12 in. Dual Bevel Sliding Miter Saw is rated 2.8 out of 5 by 17.

Rated 5 out of 5 by OldDominionDIYer from Fantastic Miter Saw with Class Leading Capabilities First of all I recognize I was fortunate that my saw does not exhibit any of the "blade wobble" others speak of. I have a higher serial number unit that has had very little issues compared to the earlier lower serial number model. Mine worked flawlessly after assembly and I couldn't be happier! RIDGID really built a fantastic unit in this Model R4221 12 inch Miter Saw. They designed a compound sliding miter saw that cuts 70 degrees in both directions, has the best type of kerf shadow LED marking system, blade brake, great ergonomics in a solid platform. If your looking for small and portable this is not your saw, but if you can handle the size and weight it will likely be the last miter saw you will ever buy. I have yet to use all the features but all my cuts thus far have been spot on. I did purchase the crown molding jigs and a second clamp so I won't have to keep moving the one that is provided from side to side. I am completely satisfied with this purchase, and will recommend this to my friends and family. By the way I am a DIYer, not using it professionally, although I think it would be a stellar performer for most professionals.

Rated 5 out of 5 by keeso from Wobble has been fixed! I spoke to a Ridged tech who indicated that saws with SN 1730 or later have had their arbors replaced to fix the wobble issue. I went to 2 different Home Depots and found one with a 1731 SN. I set it up today and can say with confidence that there is absolutely no wobble. The saw is fantastic and cuts smoothly with a smooth startup as well. The blade was set up at the factory dead on without need for adjustment. My only complaint is that the tall fences, when tightened, don't line up with the lower fence. They seem to be 90 degrees, but not flush with the lower fence; probably a 16th of an inch. Outside of that it is a bargain at $299.

Rated 3 out of 5 by mhkpilot from Just doesn't seem precise I'm just a DIY guy, not a contractor, not a builder, not a carpenter. I read all the reviews and decided to roll the dice on this saw when it went on sale due to the price, and the versatility this saw offers. Granted, it's HUGE, and takes up a pretty big footprint in my garage, but again, it was on sale and I figured what the heck. For starters, this saw's serial number is 1726, so above/newer than the 1725s the other reviewer was referring to. And I oiled both the inner and outer washers on the arbor like the instructions stated. After putting it together per the instructions and before turning it on for the first time, I used a framing square to check for the wobble and there was none. It was completely true to square. I then ran it for a few seconds (didn't cut anything) and experienced a very noticeable vibration (almost a shaking) in the entire unit when I moved the slider back and forth. I then checked for square again and it was out; it had a very slight wobble to where 1/2 the blade teeth touched the square and gave me a "ping" and the other half did not. Note: The distance between the half that touches and the half that does not is almost immeasurable; it is so small that I can't even see the space between the blade and the square when they're not touching. I then made several cuts on a 2x4 and it seemed to work ok, though I again felt the vibration/shaking and it didn't feel solid and precise, despite this thing's weight and mass. For my needs as just a guy who does projects around the house, this saw will suit me fine, and perhaps it's a little overkill considering it's size, power and weight, but I'd rather have it and not need it than need it and not have it. I gave it a rating of 3 stars because I'm an average guy who will use this saw for average stuff around the house and can deal with the tiny amount of wobble I've experienced but I would not recommend it given all of the wobble issues this saw seems to have, even if it's on sale...it's not worth the roll of the dice I thought it was. Due to the size and work it would take taking it apart and putting it back in the box and hauling it back to the HD to return, I decided to hold onto it given the wobble on my saw is so small. I gave it a "Fair" rating on performance since the wobble became apparent after it's first use (not poor since the wobble is almost insignificant on my saw), "Good" for ease of use because of how easy it is to move the saw to it's different cutting positions, and "poor" for durability due, again, to the wobble that exists after it's first start up. I would not recommend this to a contractor or professional due to the fact that my saw DOES have wobble out of the box (although minute), and the vibration/shaking I experienced isn't something I would expect from a high-end contractor's precision instrument (which this is supposed to be). I am a little concerned that my machine's tiny little wobble will grow into something more significant, and if that does happen I will take advantage of Rigid's lifetime warrantee (I just registered the saw) and have it replaced. If I had to do it all over again I would probably opt for the yellow or green saw and not have to worry about it.

Rated 4 out of 5 by SpongeBob from Good saw some blade wobble Just purchased yesterday. Does have some blade wobble. Called CS and reported the issue. They said they are aware of the problem and are sending me out a kit that is supposed to fix the problem. I read the wobble reviews on this site but did not see anything about Ridgid sending out kits for repair. I will update after I install the kit and change to 5 star rating if it resolves the issue. Other than the wobble, the saw is fantastic.

Rated 1 out of 5 by shiltzy00 from Blade Wobble I bought this because it's a great machine with everything I could ever want in a miter saw. I've been reading about the blade wobble for over a year now and have seen many positive reviews without this defect lately so I figured they addressed the issue. I set it up and it has the wobble!! I called CS and they said to return it and look at the serial number. first two letters are worthless but the next four numbers should be 1725 and above so I'm assuming there are just still bad units out there but the issue has been addressed and updated units are out there. why wouldn't they recall the bad ones and get them off the shelf. It's one store, Home Depot. I'm not a happy fella but understand that defects happen. So I will go find a unit that has that serial number, set it up, and if it's still an issue I will be forced to bring it and the stand back and "cough cough" buy the dewalt DWS780. free stand included with it right now. I hope it truly is fixed. This is my first Rigid power tool and may be the last if it's not fixed. If it is fixed, I will change my rating to the appropriate place. I got this saw for 350 in store. online is saying 499. I wonder if the updated units are going to be 499?

Rated 4 out of 5 by bskoreyko from Great saw and it cuts like a boss! I did not have the wobble issue so many people have mentioned. Perhaps Ridgid fixed the issue or it was just a bad batch. It is also possible that people missed the step about adding oil to the outer blade washer. FYI there are two blade washers (inner and outer), the manual clearly states to remove the outer blade washer and place a drop of oil on it. After oiling the outer blade washer, you replace the outer washer and re-assemble the saw (more details in the manual). I bought this saw for home use and love it! This saw is likely overkill for the projects I have but I bought the saw hoping to have it for a lifetime. I would recommend this saw to anyone looking for a superior quality saw loaded with excellent features. The other huge bonus is that the saw comes with a limited life time service warranty. The LED cut line is not a "laser guide" LED thus it can be hard or near impossible to see the cut line when cutting outdoors in the sun. Overall, I give the Ridgid R4221 4 out of 5 stars because I haven't it long enough to say it's a long lasting, reliable product. When I bought my Ridgid R4221 there was a Father's Day promotion so I also received a free Ridgid MSUV (AC9946) Mitre Saw Stand. The saw and stand are usually sold separately.

Rated 1 out of 5 by Gcpitt from Blade wabble Got this saw today was so excited to have another ridgit miter saw for my crew to work with, all the options on the saw were what convinced me to purchase the saw, got back home set it up and as soon as I ran it I noticed that the blade was wobbling way too much, I set my 90 degree square and gently turn the blade by hand to check the reason and I tell you what after marking the blade on zero turned it around and the blade was almost 1/8" away from my square. I have many ridgit tools that I am very happy with but this one is not!! going back to return it tomorrow

Rated 5 out of 5 by Duece49 from Work horse Located this saw at my local Home Depot on sale. Picked it up and got it home for set up. Easy set up, great features. Not sure what the blade wobble talk is, mine works perfect, no issues. I did have an issue with the LSA and am currently waiting for a response.
