Campbell Hausfeld XT002000 1/2" Impact Wrench - Heavy Duty Air Tool for Automotive Repair & Construction | Perfect for Tire Changes, Bolt Removal & Mechanical Work

First and foremost - this impact driver was $50. FIFTY LOUSY DOLLARS!! Therefore, negative reviewers, there are almost NO grounds to complain if it doesn't work perfectly - or even well.On my first use this thing blew my mind! I have a Ryobi One+ 18V cordless impact driver rated at 100 ft lbs. I love the thing dearly and have put it through things it should never have been put through in two hard years of use. It has never complained, but it only puts out 100 ft lbs of torque. I have been limited by this enough times that I was looking for a better option. The NiMH batteries on my Ryobi are getting old and for $100 I could upgrade the battery (singular) and charger to Li Ion, but the torque spec would not change. Any time I've hit a wall I've had to borrow my friend's plug-in DeWalt impact driver (rated at 350 ft lbs and costs about $150). This has happened enough times that I thought I should upgrade my own equipment. I almost peed my pants when I saw a pneumatic driver rated at 550 ft lbs for just $50! Who cares if it worked well. It should at least be able to torque out more than 100 ft lbs, which is all I needed anyway!So I read all the negative reviews and they sounded like there may be legitimate concerns on quality with this CH driver - but if one tests it right away one can return a defective product. So I bought it. Right after I got it I put it to work on my post-and-beam chicken run. The structure is build, but there were several (nine) 6" construction lags that my Ryobi just could not sink. I got that DeWalt plug-in driver to finish things off, but I left nine lags not as torqued down as they could be. This was in order to get the loaner back quickly and because I thought things were "good enough." Well the "good enough" seemed less-so over the intervening weeks. Now that I had a new driver, why not test it out on them?I was a little surprised at the stringent requirements for both lubrication and air supply as I read the manual (I've never had a pneumatic impact driver before). The manual is all of three pages long and almost all of the troubleshooting (fills most of one page) goes back to lubrication and air supply. I couldn't help but wonder how many of those negative reviewers did (or didn't do) their due-diligence in these areas.LUBRICATION - Oil the air motor before and after each use. They recommend 1/4 oz of oil, which seems ludicrous to me. But that's what's called for. I probably did a little less. - Impact mechanism: add 1/4 oz of oil, cap, then run the tool for 20-30 seconds while moving it around, inverting it, etc. Then drain any excess, recap and you're good to go. I didn't add 1/4 oz because the opening is so small I had to add oil one drop at a time. But I probably added 80-100 drops. Nothing has come out yet. Maybe I'll just keep adding each time I use it until some does come out?AIR SUPPLY- Do not use quick disconnects. Whatever. I added one.- Use only fittings and hoses with 3/8" ID. No idea. My hose was given to me and it has no markings apart from the pressure rating. It could either be thick-walled 1/4" ID or thin walled 3/8" ID. Regardless I'm sure the quick disconnect I added is a 1/4" ID at the orifice.- 90 PSI max, and supply at 3.4 CFM continuous. I did this. My compressor has a 17 gallon capacity (on the primary side of the regulator the supply pressure is 150 psi).FIRST USEI charged up my 17 gallon compressor (at 150 psi, regulator set to 90) and wheeled it off (unplugged, no electricity) to the chicken run. I sank the nine 6" construction lags using this gun anywhere from 1/4" to 3/4" depending on what was needed. I figured I'd just run the tank out.These lags were all driven by the Ryobi so I know they were stopped at the 100 ft lb torque mark. The CH driver effortlessly continued the job. It ran slower than I'd expect a 550 ft-lb rated driver to go - BUT! I have already mentioned I was running against manufacturer recommendations with my small quick disconnect (and possibly the air hose ID).CONCLUSIONStill with the ease it torqued the lags down. Having used a 350 ft lb DeWalt electric on the same type of lag connection I'd estimate the CH is operating between 200 and 300 ft lbs.If I want more torque I can buy upgraded hoses and connections. But frankly all I wanted was MORE than 100 ft lbs. For $50 I have that, even with improper air supply.Additionally when I was done with that job the primary side of my regulator was at 120 psi. So I used 30 psi in a 17 gallon tank to do the final sinking on nine stubborn 6" construction lags. This strikes me as a very efficient pneumatic tool. My 4" cutoff tool (rated at 5 CFM @ 90 psi) is FAR more of an air hog than this gun.For $150 I would be very happy with this gun. It's far smaller and lighter than the DeWalt plug-in. But to get this performance for just $50 - and to know that performance can be further increased if I so chose - I am super happy with CH!I will be using this on every heavy duty application I have. I'll update the review as experience dictates.UPDATE - I used this to take off ancient, rusted bolts off an exhaust system that failed on me. I used plenty of PB Blaster and my trusty Ryobi impact driver to try to break the O2 sensor nuts off. No dice. So I got this CH out again and put it to work. When the nuts broke free I though I was again impressed with it's performance. Imagine my surprise when I found the nuts and