ACDelco ANI405 1/2-Inch Impact Wrench 500-Feet-Pound

On the lower side of the prices is this Acdelco ANI405 with twin hammer but significantly weaker punch than the first two items. The housing of the unit is aluminum alloy and is quite durable and able to take a pounding. If looking for a low priced item that can last for years the mechanics of the unit along with the materials are quite well built, even if they are less effective at the job. There are 4 total modes, with 3 forward speeds and 1 reverse speed. The exhaust design is creative and it’s built into the handle, which will take some getting used to if you’re coming from another design. It looks small but it is a bit of a hog, weighing 6.2 pounds and easily being one of the heaviest on the list.

The aforementioned weight becomes a problem since it doesn’t compensate with torque, which maxes out at only 500 ft. lb. The 1 year limited warranty isn’t really going to change anything since the unit itself is very well built and prone to damage. Air flow capacity isn’t too demanding at 4 CFM, which is expected since the torque is on the lower end of the models. This is on the bottom half of the air impact wrenches on the list, but may be favorable for those that don’t have a powerful air compressor. Even with the added benefit of being able to use a below average compressor there are going to be maneuverability issues with a tool that’s almost 7 pounds in total weight. It’s going to take some strong and steady hands to see a longer project through to completion, if at all. This is a good unit for someone that has an unreliable air compressor, any other reason than that and you can definitely find something better.

Ingersoll-Rand 2135TiMAX 1/2-Inch Air Impact Wrench

On the weirder looking side is this expensive Ingersoll-Rand that has 780 ft. lbs. of max power with a professional touch trigger offering variable forward speeds. The setup is so ingenious that they patented the forward and reverse buttons, which offer the best control of any unit on the list. Thankfully with all of the innovations it still is on the lighter side weighing in at 3.95 pounds. And this stocky little gem is not only durable but is protected by the MAX Protection Program where if you register the tool you’ll get a 2 year limited warranty. This isn’t the most powerful item on the list, but the weight to power ratio is tops on the list for a reason. The buttons are all in places where they’re easy to reach with one hand, so forward, reverse, and even changing the speed are all operational without compromising the user.

The compact design also features another patent, the Quiet Tool technology which makes it one of the most silent tools on the list. The casing of the unit is made of titanium, but you won’t notice it when you’re holding it. You’re more likely to notice it when it gets banged around, and still performs like a beast. There isn’t a plethora of accessories, and it’s pretty much going to be the tool and a manual to get you started. Putting in sockets is such a no brainer that in some ways it puts other units on the list to shame, based on how easy it is to use. Although this unit populates a lot of professional shops it has found a home in consumer garages as well, and doesn’t look to be going anywhere soon. Don’t let the look throw you off, this is clearly one of the best on the list. If looking at the features alone, can beat just about any on the market.

Ingersoll-Rand 231C 1/2-Inch Super-Duty Air Impact Wrench

This mid-priced unit from the same company as the previous item tries to stand out by having an exclusive impact mechanism that focuses on control rather than power. The power regulator however is adjustable, with pressure fed lubrication to help during long projects. The Ingersoll-Rand 231C will probably be the easiest unit you ever have to service due to the two piece construction.

Taking it apart is a breeze as well as locating whatever the problem is when it isn’t functioning correctly. With a contoured handle that feels as good as the best can offer it’s hard to hate this product, even if it is missing some significant features. It’s underpowered with its 425 ft. lbs. torque but has an air consumption of only 4.2 CFM. The weight is average at 5.3 pounds and won’t scare away the harder worker that’s worried about hand strain.

The design and actual model of the united has been continuously built upon for over 25 years. It isn’t necessarily a bad unit but pales in comparison to others like the previous, which is by the same maker. What this air impact wrench lacks for power it makes up for with control, but that is a pretty huge sacrifice if you have a big project to use with it. The warranty is a standard 1 year and requires a sales receipt or an invoice when registering. The max Psi for use with the tool is 90, but there is some wiggling room there if you’re willing to experiment. Make no mistake about it, this is still a great buy for someone working out of their garage and doing nominal hobby work. If you’re looking for something heavy duty that is also future proof, then it would be hard to recommend this tool to anyone. There are way too many great options at similar prices that you can spend your hard earned money on.

