Best Ingersoll Rand Impact Wrench Review and Buying Guide

An impact wrench is a wrench used to loosen and remove tire and engine bolts without needing a tire iron. Air impact wrench tech is different from cordless impact wrench tech. Unlike their cordless or corded counterparts the air variant doesn't use batteries or electricity.  Its power source is compressed air and a simple vane motor with 4-7 vanes plus various lubrication systems.

It works by delivering high torque output with minimal exertion on your part by storing energy in a rotating mass then suddenly delivering it to the output shaft in one fell swoop. As for the Ingersoll Rand Impact Wrench, it's the brand trusted by professionals and has high-ratings among do-it-yourself home mechanics because of its ease of use and versatility. If you want an air impact wrench that lasts, then you should look into getting one of the several Ingersoll rand units reviewed here.

With that said, which Ingersoll impact wrench model should you get?

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

The Ingersoll rand 231c has a product design reminiscent of the classic ones you'd see as the standard when it comes to Ingersoll air impact wrenches in particular and impact wrenches in general. It's utilitarian and doesn't have anything fancy added to it, which makes it more practical and functional in terms of longevity, performance, and power. The average DIY mechanic can get a lot out of the ir 231c with minimal effort on his part because its twin-hammer mechanism delivers 600 feet-pounds of maximum torque, making short work of any tire bolt or engine bolt.

According to customer reviews, the wrench allows you to do things like change four blades from your mower in next to no time with a simple pull of the trigger. Even though it doesn't use batteries, the unit's twin-hammer mechanism and torque of 600 foot-pounds deliver enough compressed air power to get the job done. If you're worried about the Ingersoll rand impact 231c, the adjustable power regulator allows you to control the torque output right down to the last digit so you won't end up over-tightening any screws or bolts to the point of damaging them.

It doesn't come with a battery because it's an air impact wrench that uses air and pumping action to make it work. Also, the 231c Ingersoll rand comes ready to use right out of the box because it arrives fully lubricated from the start. Its method of lubrication is the pressure-feed variety as well. For what it's worth, some customers from the web also admire this Ingersoll impact wrench for its aesthetic design, calling it a "good-looking wrench". That's a subjective conclusion, but objectively it's designed to maximize grip comfort and be compact enough to fit inside the nooks and crannies of your car from under the hood or underneath it. It has gotten some complaints in regards to its weight though.

Although Ingersoll has done what it could to balance out the unit's ergonomics and space-saving capabilities with its high-impact, high-torque operation, your hand can only take so much from using it before it gets tired. It's also not going to be too lightweight at 6.5 pounds. Your hand will take a beating from the 8,000 RPM motor of the 231c as it delivers impactful bolting and unbolting. However, aside from this weakness that lowers its overall score a little, it's a dependable device according to many. Also, some quality control concerns are afoot as well in regards to some units unable to stop turning or require an inordinate amount of lube, but they're usually the minority of the units shipped.

 The Ingersoll rand model 231c also has an adjustable power regulator, which you can use to control the torque output according to the specifications found on your car manual in regards to certain nuts and bolts. It's also ergonomic for the sake of keeping your hand from getting tired from holding it for too long during mechanical operations. This also allows you an easier time maintaining it. As far as this Ingersoll rand 231c review is concerned, it's a good DIY impact wrench for beginners that are just starting in doing mechanic work on their ride or other equipment. In terms of what's in the package, you get the unit itself alone.

2. Ingersoll Rand 2145QiMax 3/4-Inch Composite , Quiet ImpactTool

As for the Ingersoll Rand 2145QiMax, here's the lowdown. Compared to the 231C, the Ingsoll 2145QiMax is just a little bit better in terms of raw specs and numbers. Check and match their specs with each other to see for yourself. The 2145qimax is capable of unbolting bolts and removing nuts quickly with its 1,350 feet-pounds of torque while the 231C has 600 feet-pounds of maximum torque. Moreover, the Ingersoll rand 2145qimax also has 930 feet-pounds of maximum reverse torque for good measure. Both models make use of the Ingersoll's signature twin-hammer impact mechanism that allows them to work without the need for batteries.

 It's also every bit as durable as the 231c since they've been made by the same manufacturer and customer reviews echo similar sentiments from the two models save for some units with quality control issues. The 2145qimax Ingersoll rand specifically belongs to the Ingersoll Rand 2100s Series that have units specifically made to be tough. This particular model features a square driver type that's also a hog-ring. What the 231c notably lacks that this unit lacks is a titanium hammer case that keeps it safe and mobile versus the simple box that the 231C comes with. This case protects the tool from harsh environments, making it useful in both car repair and industrial-level work at the construction site.