NOT broken free. The CH driver simply sheared the O2 sensor mounting studs off the exhaust pipe with the nuts still attached!I'd say it has more than adequate performance!Product exceeded expectations. There were conflicting reviews mentioning 4.7 SCFM @ 90 PSI and 3.4 SCFM @ 90 PSI. The owners manual and the package both state that the unit requires 3.4 SCFM @ 90 PSI. That is an important piece of information when selecting the right tool to ensure you get the desired performance. I have a 20 Gallon 4.0 SCFM @ 90 PSI Air Compressor and the unit worked exceptionally. I used the unit for 3 solid days performing multiple jobs. It removes lug nuts with ease and had plenty of power to spare.Make sure you have the proper fittings as none are included. You have two basic options either industrial or automotive fittings. Automotive fittings are larger and allow more air flow meaning more power. It is important to note that the tool is designed to work at 90 PSI working power. That doesn’t mean set your PSI to 90 and go to work, what you’ll want to do is set the tool PSI setting to 90 then squeeze the trigger and see what the actual working PSI is (what the gauge reads when the tool is in use). You’ll want to adjust that settings so that you are at 90 PSI when the tool is in use. That will ensure you get the desired results and performance of the tool.I believe with the proper maintenance this tool will last for several years. Very well made and easy to use. I highly recommend.I was a little iffy based on some reviews but took the plunge anyways and the product exceeded my expectations, works flawlessly removing lug nuts. I made sure to remove all 4 tires just to be sure it was not a hit and miss. The manufacturer recommends using a compressor with a tank capacity of 8 gallons or higher, I used a 6 gallon capacity tank, they recommend not using a quick connector, I use a quick connector and even so it removed the lug nuts effortlessly, I even used it on a friends car to remove all 20 lug nuts some of which were rusted on and it did not struggle. The reason I cannot give it 5 stars is due to what I see as a design flaw, per instructions on lubricating the impact mechanism, you put 1/4 ounce of oil in the oil port after removing the screw but that pin hole is so small rendering it impossible to get that amount of oil in. I've gone as far as using a syringe but to no avail.My old ingersol rand gun finally had enough, and I saw this for sale on here. This is identical to the IR gun... it is literally the same thing as a 225 dollar air gun but rebranded. Cornwell sells the same thing for around 400 but with their name/logo on it. I even use my IR protective cover over this.. I think you get what I’m saying, this gun is very good. I use it daily and maybe I’ll oil it here or there if I remember, but that’s about it, and it never hiccuped even once. Obviously if you are using a really small compressor you’re going to have issues, which makes reading reviews on air tools really misleading. Anyway this gun is awesome it’s $50 and has plenty of power. I use it daily in a shop taking the wheels off cars all the time.This is a great buy for under $70. A tool that every driveway mechanic needs.Works great with smaller compressors. I use at home with in my driveway.My compressor only pushes 4.3 SCFM @ 90 PSI and 6.1 SCFM @ 40 PSI and can easily power this impact wrench to remove a spindle nut that hasn't turned in over 15 years.I broke the nipple off of my breaker bar and 1/2" ratchet trying to get a spindle nut off.5 seconds with this impact wrench and it was spinning around on my driveway.I definitely recommend this tool to intermediate level mechanics. It will save you a lot of time and frustration.GuaranteedI put 4 stars for durability because I've only had it for 2 weeks.You need to buy the male fitting that plugs into the air line.Bought this wrench primarily to change from summer to winter tires and back in the spring. It removed the wheel nuts with ease. The different speed settings allows for the lug nuts to be tightened in stages, the lowest setting to first gently snug the lug nuts, the middle setting to firm them up and for final tightening I switch to my torque wrench. This wrench replaces a Husky impact wrench that was useless.Pro'sReasonable Price, light weight for an air impact, fairly rugged construction.Con'sWeak loosening torque [I'd say around 100-125 ft/lbs at 90ish PSI-high CFM compressor], After using in a shop setting daily for 2 months the internals "hammers" are starting to show signs of wear.AnalysisIf you need something that you want to use at home or light duty applications this unit will suit your needs.Although I have not used it extensively over time yet it worked fine to change my tires.Using a hand tire wrench would have been back breaking.The good news is it even worked with my 3 CFM 4 gallon pancake compressor. No problem.I don't understand people saying it's not powerful enough.Excellent. I bought to get wheels off faster and easier in the garage. No complaints. If you have sufficient CFMs as per what its rated for, oil regular it as per instruction its a great home one. Not a commercial garage standard, but great for doing some stuff at the house.Funciona bien, pero tiene poca fuerza, aunque no se si se deba a la compresora, yo la uso con una compresora Truper de 50 litros y le falta potencia para extraer birlos de llantas, tengo que aplicarla 2 veces por birlo (a 150 PSI) para poder extraerlos, en otras aplicaciones que no requieren tanta fuerza funciona bien.
