Outstanding Saw
Rating: 5
I have many Bosch tools. I had 3 other saws prior to this. Best saw I ever used. Using a Freud 100 tooth blade for straight and miter cuts. I use a thick kerf blade for bevel cuts. Amazing results! The saw tracks without a hitch. Dust collection is great. This was money well spent.

Awesome Saw
Rating: 5
I was rebuilding my deck and needed a new mitre saw to replace my old 10" mitre saw. I did my research and am glad I chose the Bosch GCM12SD. Very well made, very detail oriented. Nice features overall. Impressed with how the slide mechanism works as compared to the other models out there. My only issue is the saw is a little heavy but that is to be expected with a saw of this quality. This saw should last me for a while!

My new favorite tool
Rating: 5
I bought this about a month ago to tackle a wainscot project at home which had 8"+ wide baseboards. I quickly recognized/appreciated the thoughtfulness of the design and quality of construction. Miter and bevel adjustments are precise and intuitive. The dual axis mechanical arm movement is very smooth - great design and execution. When connected to my vacuum, the dust removal was pretty effective. Cuts were clean and precise. Overall, very impressed with this product!!

Excellent Engineeering
Rating: 5
I don't often feel compelled to write a review. That said, this saw and the team who developed this say deserve praise. I don't like to make public my great “stupid” mements, but ego aside, I dropped this saw from 4 feet above the ground on concrete. I was sick to my stomach. Minutes later when I plugged it in, relief swept over me as I began testing the saw. All cuts remained plumb and square. All bevels and angles were precise. The slide srill pulled smooth as silk and true. Lastly, the sound of a motor running with precision and ample power remained pitch perfect. Thanks guys, for saving me from myself and from what, with any other brand compound sliding miter saw, would have been hours of readjustments or a whopping repair bill. Need I say more?

Excellent saw
Rating: 5
This saw is a solid machine. The axial glide system is a perfect and very precise design. There is no side to side play like other saws. The saw cuts are perfect. I was amazed at how perfectly all the adjustments were right out of box. It was perfectly square to fence and base. All the controls for bevel and miter are right up front and easy to set. Saw is on heavy side but I have it setup on the Bosch T4B gravity rise saw stand. This stand folds easily and makes it convenient to move around. The saw easily hooks up to my vac system and when connected collects dust perfectly. Saw has lots of power and is quieter then most saws I have used before. Overall I am glad I bought this Bosch saw and stand. It will work perfectly in the woodshop and with stand easily taken out on jobs.

Great saw , terrible hand grip and trigger.
Rating: 4
I bought my second 12” Bosch mitre saw because the first one I bought almost 9 years ago has been amazing. Gets used all the time by employees carpentry framing and finish work. Tough as nails. I was expecting the new saw to be the exact same but they had to mess with it , have made the hand and safety on the trigger terribly awkward. Still a great saw just not as good as it used to be

Decent saw...should be nicer for the money
Rating: 4
I've dreamed about this saw for years. For what it cost, this saw should be twice as nice. It's super heavy, has no carrying handle on top, dust goes everywhere even when hooked to a vacuum. Saw is quite difficult to get square as well. For as much as these things cost and they don't include a light or laser either. Kinda silly. But it's a neat saw.

Does what they say
Rating: 4
Had the saw just over two weeks and have few complaints. It's done everything you said it can do and I'm happy with the purchase. I only wish that somehow it were lighter and easier to transport and move. It matches well with the folding miter saw stand.

Horrible changes
Rating: 2
Just picked up a new saw yesterday, the new design of the handle and saftey switch is awful. The grip is to thick, the sliding switch is in a god awful position. Not to mention the downgrades from the lever locks for the fences to needing to tighten down the little screw if you want to move them. The product design team truly screwed the pooch on this one, will be looking into swapping in a properly designed old handke with dual side safety buttons but if that's not going to work It's getting boxed back up and promptly returned.