What this particularly means for the average DIY mechanic who wants to make it easier on himself to remove bolts from the car battery or on the tire is that the Ingersoll rand impact 2145qimax can last them a lifetime. It's because they're built to survive industrial-grade operations and simple tire removals and DIY car repair aren't as intense as that line of work. Aside from both the unit and the hammer case being made as durable as possible with Ingersoll Rand technology, this powerful air impact wrench also has a lightweight design. Or relatively lightweight in light of the 231C weighing lighter than it is but its closest competition weighing much heavier.

According to customers who've made 2145qimax review posts, they're able to last when handling the power tool, but like in the case of the Ingersoll Rand Impact 231c, their hands do get tired from using it. If there's one thing the 231c can outdo the 2145qimax on, then it's ergonomics and lengthy operation because they feature similar designs, but the QiMax weighs a pound heavier than the 231C. Ingersoll Rand did what they could to minimize fatigue when using their impact wrenches. By all intents and purposes, the Ingersoll Rand 2145QiMax is considerably lighter compared to many all-metal impact wrenches on the market to date.

It's heavy enough to be as durable as a tank though. What this means is that if you were to drop the unit accidentally from 5 feet or so multiple times, it would still keep on working with few scratches like an old-school Nokia 3310. Furthermore, everything fits together tightly, include the knob at its back and all its plastic buttons. However, its unmuffled version is loud although not excessively so. The most negative thing that can be said of this impact wrench is that a certain number of defective units have left several reviewers unsatisfied with the product.  In terms of what's in the box, you get the Ingersoll rand model 2145qimax unit plus the titanium hammer case, which adds value to the whole package.

3. Ingersoll Rand W7150-K2 1/2-Inch High-Torque Impactool, Charger, 2 Li-ion Batteries and Case Kit

Even though the Ingersoll Rand W7150-K2 ½-Inch High-Torque Impactool uses batteries unlike any of the other air impact tools on this list (thus making it a cordless impact wrench instead of an air impact wrench), it still ended up on this list because of its utility and its two long-lasting Li-ion Batteries (plus charger). More to the point, the Ingersoll rand w7150 is probably the Ingersoll Rand model featured in this article that could keep up with the highly rated Ingersoll Rand 2145qimax. It's several times better than the 231c with it featuring both high torque and reverse torque at 1,100 feet-pounds and 780 feet-pounds respectively.

Alas, it still falls short against the popular and highly rated 2145QiMax Ingersoll Rand Impact Wrench for several reasons, chief among them the need for batteries and charging. Sure, some DIY or professional mechanics out there might not mind the extra charging time from the w7150 as though they're charging their smartphones. However, the 2145QiMax is the unit you can use whenever you want, thus allowing it to go up a few notches in our eyes in terms of utility. As for the Ingersoll rand w7150-k1, it is practically the same as the Ingersoll rand w7150-k2, but with several notable exceptions. The w7150-k1 model has both specs for maximum torque and reverses torque at 1,100 and 780 feet-pounds respectively (that comes short of the 2145QiMax's 1,350 and 930 feet-pounds respectively).

Ingersoll Rand W7150-K2

As for the w7150-k2 model, it only has 1,100 feet-pounds of torque for busting some bolts and nuts. It's impressive for a tool that weighs 6.8 pounds, which is about 0.3 pounds heavier than the 231c and 1.3 pounds lighter than the 2145QiMax. Both the K1 and K2 models weigh the same. Both also feature durable designs that can take a pounding, accidental drops, and long operation, but K1 has a case to further ensure its protection. The Ingersoll rand w7150 k2, however, has metal-reinforced housing, an all-metal drive train, a high-capacity variable speed trigger, and a high-efficiency rare earth magnet motor that all work hand-in-hand to make operate efficiently even in rugged conditions like construction work or working at a factory.

Both models also ergonomic handles and soft-touch, over-molded grip to make sure you can hold unto them for as long as possible without tiring your hand, palms, fingers, and arms out. K2 goes above and beyond K1 though with its Intelligent Battery Management System or BMS. This gives the w7150 k2 more current control from the battery and a power level indicator so that you won't run the ragged or beyond its limits. The units also feature a 20V Li-ion 3.0 Ah batteries designed to deliver low internal impedance and high-charge capacity for your impact wrench.

