ARI20132 1/2" Square Cordless Impact Wrench, with 20V Battery and Charger, 2,800 RPM Brushless Motor, 340Nm Torque, 0-3,300 IPM

While I am not a pro, I do have to do the odd DIY task around the house, so don't really need a fully featured cordless drill set. So this set by ACDelco has been really good for what I would typically do. I have already used it for two basic jobs. The first one was to drill a hole into an IP waterproof box. I already had a special bit for drilling a specific sized diameter hole into plastic. My bit fit into the chuck (I think that's what it's called) on the drill. So I'm assuming that this is universal. The second job was to put together a heavy table that used thick screws. One of the bits that come with the drill set fit the screws perfectly and I used the drill for tightening the screws. The drill itself has some weight to it and the plastic that it's made from feels super tough and durable. The mechanism for connecting the battery to the drill feels really strong as well. However, the power supply for the battery is just a small thing that doesn't feel up to the same build quality of the drill and battery. I would be very carful handling the power supply and it's not something that you'd have floating inside a tool bag. My only real criticism is that there is no case for the drill and its bits and battery. It would have been nice for it to have been supplied with a nice tough, purpose built carry case. However, I suppose that would have bumped up the price. I have an old heavy duty satchel that I am using to store and carry the drill, battery and bits. I don't think this would be suitable for anyone into heavy DIY and I wouldn't use it for serious commercial work. However, for typical light home use DIY I think it's fine.

This is the first time I've used ACDelco products, and I have to say that to me, it's a big step up from the usual cheap supermarket "special deals", I normally go for. The wrench is quite heavy, moreso with the Makita style battery attached, but this is a good thing as it gives it a bit of leverage to resist the torque when removing wheel nuts. Quality wise, it seems well built and rugged, not pro workshop level rugged, but considering it was a fraction of the cost (this was £60 at the time of ordering), it feels well balanced in your hand. The kit comes with a lot of various bits and drills in addition to the wheel nuts socket, expanding it's functionality, but I found that it felt like a bit of an after thought. The socket for the drill and screwdiver bits isn't held in place properly resulting in a wobble, not great when drilling?. Functionality wise, it still performs well as an impact driver. It has 3 speed settings, both forward and reverse, but it also has an automatic reverse where each trigger pull does a short spin, providing better control on seized bolts. Having not uses an impact before, I was a little worried it may break your hand if used wrong. This wrench shouldn't even go close to doing that, even by squeezing the wheel socket and using top speed, I was able to stop the wrench and I could hear the ratcheting sound you associate with a garage. Overall, I really liked this tool. The fact that it has extras over a normal wrench is an added bonus, but I'd personally prefer a good carry case instead of the cardboard box it comes in... or a reduced price?

I have an impact driver and use this a lot in my diy. I did read about these impact wrench being a significantly more powerful version. It feels like a solid bit of kit and seems to have a lot of more power when compared with my Makita impact driver. I felt the power is controllable so was confident of not over doing screws or bolts. This is what I would be using this for. Probably screws is a little too easy for it. You get a kind of a Makita type battery which charges with a socket on the battery instead of sliding into a charger. There is an adapter to allow you to use your hex screw bits as well as an adapter to use with your socket set. I was not too such about this but the battery interface looked like my Makita one and it does seem to accept Makita batteries and does work. The only annoying problem I found was that the adapters had a bit of a wobble so when you are trying to use at speed then it becomes a problem but if you hold the end still and slowly drive then this gets around it to a certain extent. For the price of £60 and what you get, I still feel this is good value for such a device despite the adapters not being spot on.

This is a very strange tool. Its from a huge brand name (AC Delco is GM's Parts department in the USA) who do produce some decent tools in the US at least.. But its not a common brand here in the UK at all so I was super interested to see what this was like. The answer.. as always in complicated. Straight out of the box.. the tool feels decent quality, well balanced and put together, so I thought we might be onto a winner. I then saw the battery, its charger and the accessory package.. And they scream supermarket tools! The battery charges with a DC wall wart style adapter, via a Barrel jack that you insert into the end of the battery between the contacts, in the style of all the cheapest tools you can buy. The battery looks very similar to a clone Makita in terms of the fitment and connections (apart form the DC barrel jack of course), we will come back to this later. The supplied accessories are also a bit confusing.. theres a selection of wood and masonry drill bits with a 6MM Hex shaft, and a selection of impact rated (hopefully) screwdriving bits, as well as a really quite nice 1/2 to 6mm adapter. While I have no problem using an impact for screws.. its not the tool I ever reach for to drill anything, and the inclusion of the drill bits here makes the whole product seem a bit strange. In use however this is a pretty decent little impact, its better than my Worx and up there with my Makita.. which I found unsettling. I also tried it with the Makita battery, which works perfectly, and for under £60 if you have Makita batteries around already, this is a really nice little impact. The body is slimmer in the hand than many, and it feels really well balanced. I actually really like it. I just wish the accessories and supplied battery could be omitted for a tool only item at a lower price as this could be something of a bargain!

