Answer: 
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.

Answer: 
It's worth noting that the instruction manual DOES NOT recommend use of "cut off" discs (only grinding, sanding, polishing and brushes) -- it's very explicit in mentioning that cut off discs should not be used. It's not clear why -- this may just be a CYA situation.

Your asking about the warranty, i understand it only applies to the battery's that come with the tool itself,...i can tell you however that getting that warranty is a pain in the butt......i have not had to use it yet....but i have to think that with it being so difficult to get, what will it be like having to get something fixed r replaced.

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.

This works on all the 18v Ridgid batteries. I recommend the 4.0Ah batteries, since the 2.5Ah batteries will die much quicker.

Thank you for your interest in RIDGID!
All RIDGID 18V platform tools and batteries are interchangeable. However, the RIDGID 18V Lithium Ion batteries do require their correct charger.

I have an R86040. It quit running. The right light in front of the power button will come on if the tool is turned on when I plug in a battery. That is the only response I get to anything I've tried in attempting to get this tool to work. Very disappointed so far. This grinder has maybe 20 minutes of gentle use since I've owned it. I usually use a corded grinder. This is just used for quick light jobs. And it's already junk.

Rated 3.9 out of 5 by 57 reviewers.
Rated 2.0 out of 5.0 by Not impressed.....at all I have almost all of the ridgid cordless tools, well a bunch of them anyway, not to mention several corded rigid tools. I have always been more than impressed with all of there tools to say the least. That was until I bought this 18V grinder. Even with the 4.0 big battery in it, it lacks any kind of power for cutting, even w a thin disk, or grinding. I worked for Black and Decker / Dewalt for years. This is worse than anything that they ever put out by far. I hate to leave negative feedback about anything, especially RIDGID tools, but this grinder is terrible. Sorry guys, you missed the boat on this one. September 3, 2016
Rated 1.0 out of 5.0 by Money waste This is the first rigid tool that I'm not happy with. It kills the battery in minutes and shuts down if you use any pressure. Buy a corded grinder September 6, 2016
Rated 5.0 out of 5.0 by Denzil Wilson Great grinder batteries last a long time good for home projects August 9, 2016
Rated 5.0 out of 5.0 by Works great This grinder works great! Battery holds up well while using! July 14, 2016
Rated 1.0 out of 5.0 by Great for cutting soft butter Was excited to try my new Rigid cordless grinder since someone walked off with my Dewalt grinder. Had some other Rigid tools that worked well so I figured this would be too. Wrong!!! This was a toy compared to my old 18v Dewalt. Does it cut? Maybe some soft butter but certainly not steel. I used it to cut 3/8 bolts that secure handles on shipping containers we sell and the dreaded overload lights flash as soon as the disc touches the bolt. Soon after the thing craps out. I returned it to Home Depot and got a Dewalt. Problem Solved. Do not buy this tool! May 19, 2016
Rated 1.0 out of 5.0 by lsa their warranty registration is sucks I have 6 ridged tools and 6 batteries try to register them in their LSA never got approve don't get fooled. I go back to dewalt better tools. May 7, 2016
Rated 5.0 out of 5.0 by great purchase for my shop I am really pleased with battery and overall of machine. May 31, 2016
Rated 3.0 out of 5.0 by I like the tool... hate the trigger. I have owned this tool for a little over a month. It was bought for the purpose of cutting 1/8 inch metal plates, chain link fence, grout, tile and all kind of other things. It does shut down if you use too much force but if you pace yourself it cuts fine. The thumb trigger can be difficult to use after an exhausting day. It does eat batteries so plan on getting a pack of 4.0 amp batteries. Overall I'm satisfied and it has definitely become my go to tool. June 21, 2016
