EWORK Cordless Impact Wrench 1/2 inch 21V Brushless High Torque Impact Gun Max 700 Ft-lbs Power Impact Wrenches with 4.0Ah Li-ion Battery, Fast Charger, 5 Sockets, Tool Bag (RB-810)

The media could not be loaded. What did I like about this beast of an impact tool? What's NOT to like?! I got it to handle some big old, rusted bolts on my truck that I cannot free up with a crescent wrench - I don't currently have any sockets big enough for the bolts so I gave this thing a go on the hard to free up lug nuts on my old 3/4 ton and as you can see in the video, I included that it goes thru them like candy. I'm anxiously now to get a big 3/4" drive socket set so that I can try this thing out on something tougher! Now, this is not a lightweight tool - you can literally FEEL the steel in this thing, its heavy! But for the intents and purposes of a tool like this I would be suspect of its quality if it were not heavy. I have another set of lighter use power tools from Ework and have been very impressed with them so when this became available I decided to give it a go as well since the batteries are interchangeable - I show a picture of one of the smaller tools and its battery in comparison to this big boy... and the battery packs DO interchange and you can switch them to each other as you please... the big 6AH battery that comes with this 3/4" impact might run the small one for days I guess. HAHA. Again, I am always impressed when a manufacturer cares about how their product arrives to you when shipped and they did not disappoint. You can see I took pictures of the inner box and the packing made sure everything arrived in good condition. The big battery has a little different "gauge" than the smaller capacity batteries and on the better side of things I thought - the LED's are big and bright and you can readily see how much juice you have left in your battery. The battery came about 2/3 full and it took about 45 minutes to fully charge from that state. I was very happy that they included a 3/4" to 1/2" adaptor as well since I could start to use it right away by using my 1/2" sockets. Still, to put this big thing through its paces I'm going to have to wait until I can get a 3/4" socket set. I'll update if I run into any capacity issues but from what I'm experiencing with this wrench already, I don't expect any issues at all with the equipment and vehicles I intend to us it on. We have a couple of old tractors with some pretty large nuts and bolts and some field equipment that tends to get rusty and tough to service at times... But I don't think you would be dissatisfied with this wrench if servicing heavy equipment and trucks. Hopefully I'll get a lifetime of service from this!