BOSTITCH BTMT72391 1/2-Inch Impact Wrench

The twin hammer mechanism in this low priced Bostitch will surprise you, as well as the durable aluminum body that can withstand a lot of punishment. Speed is handled through an easy to use adjustable power regulator allowing you to apply as little or as much speed as you need. Exhaust is expended through the bottom handle, so for users that have never had an impact wrench like that it will take some getting used to. The featherlike trigger of the unit will also take some getting used to, as you’ll have to get a general feel of when it clicks and when it doesn’t. Reverse has full power so if you need to remove bolts it’ll give you exactly what you need without stalling on you. The handle is as comfortable a cushion as you can get and also absorbs shock while in use.

Total air consumption is 3.9 CFM at 90 PSI and the unit has an overall weight of 5.9 pounds. Considering that this is on the heavier side of the units on the list and the torque is only 500 ft. lbs. then it’s safe to say it’s a little disappointing in that regard. You do however get a 3 year limited warranty that’s the longest on the list, so that is something to think about if you want a product that will last you for years. Bostitch also has great customer support, which is another winning feature of buying from this bigger brand name. Upkeep only requires a couple of drops of oil daily, which is easy to apply manually as stated in the instructions. You’re giving up a lot of power with this unit, and in situations there will be some bolts you won’t be able to get off because of that lack of power, even with the full power reverse. As a lower priced unit this will definitely do the trick for beginners, but anything beyond that you may want to look elsewhere.

Ingersoll-Rand 261 3/4-Inch Super Duty Air Impact Wrench

One of the highest priced units on the list is also the heaviest, and comes in at a hand shaking 13 pounds total weight. There aren’t many ¾ air impact wrenches that can deliver up to 1,100 ft. lbs. of torque, but of the few there are they weight a lot less than this brand. With the extra power and the jumbo power mechanism there won’t be a single bolt that can challenge you whether it’s in forward or reverse speeds. A pressure-feed lube system increases performance by making sure the mechanics of the unit are functioning at 100% at all times. The extra weight is due to this being a professional grade heavy duty air impact wrench that can handle the likes of major engine teardowns, pinion nut and track pad removal and spring work.

Due to the extreme nature of this unit it can almost be considered overkill for smaller tasks, as it tears through just about whatever you throw at it. The usual handle exhaust keeps unwanted things away from your face and shoots it down through the bottom while average air consumption is a hungry 9.5 CFM. As long as you have the stamina to handle the 13 pounds of this monster it will take care of any job you throw at it without any type of setback. Because of the extreme power of this air impact wrench there will be a lot of noise, but nothing to crazy out of the comfort zone of what you’re used to with these type of tools. The size is perfect and the design works well with your hands, while giving you enough control to manage even when at the highest speeds. Hook this up with a great air compressor and you’ll never need another air impact wrench in your inventory again. Even with the extreme weight, this heavy duty air impact wrench is one of the tops on the list.

Ingersoll Rand 2145QiMax Rand 3/4-Inch Composite Quiet Impact Tool

We go from high to higher with the highest priced Ingersoll Rand on the list, with a blistering 1350 ft. lbs. reverse torque from an air impact wrench that weighs only 7.4 pounds, about half the weight of the previous unit. It’s a small and compact tool that can get to places that some of the other tools on this list can’t reach, and even if it’s dropped it’s strong enough to withstand the impact and keep going. The two year limited warranty is standard on this model and will probably not be needed if you take good care of the tool. There is a 16 percent increase in motor efficiency so that you don’t experience any lag on tough projects, and with a 7 vane motor you’ll never be lacking for the power that you really need.

Cleaning of the tool is extremely easy because of the inlet screen, which in the end means you’ll spend more money operating at max efficiency and worrying less about a full functioning air impact wrench. Average air consumption is 8.5 CFM with 1,150 blows per minute, with noise level hitting the 91.1 dBA level at its peak. This gives you the power of the previous product without the extra weight, so there is definitely some advantages here in terms of features and improvement.

