your add says you can count on free batteries, free parts and free service for the entire life of your tool. however your website says only batteries that come in kits qualify for replacement this grinder is sold only as bare tool which is it??? the 2 kits I have bought only have 1.5 hour battery so if I buy 3 hour it would not be covered?? if I an wrong please send a letter to verify
Asked by: Nick
I have owned Ridgid cordless tools for 11 yrs now and have used the free battery replacement and repair at least 10 times with the 7 tools I own. In fact, when a drill I bought in 2006 could not be repaired in 2014, they sent me a brand new drill kit, 2 batteries, charger - I was very surprised and pleased. It is a bit of a hassle to travel 2 towns over to drop off dead batteries or to leave a tool for replacement, but since I have several drills and corded saws to use in the meantime, it works out fine. Love the fact that I have 6 batteries that are interchangeable with each other and all under lifetime warranty. (yes, they all came in tool/battery/charger kits) I appreciate that they offer the tool only as I don't need any more batteries or chargers. I am a professional remodeling contractor.

Will the cordless grinder accept the 5/8" hole cut off discs?

Asked by: Tom
Yes. Recessed wheels are best, but I have used flat discs as well (contrary to literature with the machine). It might take threaded arbor disks as well, but I have not tried any.

Compatible Battery

Are the batteries contained in the R9200 combo kit (two - R84087 4.0 Ah batteries) compatible with the R86040B cordless grinder? They are not listed under the features section of the grinder.
Asked by: gh8toes
This works on all the 18v Ridgid batteries. I recommend the 4.0Ah batteries, since the 2.5Ah batteries will die much quicker.

I misplayed my key could I get another key

Asked by: Bobby
If you contact ridgid tools they will send you a new one for a nominal fee. Great tools, except for the grinder.

Customer Reviews

18-Volt Cordless 4-1/2 in. Angle Grinder (Tool Only) is rated 3.8 out of 5 by 72.
Rated 5 out of 5 by from 18V angle grinder Run time on the 18V 3AH X-4 lithium-ion battery is quite good. The soft start is excellent. With the battery installed the balance, grip, and weight are comfortable. I only have two complaints. Ridgid neglected to include their infamous nylon tool bag..They include a bag with the corded model! I had to spend an additional $26.00 through E-replacement parts for a storage bag! Also the spanner wrench is cheaply made. The one with this grinder is stamped out of steel and not the quality like the one that comes with the corded model. This will never replace a corded grinder for serious grinding, but for the times you are not close to an outlet this grinder will not let you down. Make sure you register this tool for the LSA program! I strongly suggest you mail in the registration with a signature required and registered mail..this will give you a paper trail should warranty documentation issues occur. AZman in Arizona

Rated 1 out of 5 by from the built in protections keep this tool from doing real work This tool will suck a newly charged battery down so hard and so fast ,that it will cut out and you have to wait for it to reset itself, 5 or 6 times cutting of a piece of 1 inch by 1/4 inch flat bar,which took 7 or 8 minutes. I have 4 batteries , 2 large and 2 small and it does it with all of them. My large drill, reciprocating saw, circular saw will do the same thing if you are working them hard. The grinder is useless for what it is intended , which is cutting or grinding in areas at heights or where corded tools are unwieldy. it is definitely not going to wear out , ever, because you couldn't do enough real work with it to harm it. It is easy to warranty for life if you engineer protections into them that won't let the tool work hard.. I have a dozen rigid cordless tools and I am going to switch to Dewalt ,Milwaukee , or Makita in the near future.. If you make your living with your tools, be warned

Rated 5 out of 5 by from best cordless grinder ive used I've been remodeling and building homes for the past 12 years. I've used cordless grinders by makita, dewalt, ryobi, and bosch and would have to say this one the most powerful and well built one I've owned and used. I bought a ridgid 5 pc. 18 volt combo kit about 4 1/2 years ago and it has held up very well to the daily use, love every peice in that kit, and am very happy ridgid finally added a cordless grinder to their line up, something I've been waiting for since first being impressed with my my 5 pc. kit but then bummed to find out no grinder available to go with the kit and 7 batteries i purchased. It has now come out and I'm very happy to have it, and have given my bosch away to a co-worker who is also happy for the free grinder : ). and is now much less hassle for me to deal with a mix matched kit of ridgid and bosch tools+batteries.

Rated 4 out of 5 by from Very nice for a small project. I would buy this again. Received this about two weeks ago. I have used it several times on different items. This grinder will replace my air cut off grinder. Can not see starting up the compressor when this is just a battery snapping in, away from working. It okay as far as power goes, not what you would get from a 120v grinder. I would not recommend it for a large project unless you have a good number of batteries (Goes through a freshly charged 3 amp 18v battery in about 8 to 10 minutes). The cost is fairly high. but it should wash out when you take the LSA into account. It is really to early to give a opinion on durability. I would buy this again.

Rated 1 out of 5 by from A rare Ridgid disappointment I bought this tool this week to use on a job site where 110v power would have been unavailable. Needed to cut off 3/8" bolts flush with concrete...not a big deal. And yes, even though the tool came with the grinding wheel, I bought several thin cut-off wheels for this work. From the very first cut, with a full charge on my Li 4ah, 18v battery, this tool immediately flashed its overheat warning lights. Even when I backed off and applied less pressure, the tool was not up top the task. It would shut down and need a brief coming off period before I could resume. And this was a fresh out of the box tool! Very time-consuming and frustrating. My son had his much older Ryobi cordless grinder with a new Li battery and it worked like a champ. I'm not a big Ryobi fan and I won't abandon my Ridgid cordless set, but Ridgid really needs to go back to the drawing board on this one. I paid $99 for it and with its severe limitations it's not worth a fraction of that price. I'm taking it back. I hope they can improve this model soon!

Rated 2 out of 5 by from Grinder returned Built pretty sturdy, but poor switch. Went through more than 1 battery cutting one 3/4 rigid conduit. It shut down 3 or 4 times. If you absolutely needed cordless I guess this may work in a pinch. I have other Ridgid 18v tools that I use on almost a daily basis, but this one isn't worth a $100 to me.

Rated 5 out of 5 by from Good grinder to have Grinder starts slow, must be so as not to kick out overload. After that it works great. Is not super powerful, and will not replace your corded grinder, but great for the small quick jobs. Also has a locking trigger, which is a nice touch. As powerful as any of the other cordless grinders out there.