Works great

Si ya lo prove y funciona muy bien cumplió con mis expectativas

Indeed you are powerful, as this user had foreseen. Good work, Ework.There was no disturbance in the force of this RB-810 model as it removed the very stubborn cylinder cap from my old Craftsman 3.5-ton floor jack, using a 52mm socket I sourced from Amazon (SING F LTD; ASIN B01LY4R534).I'm rebuilding this jack and I wasted far too much time and effort in futile attempts to remove that cap, using everything from an 18" crescent wrench and hammering on its handle with a 4-lb. sledge, then using that wrench with cheater pipe (actually an old inner tie rod tool) to using my 24" GearWrench breaker bar (kit on Amazon: ASIN B08P25TX62) with that 52mm socket. No joy. Nothing would break it free, and I was putting tremendous amounts of torque on it.It had me practically pleading with it, "I feel the conflict within you. Let go of your hate for me."Wanting a cordless impact wrench anyway, I purchased this Ework 700 ft-lb model RB-810 and used it with the 52mm socket. The rebel cap was easily defeated and off in just a few seconds! You don't know the power of the Ework side.I also tried some lug nuts with the 19mm socket included in the kit and each nut was loose in about a second. Galactic level gratification right there.Reverse/break auto-stop works well to prevent spin off. There's no auto-stop in forward mode – this isn't a torque driver – and this model is powerful enough to strip threads if you aren't careful (I was, so it didn't).Not so fast, commander:The variable speed on this model is improperly implemented. It's very difficult to make fine adjustments. With a slight pull on the trigger, you get very slow speed. Pull just a tad more and you instantly get a big jump in speed. Pull a tad more and it's nearly full speed. A tad more again it's full speed. It's full speed through about the last half of trigger travel, no matter where you put the trigger in that span. Not good.I might have assumed the intent was to have a few set points for different speeds, rather than it being truly continuously variable, BUT... if you're very careful, you can get slightly different speeds at different points in trigger travel (over the first half of travel). Clearly, the intent was that it should be continuously (true) variable, so this is a hard fail in design or switch manufacturing.This may not be a deal-breaker for a lot of readers, but some might want to know how it works (or doesn't work) on this model.Speed is variable in both directions, except in auto-stop reverse mode, where it's full speed only.Brawn:This bad boy is heavy! Sure, it has a lot of plastic like everything else nowadays, but it doesn't feel cheap, yet the price is lower than competing brands with much less rated power. Build quality is good; there are no loose fasteners or anything else amiss on mine.I can't speak to its durability or longevity, as I haven't dropped it or otherwise abused it, and I haven't used it beyond what I've already described. I'll be doing a complete front end suspension rebuild soon, so If my wrench craps out prematurely, I'll update this review accordingly.Ework backs it up with a 1-year warranty.No brains (mode control design):The mode button is only available after you engage the trigger switch. No big deal, you say? Ok, how about this: pulling the trigger turns on the very bright work light LED, which blinds the user when looking at the control LEDs and trying to set mode/speed.When the work light LED is not illuminated, neither are the mode LEDs, and the control button is disabled, forcing the user to engage the trigger and get blinded by the work LED just to change settings. I have to cover the work light LED with my finger or thumb while changing speeds/modes with another finger/thumb. If you forget you have to cover it, you get blasted in the eyes like a camera flash went off in your face at close range.You get about 10 seconds before the work light goes out, which is enough time to change mode settings. But, it makes no sense that you cannot select mode/torque before engaging the trigger, when the work light LED isn't blinding you.It's annoying enough to make you want to force choke whoever is responsible for this idiotic design, and the cubicle "engineers" who obviously never used a power tool in their lives need to go back to flipping burgers or digging ditches.Driven:The included sockets seem decent quality. The finish is even and complete, there is no flashing around the pin holes, and the machining of the socket and drive pockets is good. The pin holes are properly centered. The internal walls have the typical radius corners and are machined flat.I would have preferred larger labeling – the font is tiny on the smaller sockets. The markings appear to be laser etched.Pin-up model:The kit comes with a pin and o-ring. The o-ring is sized right for the included 17mm socket, but it's a struggle getting it on the larger sockets in the kit. Ework should have included 2 sizes of o-ring.Large and in charge:The charger isn't anything out of the ordinary. It's nothing to write home about, but it does its job. The battery arrived with 1 bar on its built-in charge meter, and I haven't used the wrench long enough to run the battery down, so I can't yet report how long it takes to charge from completely empty, nor how long a full charge typically lasts.It's in the bag:The included soft bag is large enough to hold everything, which is how the kit arrives, and seems well made, but there are some things I'd change about it. It has 3 front pockets, with the middle one having a Velcro-type flap. However, the pockets aren't large enough to accommodate the charger, and there is no internal pouch to keep the charger separated from the wrench. That's begging to get things scratched up or otherwise damaged.The top is zippered and reinforced with a [presumably metal] bar surround, so it stays wide open while you dig around in the bag, which is a nice touch. The bottom is not similarly reinforced – it has a somewhat rigid liner, presumably plastic, that gives it some structural integrity.The feet are relatively hard and feature a number of pyramid gripper spikes on each foot. I guess this is meant to help keep it from sliding around on dirty or greasy surfaces. The feet seem like they could take a fair amount of abuse from dropping the loaded bag on a concrete floor, but how much abuse the wrench itself could take from doing this is anyone's guess (the bag bottom is not padded), and since there's no pouch to separate the charger from the tool, the likelihood of damage to either or both from such mishandling is increased (assuming you tend to keep your chargers and tools in their kit bags).The carrying handles have a Velcro-type strap to keep them bundled when desired.The bag is better than some I've seen, but I would have gladly paid a couple bucks more for a proper blow mold case.Verdict:The wrench has plenty of power to suit most users' needs, and the price is decent for what you get in the kit. I deducted a star because of the stupid mode control design. I should probably deduct another star because of the variable speed operation not being up to par, but the feature isn't that crucial for me with an impact wrench.

Works perfectly use it daily as a lube technician at a dealership and have only had one car that wouldn't break the lug nuts and even someone's snap on wouldn't either supervisor was impressed with the quality for the value

I have had this for more than a year. The batteries hold a charge for months and the torque from the gun is incredible. I own several trailers and I use this gun to remove wheel lugs instead of hooking up and air hose. I highly recommend it.

I don't normally write reviews but this is a great little find. Full featured with battery indicators torque indicator, work light, very compact and STRONG! Nice case and charger. I bought a larger set of SAE sockets to complement the metric sockets that come with it. Also bought a smaller set of 1/2" drive torqe limiters... which I consider mandatory since this little guy is so strong. Most car lug nuts torque specs range from about 75 to 140 ft/lbs. Overtightening past your specs could result in warped rotors or damaged wheel. For safety I recommend purchasing the torque limiting drive set. For example I use the 100 ft/lb limiter and then use a torque wrench to go to the 111 spec on my Scat Packs 6 piston Brembo brakes. I use the 120 for the rear specs and go from there to 130ft/lbs.I just used this to change blades on a 50" zero turn mower and it removed the bolts with ease. Used the 80ft/lb limiter to retighten to spec. I don't know how durable it is or how long it will last but I'm assuming this 520 ft/lb version should do well for home and shade tree mechanic work! Great value... Would recommend.

Decent set.
