        Q:What is the height of the drive head as compared to the �" ratchet, R866012? According to the specs, the head of the impact is negligibly taller than the ratchet, but it looks much bigger in the pictures. Also, is 3200 rpm the correct speed for this?
        by|Aug 7, 2023
        2 Answers
        Answer This Question

        A:  Yes the head height of the R8721 is much bigger than the R866012 by an inch. But no comparison to the nut busting torque. While the R8721 is a true impact as opposed to the R866012 which is a ratchet designed for lighter duty assembly jobs.

            Relatively lightweight and compact, delivers strong loosening and tightening torque
            Ridgid doesn’t disappoint with this 18V subcompact brushless right angle impact wrench. I have their regular impact wrench that I use around the house (e.g., installing tv mounts into studs), but it doesn’t give me great access or reach to work on the car. This is where the right angle impact wrench comes in. It has four different speed settings (3 speeds and auto tightening to prevent over tightening bolts) and produces 250 ft-lbs torque, sufficient to loosen many bolts under the hood (drain plugs during an oil change, removing the exhaust, changing the brake pads, alternator, etc.). You may not always need the impact function, and can use it gently for its reach only, while working on different-to-reach bolts. If you will have only one impact wrench, this one can do the job of a regular one as well. I am using it with a 4ah battery and the weight is not bad at all (3.5lbs with the battery). It has a variable speed trigger responding to how tightly you squeeze it. The breakaway torque is indeed strong; it easily loosens the wheel lug nuts on my car and can tighten them too. The nuts require 80 ft./lbs torque and it brought it to that when I tested with a torque wrench. I needed to make a very little movement (1-2 mm) before hearing the click. Overall, a great tool to have in your garage and when the need comes up, it can save the day!

            Great tool with a lot of power
            I’m actually really impressed with this right angle impact. I was removing the power steering from my truck, and it removed bolts with ease. It says it’s rated at 250 ft. lbs. and I definitely believe it, If not close. I even tested it on the lug nut of my truck and it removed it pretty easily. The tool itself is very well-made. It’s definitely not the lightest or most compact but it does the job. My favorite thing about it is the variable speed trigger because some bolts I worry about breaking them. It’s got four speeds, The 1-3 on speed And the last one is for auto tightening. That feature itself is really cool because once the bolt hit bottom, it stops. Stopping at prevent, breaking a bolt or damaging something. Really great feature. Another thing I really liked about it was the LED is in a pretty good spot to light up the work area. Especially under the hood when sometimes it’s hard to light up. Everything on it is really easy to use like the forward, reverse and lockout. Switching settings is really easy too. The one I got has the friction ring, and it works very good. I had no issues with sockets coming off or anything of the sort. It worked out really great in tight areas where a conventional impact won’t fit. The anvil on it it seems pretty tough, and all around the tool is built to last. The grip on it is also really nice and not tough on the hands at all. And that’s another Thing I noticed that the impacts aren’t jarring, but they are strong to remove. Whatever it is you’re doing. Definitely recommend to anybody

            Well designed!!
            At 250 ft/lbs of breakaway torque, this right angle impact wrench does a great job of getting into tight spaces or getting to those angled areas. The tool is extremely well balanced when loaded with a battery, making for extremely easy use. The tool features 3 speeds and also an auto tightening mode so that you can have greater control over the work you are doing. Also features an on board LED light. This tool gets the job done!!

            Fantastic Impact wrench
            This is a fantastic right angle impact wrench by Ridgid. The impact wrench is well made and feels like a high quality product. From the rubber overmodeling grip, to the smooth trigger to the metal cast anvil head, the whole things looks and feels like Ridgid put a ton effort into making a high quality product. This Impact also qualifies under Ridgid’s lifetime service agreement which is such a great bonus. You get a quality tool plus the backing of the company that they will repair it for as long as you own it at no cost to you. The wrench has 3 settings and then an auto setting. Very easy to switch your setting by a push of a button near the grip of the wrench. Your auto setting is about the middle of the rpms for the 1st setting and your second setting. You also get 250 ft lbs of breakaway torque. Finally the anvil is 1/2 inch with friction ring. Overall this is a very great impact wrench and with the backing of Ridgid’s lifetime agreement you can’t go wrong.

            So comfortable to work with.
            At first I thought this impact wrench might be too heavy. Weight is not a problem at all; it is not too heavy or bulky. I have no trouble using it for my personal automotive work and other chores that come up in my garage. The power is amazing; it breaks bolts loose when otherwise I would have to use a lot of time and elbow grease. Its compact, allowing me to get in small hard to reach spaces. I always appreciate a brushless tool because I've found them to last longer. I've never had a Ridgid tool disappoint and this one is another example of the quality tools they produce. Once again, I can say if you want a good tool buy a Ridgid.

            The best of both worlds for an impact wrench - a great reach and good power.
            Ridgid makes great products and has an outstanding 18V power tool line. The 18V subcompact brushless 1/2 inch right angle impact wrench is one of those tools you appreciate when working on automotive and farm equipment with had to reach nuts/bolts. The right angle reach allows an impact wrench in an area that a conventional impact wrench could not access. There are four settings for different speeds, ranging up to 3200/RPM on high with a maximum torque is 250ft/lbs. I have a variety of 18V batteries and felt the tool as well balanced with a 4 or 6Ah battery. The LED light comes in very handy by illuminating any fasteners upon light pressure of the trigger. I’m impressed.

            Awesome tool, love it.
            This tool is versatile. I love it for doing brake jobs. Gets behind the rotor to remove the caliper or caliper bracket with ease. Will easily remove lugs from most vehicles. If all you do is change brakes on your car this may be all you need. I still use my mid torque for my Silverado lugs but this will take them off. If you use locking lugs you will have to slide the key into a deep well socket and all impact wrenches lose considerable power when using adapters, extenders, etc.
