque specifications for the three independent modes (1,2,3)? Obviously on mode 1 the torque output is less, but I don't see these specifications anywhere. Just 900 ft lb of fastening torque and 1300 breakaway torque.

                  This one packs a punch. I have a smaller stubby impact that just doesn’t always get the job done. My neighbor has this Ridgid high torque impact and I have had to borrow it when I find myself needing more torque. Most recently I was doing my brakes and had a problem with one lug. I tried my 550ft pound stubby and ran it until the tool, the socket, and the nut was hot. After trying and failing a couple more times I called my neighbor to get his ridgid and told him” if this gets this lug off I am buying me one”. I put the ridgid high torque impact on the lug nut and it hammered literally 4 times and the lug was coming off. Later that night I logged on to homedepot.com and purchased my own. This tool is large and is a bit heavy so it’s not something that you would want to use all day or in tight spaces. It is for those impossible to remove bolts that nothing else will get off. I have removed rusted exhaust bolts and hub bearing nuts with ease using this tool. I have not ran into a bolt that this thing won’t remove. It’s performance is as good or better than the much more expensive brands. And when you factor in its lifetime warranty it’s hard to justify buying anything else.

                  Incredible power for the price. The brushless motor is efficient, and the 1/2 inch drive feels very heavy-duty. I love the 4-mode versatility for different torque needs. It’s a bit heavy, but that’s expected for this much power. The included charger and dual batteries make this kit a steal.

                  Combo price was amazing, impact is more powerful than I expected it to be. Easily removed lug nuts with minimal hammer action. It is physically large and quite heavy before the battery is even attached but has a quality feel to it. Price and the Ridgid LSA make this impact a no brainer.
                  by
                  The RIDGID 18V Brushless Cordless 4 Mode 1/2 inch High Torque Impact Wrench is a powerful and versatile tool. It easily removes stubborn nuts on both cars and trucks without hesitation. One feature I really appreciate is how well it works for removing and installing a trailer hitch ball. The torque is strong enough that there’s no need to hold the ball with a pipe wrench, which helps prevent damage to the ball itself. The cordless convenience and impressive power make this tool a great addition to any garage.
                  by
                  I just got this and have used a few times. It removed a old rusted bolt with ease. I thought it would be a pain to remove. High recommend. The convenience of it is also grade a. No more hooking up and running air lines out to work area

                  This half inch 18v impact gun was quite the deal! Two batteries, a charger, and the tool delivered for $199 plus tax. Add on the free lifetime service I had to buy it.

                  I really like my rigid half inch impact I use it at work all the time it performs above and beyond what I need I do tire technician work no problem at all I like the multivariable speed functions I like that the batteries are interchangeable with all rigid products A Plus in my book I've had it 3 months now use it all day everyday and it does very well