This impact wrench seems to be very plasticy, that said there seems to be a good selection of accessories. There is 22mm chrome vanadium socket, a square to hex anvil adapter, 8 hex drill bits and 6 hex driver bits so everything you need really to do a variety of jobs.

Good for DIY and home use, it will make life a lot easier with undoing wheel nuts but I would still use my torque wrench to crack open tight nut or tighten the wheel nut to spec instead of relying on the impact tool. It does comes with a adaptor to fit the hex bits included for screwdriver and drilling bits but it would be too wobbly compare to a standard drill/driver with turn vice pinch for the drill bits. There is a working light which is great for working in the dark, a separate battery indicator with green LEDs and a button to choose 3 level of speed.

The AcDelco Cordless Impact Wrench arrived neatly packed in a printed cardboard box. In the set you get the main tool, a 20v battery, a battery charger, a 22mm Chrome Vanadium socket, a square-to-hex anvil adaptor, 8 hex drill bits and 6 hex driver bits. The battery is not compatible with any of the common big name tools and is only suitable for ACDelco tools. The impact wrench boasts a maximum torque of 340Nm and 2800 RPM, which paired with a brushless motor, makes the tool exceptionally efficient. The peak torque of 340Nm is impressive for a small tool and is perfect for heavy-duty tasks like removing car wheel nuts or tackling bigger DIY projects.

As an impact wrench this performs well but I wouldn't use it for anything else. I have other tools way better for driving and drilling. It's light and the construction is decent but why oh why are so many cordless power tools coming out with this naff barrel plug charging system. Fortunately I won't have to use this that often so it may last a while. At least while I'm restoring my old Wadkin Table saw.

The Cordless Impact Wrench is equipped with a high-torque motor that produces a powerful impact quickly and easily for a wide range of fastening and dismantling tasks. The cordless design allows users to work wherever they need to, without having to search for an electrical outlet or worry about power cord length limitations. The Cordless Impact Wrench features adjustable torque and speed settings that can be tailored to different job requirements. The product is also equipped with an LED work light that provides illumination in low-light environments to ensure accuracy and safety on the job. The Cordless Impact Wrench is ergonomically designed for a comfortable grip that reduces fatigue during prolonged use. High-quality materials and manufacturing processes make these tools durable and able to withstand frequent use and harsh work environments. Compared to traditional corded impact spanners, Cordless Impact Wrenches are more environmentally friendly as they often use rechargeable batteries as a power source, reducing energy consumption and carbon emissions. Although the battery life of the Cordless Impact Wrench is improving, it may still be low for long, intense use. Therefore, you need to ensure that the battery is fully charged before use and have a spare battery on hand.

Really nice budget impact drill comes with loads of attachments nice little battery and there’s a nice sort of size to fit in your toolbox

It's not a bad impact driver. Worked well on some 100mm screws. It definitely works well unfortunately due to not being able be to buy a replacement battery replacement as a spare

A really well made impact wrench from ACDelco. Supplied with a sensible section of tools, drill bits and drivers. You can add an adapter for use with normal hex head bits. Adjustable control via the little panel on the base. Comes with a battery and charger, but if like me you already have a selection of batteries from a famous brand (the blue ones - see photos) you wont need the included battery. Clear owners guide included too. This has already been a very useful tool with many uses...from removing wheel nuts, winding up caravan legs to installing TV brackets to brick walls. This does it all.

This impact wrench seems well made considering the fairly low competitive selling price. I was also surprised that my Makita LXT batteries also fitted it (cheaper and it wasn't mentioned in the description so as I already have a few 5Ah batteries I'm all sorted for more long term use.

For it's size this impact wrench packs a good punch and has some really good features, especially for the cost. You have the ability to change the speed electronically on the wrench and it also has a really useful auto-stop feature when loosening bolts to stop you spinning them off to far unintentionally - when the wrench detects the bolt has been released it stops the motor - this can be turned off and on as needed. It comes well packed with a range of accessories including battery and charger, a great addition to my tool set.

