Chicago Pneumatic CP7731 Air Impact Wrench (3/8 Inch), Air Impact Gun Industrial Repair & Assembly Tool, Pistol Handle, Single Hammer, Max Torque Output 306 ft. lbf/415 Nm, 6400 RPM

Small yet very powerful! I've had a Snap On XT7100, MG725, CT 4850, IR 2115QTI and have used an IR 2135Ti Max, IR 231C, and Matco MT1769A.I decided to buy this impact just because I'm a guy and like my toys. I compared this stubby against other popular stubby impacts in the market right now: Mighty 7 NC-4232Q, NC-4610, NC-4611Q, NC4630Q, AirCat 1055-TH, and Astro 1822. I was originally considering one of the M7 impacts or the Astro 1822 due to max advertised working torque and the size as I wanted something super small in case I needed to get into a tight spot. Then I found torque test videos by Real Tool Reviews on YouTube ( I found a video by AirCat testing their gun against the 7732 and one of the M7's but I will trust an unbiased, third-party tool geek before I trust a manufacturer ) which pushed me to consider the 7732 and eventually purchase it even though it's a little bigger than the other stubby impacts. I'm happy with my purchase and just hope that I never come across anything that's too tight for this impact to get to.I've gotta say that the amount of control alone goes (trigger sensitivity and anvil wind down), it's as good as my MG 725 and CT 4850. There is hardly any wobbling of the socket once you pull a nut off a bolt which was my biggest pet peeve with the IR 2115 and 2135. In an automotive setting, many times customers will come in with aftermarket wheels with tiny lug nut bores that require a thin wall socket (if it's the standard hex lug nut) and with the 2135, I've scratched some bores up and had to send them out for repair. The MG 725, CT 4850 and the stubby CP7732 don't exhibit that problem much. There is still a slight wobble but it's very small.As far as power goes, it's no MG 725 or 2135 but it feels just as strong, if not stronger, than the iconic 231C. And the best part is that it's very compact and light so there's not much strain on your wrist compared to full sized impacts that, while light in comparison to old school guns, are about 2x the weight of this unit.I'm currently using cheapy HF fittings in conjunction with a HF 60 gallon compressor (15.8 CFM @ 90 PSI ) but will be going out to buy Milton V type fittings soon to see if there's a difference and will edit my review once that is done.

Bought this gun to replace my Milwaukee 1/2 inch high torque. The gun has been perfect for zipping lugs off with great control for the power it holds. Was impressed enough with how much power was in its compact build I ended up getting the 3/8 version. Great for caliper bracket bolts and even front engine work on Toyotas. All around it’s a very good tool for the price and I’ve been happy with it so far.

Impressive power for such a small and light weight gun. Build quality is top notch as I would expect from CP. This little "toy" as one of my coworkers calls it has in my opinion as much power as an IR231 with half the weight. I would not use it as my everyday work horse just because it can't possibly be as durable as a full size gun, BUT for those days when my wrist is so sore the thought of holding a 6 pound gun in my hand makes me cringe, I'm glad to have it available!!!!!!! Time will tell how durable this thing is but everyone who has tried it has been blown away by the sheer power of this thing! It just sounds mean! Subaru crank bolts come out easy as pie.

this is certainly a small & powerfull impact... impressively small and powerfullthe Chicago Pneumatic CP7732 has a hair trigger and instantly goes full power.. no control at all.The FWD & REV switch is a teensy fragile looking plastic lever, it broke after 6 months use.I just a gage on my air hose & I am running 110PSI The gun is rated for 90.I also have a Ingersoll Rand 231C that I have used for years.... part of what I like about it is the controllable throttle.you can ease in a very small bolt with a light touch on the trigger with this big heavy old school impact gun.

These are great, I use mine every day at the shop. They don’t have the break away torque you need for a stuck crankshaft bolt. But they are fine for suspension work and axle nuts and lug nuts all day long. They also fit in a lot of places big guns don’t. For the price they are awesome. You do have to be mindful of the setting you are on. You can roll the wheel to a lower power setting accidentally. Just have to watch it.

Good powerful impact wrench for tight locations. Biggest problem is it is so much better than my other impact wrenches that I catch myself using it for everything. I'm a professional diesel mechanic, and in the shop I work at my coworkers have practically every brand of impact wrench made so we compare notes. This wrench isn't cheap, but it is worth the money because of how well it works. You aren't saving anything if you buy cheap tools that don't get the job done. This wrench gets it done.

My supervisor has the 1/2" model and I have borrowed it a few times and I fell in love with how small it is yet still has enough power for the task at hand. I already have 1/2" impact so I got this little guy in 3/8 because I needed something small yet powerful enough to do the job. I got it just in time because I was finishing up a rear main on a DT466E. It made putting everything back together so much easier, was able to get the top bolts of the transmission without breaking my hand or arm, and was able to not worry about it having too much power and stripping threads.

Has not broken free one fastener that I have need an impact wrench for yet. The +400 lb-ft reverse spec is way off since this would not remove bolts that were torqued at 90 lb-ft. Save your money for a real impact wrench unless you are looking for a unique paper weight.