What this means is that they ensure maximum power delivery and run time from your power tool with no wasted charge. As far as this Ingersoll rand w7150 review is concerned, the K1 version is closer to the 2145QiMax than the K2 version due to its maximum reverse torque spec and its container case. The only bad thing that can be said of the cordless 7150 is that it also has defective units that lost RPM then started smoking from seeming overuse, resulting in damage beyond repair. For both the W7150-K1 and W7150-K2 units, their respective packages typically include the unit itself, 2 Li-ion batteries, a charger, and the case kit. Again, the K1 unit has a steel-lined aluminum, blow-molded hammer case to boot.

4. Ingersoll Rand 2115TiMAX 3/8-Inch Impactool

Last but not least is the Ingersoll Rand 2115TiMAX. This mostly plastic impact wrench is the weakest one on this list. It has a max power of 300 feet-pounds of maximum torque. However, it's not supposed to compete against others in raw power. Rather, it's been Its feather touch trigger allows for immediate responsiveness when you wish to use it. However, the 2115timax doesn't compare to the torque specs of its Ingersoll siblings, the Ingersoll Rand W7150 (both K1 and K2), the Ingersoll Rand 231C, and the Ingersoll Rand 2145QiMax impact wrenches. The Ingersoll rand 2115timax is the best in its class, but to compete with the others on this list is equivalent to a boxer punching above his weight class.

Included on this list because it offers a viable alternative to the abovementioned impact wrenches powerhouses. It's the impact wrench that only weighs less than 2.5 pounds and is only 6-inches long. This Ingersoll rand 2115timax review wishes to emphasize that the 2115Timax is the one-handed impact wrench you can use for longer periods at narrower nooks and crannies to deal with smaller bolts and lighter torques. The abovementioned wrenches can be too power with their torque or too large and heavy in size to do the fine-detail bolt and fastener removal from under your hood.

Ingersoll Rand 2115TiMAX

What's more, because it's an Ingersoll Rand power tool, customers can expect best in class power performance from the 2115timax Ingersoll rand pound-per-pound. It might have less torque than its larger counterparts, but it packs a lot of wallops when it comes to nut-busting, unbolting action when fixing cars, mowing equipment, and other heavy-duty appliances. There are two variants of the 2115Timax—the 2115TiMAX and 2115QTiMax. The 2115QTiMax mostly differentiates itself from its Q-less impact wrench counterpart by having better muffling tech. It's a lot quieter to operate. In other words, design-wise, the QTiMax is the most silent impact wrench on this list.

The wrench also has a host of power regulator settings in the forward position while also providing maximum power in reverse. Thusly, users like you can get power and control of that power from front to back from the Ingersoll rand 2115. This works excellently with its new 7-vane motor that adds more oomph and torque for an impact wrench of its size. You can even use it one-handed, which can get painful real quick when you do the same to the other Ingersoll Rand impact wrenches on this list. Its compactness, tank-like design, and lowered torque also mean its vibration is at a low 7.5 m/s2.

 As far as this 2115timax review is concerned, the main downside to the unit is that a handful of defective units actually came apart from the strength of their motor. Quality control wasn't able to check how put-together their assembly was, resulting in a motor so strong and a body so weak that the trigger came right off according to at least one customer who bought it. Some orders didn't come with sockets and cases as well. Still others didn't live up to the specs, thusly underperforming. Inside the box is the unit itself. No batteries included because no batteries are needed.

5. Conclusion

If we were to rank the models from "best" to "worst" (relative to the models being reviewed by this article) air impact wrench, we'd end up with the Ingersoll Rand 2145QiMax in 1st place, the Ingersoll Rand W7150 in 2nd place, the Ingersoll Rand 231C in 3rd place, and the Ingersoll Rand 2115TiMAX in 4th place. What is this ranking based on? Customer reviews and our estimation of the products when we got our hands on them. Mind you, this is relative to overall utility and doesn't cover specifics where they'd shine, like the 2115TiMAX's usage in narrow spaces and for smaller bolts.

The Ingersoll Rand 2145QiMax wins because it doesn't use batteries, it comes with a tough titanium hammer case, its hammer case seems redundant because of how tough the unit itself is against accidental drops, it has a favorable maximum reverse torque spec, it's quite ergonomic for an impact tool of its size, and it's probably the most powerful yet controllable impact wrench of its class and size. It is pound-for-pound the best one on this list in our humble opinion.