For a cordless impact wrench, this feels pretty light, but also very sturdy. I was also impressed with the size, it is actually quite compact when compared to others I have seen or used. I liked the extra features like the battery monitor and the LED work light, it just makes using it a little more convenient. The variable speed trigger and reverse are also useful, and it comes with a useful number of accessories, this includes the following items: 1 x 22mm Chrome Vanadium socket 1 x Square to hexagon anvil adaptor 8 x Hexagon drill bits, 6 x Hexagon driver bits 1 x Impact wrench 1 x 20 volt battery 1 x Battery charger 1 x User manual Overall, this is a good impact wrench and at £59.99 it seems reasonable value for money.

Mini monster for home use. Immediately made use of it to remove a stuck bolt in my gym. it did it well. It has a good function to remove the bolt then auto stop! Quite useful, just press the button on the settings section. The speed control is in the trigger but isn't very smooth. You can further cap and adjust the max speed using the button on the battery as well. The charger is supplied and directly charges the battery The supplied chucks fit easily and it comes with bits in a bag. Relatively light weight. Would be a game changer if it came with a belt clip, as it already had the hole on the side.

The item arrived on time, as described and packaged well. This is a great drill, not the highest price available on the market but that does not always mean great quality. This drill does everything you need, the added accessories are a bonus. The drill is easy to use and responds well. I believe the quality of the drill matches the price tag given.

Perfect for the handy man doing odd jobs, Drill and Impact driver with a good selection of bits for most light jobs around the home or work place. A very powerful tool and great battery life too. Great speed control from screwing in a screw and not over sinking it to driving a carriage bolt into a garden post. Powered by a 20v battery and good charging time too.