This is not only a fantastic beginner air impact wrench, but if you’re in the market to replace your current one then this is really the way to go. There aren’t a lot available that are this size, with this power, and massive set of features. It handles air very well for the power it draws and is a winner on all fronts, even with the warranty. This is a great buy and should not be overlooked, for either starters or experts in the field.

NitroCat 1200-K 1/2-Inch Kevlar Composite Air Impact Wrench with Twin Clutch Mechanism

As the second to last air impact wrench on the list, this is a great choice for ½ wrench users looking for a mid-priced solution with a load of features. The housing is strong, built with a Kevlar composite to withstand blows but still contoured enough to make sure the operator doesn’t get fatigued with a bad design. While most of the other options on this list are on the noisy side, this is the quietest of the bunch and only operates at 86 decibels with the patented quiet technology. A twin clutch mechanism gives you sound mechanics to back the power while the exhaust goes through the bottom handle to keep unwanted debris from your face. Forward and reverse are managed through a flip lever that’s easy to recognize and get to.

Marketing touts this as an air impact wrench used by many NHRA Top Fuel race teams, and it’s easy to why it’s popular. Operating PSI is between 90-120 with a max torque of 1,295 ft. lbs. to keep you busy on many heavy projects. If by any chance something goes wrong you get a 2 year parts and labor limited warranty to go with your product. If looking for variable speeds you’ll be a bit disappointed that even though it has different speeds there isn’t a lot of difference between the lowest and highest settings. This may frustrate some uses that want to do some fine tuning with certain projects, and may be more interesting in purchasing a unit that has true variable speed. The protective cover is bright red with flames, which looks cool at first glance but sort of takes away the overall professionalism of the unit. If looking for something that is an all-around champ, this works well for a variety of reasons. It’s quiet, powerful and can take on just about any other unit on the list.

There is also no fear with dirt or other miscellaneous debris affecting the tool and how it functions on a long term basis, thanks to the way the designed the housing.

The inside using a twin hammer mechanism with other features such as an ergonomically developed trigger, swivel air inlet and free speed 8,200 working torque.

Ingersoll Rand 2135Ti10YR 10-Year Anniversary Edition Titanium Impact Wrench, Titanium grey

Last on the list is this high priced limited anniversary edition Ingersoll Rand, celebrating 10 years of the IR Titanium impact wrench. You get 1100 ft. lbs. of torque with a unit that weighs only 4.8 lbs. for maximum efficiency and the ability to get in hard to reach places. Extras include a nice stylus pro flashlight and a one of a kind decal that not only looks great but is fun to show off to friends. Even as an anniversary edition this is still a viable ½ inch impact to use on a daily basis, and works great as a lifetime tool for those that work a lot in shops. The 120 volts is plenty of power and gives a consistency that does the model it is made after a lot of justice.

Other extras include a 10 year anniversary plaque with paperwork, so if you’re a bit of a completionist this will look good in your collection. With such a pretty outer casing it’s almost a shame to get it dirty, but beneath that casing is one of the most powerful air impact wrenches on the market. The noise is a bit on the unforgiving side, but is really average when you get down to it. But don’t expect some revolutionary noise silencing technology in this product as you’re going to get the standard. There have been some complaints that some of the accessories that are supposed to be included may be missing from the package. Make sure that if you don’t receive the flashlight, the plaque, and other mentioned accessories to contact support to correct the problem. It’s not often I can recommend special anniversary editions as full day to day working tools, but there are always exceptions to the rule. This is very much a great buy if you’re looking for something long-term that won’t give you any headaches.


Those were some interesting choices for, especially considering one of the best choices is a monster that weighs almost 15 pounds! This isn’t a deal breaker for some but may be for those with arthritis or other hand conditions. Surprisingly the largest on the list wasn’t the most powerful, and when it comes to being the quietest then the NitroCat with Kevlar is king on the list. With the great choices on this list you will come out on top no matter which one you choose, so have fun and prepare to be amazed with the power in your hands.