ACDelco is a well known American brand, that has existed since about 1900, however its not particularly well known in the UK, so I was interested to review this impact wrench and compare it to my 1/2 inch drive Makita. This is model ARI20132, which has zero information available on-line on the ACDelco web site. Only this listing on Amazon seems to show up. Similarly, going to the acdelco-tools web site and looking in the P20 series (as it has a 20V battery) doesn't show this model either. The side of the unit lists the manufacturer as Mobiletron Electronics Co. Ltd. Taiwan, there is also a 1 year limited warranty pamphlet in the pack listing the manufacturer as Mobiletron / Durofix and providing a UK supplier address in Preston. Contact details are also printed on the cardboard box the unit is supplied in. The box also says that the ACDelco brand is used under licence by Durofix and gives the same acdelco-tools link on a .co.uk domain. The packaging, supplied options and list price (£59.99 at the point of review) seems to clearly place this product at the budget end of the market. It comes in a plain cardboard box, so there is no plastic storage case to keep it in. By comparison my comparison Makita was £150 for the bare unit, no battery, charger or box and it has a broadly similar specification when I looked at both. The cardboard packaging states that the unit has a metal gearbox, which should be expected for something of this style, given the amount of force involved in breaking M10-M20 bolts loose. The ARI20132 has what can only be described as a significantly under-rated battery for a power tool, this one is supplied with a single AB2061L, which is rated at 18/20V, 1.5Ah, 27Wh. This is the smallest battery I've seen on any power tool (Even my battery vacuum cleaner came with 4 x 4Ah batteries.) There are no state of charge indicators on the battery and oddly, its charged via a 5.5mm/2.1mm barrel jack, this fits between the pins on the top of the battery. The manual says "For most jobs, a charge of one hour is adequate", this implies that the battery will not be fully charged in that time. Indeed, checking the basic wall wart charger that is supplied, it is only rated at 20V, 0.8A. This means that a flat battery will take around 2 hours to fully charge (1.5Ah battery capacity / 0.8A charger capability = 1.875 Hours minimum). There is an LED indicators on the charger unit, which is RED when charging and GREEN when charged. Mine took about 90 minutes to charge to GREEN. The manual also says that it will take 5-10 full charge / discharge cycles to reach full capacity (i.e. battery formatting) The battery has 3 terminals on it, a +, a - and one smaller pin, which is presumably for temperature sensing when used on a larger charger. The impact wrench only has two pins, so one for + and -, again indicating this as a lower end product. I note from the manufacturers web site that a fast charger is available for £25 (list £43) and larger 4Ah batteries are available for £40 (list £77), or 2Ah for 27.50 (list £47). It would be wise to get a second battery and a faster charger as nobody would want to wait an hour or more when working on their car. The faster charger is listed as being rated at 2A in the manual. The bottom of the unit has a red power looking button and several indicators. One set shows state of charge of the battery (30%, 60% and 100%). There is also a selection for speed giving High, Medium, Low and a Reverse Auto Stop indicator. The button does nothing when pressed and initially I was wondering if it was defective. Referring to the manual, to make this work, you must first squeeze the trigger on the unit and then the control panel comes alive for a short period of time. In the forward direction, you can select the required speed, High=2600rpm, Mid=2100rpm and Low=1800rpm. For reverse, the torque level is not selectable, only the Reverse Auto Stop can be toggled on and off. If on, when it breaks a bolt loose, it will stop, when its off, it just continues rotating, undoing the bolt. The speed of the unit can be controlled with the trigger on the body, as is common on many other power tools. The harder you squeeze, the faster it rotates. There is also a work light, which is again common on such tools. What is odd though is the statement in the manual (page 11), which states "Note : Continuous use of the variable speed range is not recommended. It may damage the switch and should be avoided." So, it seems that the manufacturer is saying that the design is poor / under rated. Again, comparing to other vendors and common use patterns, people expect to be able to use the controls on a device in a reliable manner, so this is particularly worrying. I guess that the veiled message is that the power transistor doing pulse-width modulation to vary the motor speed, will get very hot during partial squeezing of the trigger and will presumably let out the magic smoke when it overheats. In regard to the accessories provided with the unit, there are a puzzling collection of unexpected accessories. The obvious ones that would be expected are the 22mm black painted Chrome Vanadium impact socket, along with the usual fixing hole through it. This lines up with the similar one in the 1/2 inch drive sprocket on the main unit. There is also a clip and a metal pin so that the socket can be affixed to the impact driver, again in the common manner used by other equivalent products. Now things get a bit strange. All the other accessories are drill bits and screwdriver bits, which do not seem appropriate for such a power tool. There are 8 drills, 4 of which are brad point bits (wood drills) and 4 of which are standard drill bits, although they make no claims on their type (i.e. HSS, TIN, etc), they are sized 3mm, 4mm, 5mm and 6mm. All the drills have a hex mounting and are not just standard round twist drills. The drill bits are used via the provided "square-to-hex anvil adaptor". Drills are inserted into the hex end, the opposite end is the 1/2 square drive, again fixing using the pin and ring if required. Once installed, the drills are loose and can freely move back and forth in the holder, but not rotate. There are also 6 screwdriver bits, all of which state that they are Chrome Vanadium, the flat ones come in sizes of 4, 5 and 6. The cross head ones are PH1, PH2 and PH3 Philips variety. There are no Pozidrive bits provided, these too can move back and forth in the adapter. I would not expect to see drill bits provided with an impact driver, particularly one with a 1/2 inch drive as that states its 251 ft-lbs / 340nm torque capability. This can only result in broken drills. The small screwdriver heads fall into the same category of snapped small screws. Smaller impact drivers would have the screwdriver bits and a drill would have the drill bits, as implied by the name. So, I'm puzzled as to where this driver is being positioned. Is it for heavy duty car use as the form factor and manual implies - Page 6 says M10-M20 standard bolts or M10-M16 high tensile bolts, which implies a proper Ugga-Dugga Impact driver for stuck bolts, however the puny battery capacity doesn't seem to support this. The lack of any info for small bolts and screws in the manual, plus the requirement to use variable speed mode to make rotation controllable (which the manual says not to use), implies that this is an afterthought or attempt to make the machine usable on a broader set of situations. The lack of any packaging to keep the tools in also means that all the accessories are knocking into each other, so the drills will probably be dull once you receive them as they have been unprotected during shipping and if not, then shortly after you get them. I would prefer to see this product decide which part of the market its aiming for and to do that one job well. Remove the inappropriate accessories, spend the money instead on a better capacity battery and more tool-appropriate battery charging solution. As to bolt performance, I only had a selection of M10 / M14 bolts in my garage and none of these were stuck, unsurprisingly, the unit had no problems loosening and tightening them. At the weekend, I'll give it a go on some wheel bolts to see how it deals with them. This should be no problem as my equivalent spec Makita has no problems with those either. Given the price of approximately 1/3 the Makita for a broadly similar spec, its worth considering for home hobby type workloads. However, the small battery would need a spare and a better charger to make this more workable.