I would swear by it
Rating: 5
Power tools: you either swear BY them or swear AT them. This is one I would swear by, despite those who swear at the blade wobble. More on that later. Having had mixed experience with Ridgid (I swear by my TS3650 table saw, but swore at my now discontinued 14 inch band saw) I was actually looking at a competitor's product when I saw the R4221 had greater specs at a lower sale price. I am very happy with it. Movements are smooth and fluid without drag or binding, making precise setting very easy. The head is well balanced so it doesn't flop to one side when setting bevels. The instruction manual is clear and well written (yes, I'm one of "those guys" who reads manuals) making assembly relatives quick and painless. The preset detents are crisp, solid, and tight, making the standard cuts easy to obtain. The miter detents were off by a fraction of a degree, but I was able to adjust it to true without much trouble. Coupled with the MSUV cart and a self made measuring cutoff table, and this a valuable addition to my shop. Now about that notorious blade wobble. I read the reviews after I made the purchase (I normally do a lot of research before buying) and I was alarmed by the number of people that had problems with wobble. It doesn't seem to matter if it is the R4221 or R4222 or the specific serial number, the problem seems to be random. I hope Ridgid can get the issue resolved, otherwise they've killed a terrific product. I make furniture and regularly need to cut 5/4 by 12+ inch by 8-12 foot red oak boards sometimes with a 83 degree bevel. This has been time consuming and sometimes dangerous with hand held saws or the table saw. It is a lot quicker and easier with the miter saw. Even setting the bevel is easy with the help of a digital angle finder. So far cuts have been very smooth and clean, with nominal tear out, even after I seriously dulled the included blade cutting some U channel that I only thought was aluminum. I'm sure that I after I get a new vibration free blade the cuts will be almost polished. A couple of minor issues. The blade brake pulls the saw downward when it is engaged. Not a problem when making through cuts. However, when making stopped cuts in vertically held boards, it will cause tremendous over cutting. The solutions is to carefully lift the saw out of the cut before releasing the trigger (which Ridgid strongly discourages) or to use the depth stop. I haven't used the depth stop yet, but it looks like it would take three hands to set it correctly. Also, when the brake first engages, the entire head torques slightly clockwise. When cutting boards wider than 6 inches, this results in a barely perceptible groove in the left hand piece from the side of the teeth cutting into the board. (see second and third photo) The groove can definitely be felt, but is virtually invisible when boards are joined. The LED sighting takes a little getting use to, but it is precisely accurate. I would definite recommend this saw with the caveat that you should be prepared to switch to another one if you get a bad one. Ridgid, do us woodworkers and yourself a favor and get that blade wobble under control.

Fantastic Miter Saw with Class Leading Capabilities
Rating: 5
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.

Greatest addition to my arsenal!
Rating: 5
First off, I read all of the reviews on this site and other sites to determine if I was making the right decision purchasing this saw. I saw everything that everyone had to say about the "Blade Wobble" and whatnot. So, I knew what to look for as far as the serial numbers when I went into my local Home Depot. The particular saw that I got started with a "1804", so I wasn't too concerned. I got it home, unboxed it and begin to verify if it were square and whatnot. It was pretty dead on! Pairs perfectly with my Ridgid Table Saw.

Great saw and it cuts like a boss!
Rating: 4
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.

Blade wobble still an issue
Rating: 3
I knew what I was getting in to with a known performance issue concerning the blade wobble, however, this saw really had everything I need. After seeing multiple posts that the blade wobble was fixed after certain a serial number sequence, I felt somewhat comfortable in buying it. Well, my SN is 1852 and I can assure you the blade wobble is still there. Darn thing cuts anything I throw up there with ease. Most of what I do is rough work, so precision isn't a priority for me. However, the wobble is very noticeable and does impact the squareness of cuts. Will be sending it in for a warranty claim. We'll see how many I have to cycle through before they make it right.

Not a square cut among them
Rating: 2
I bought this saw because all of the other Ridgid power tools I purchased have been awesome. After I setup the saw I performed my first cut. For an unknown and reoccurring reason, the blade cuts straight about two-thirds of the way across a piece off wood, then it appears the blade shifts and the cut takes a small angle change. The result is a cut that isn't square. Doesn't matter what type of wood, how thick, sliding or down motion, etc. I kept around an old Delta mitre saw and have used my father's DeWalt sliding mitre and never had this issue. I'm severely disappointed, especially after having read that Ridgid had resolved the issue.

Wobble - not what I expected from this brand
Rating: 2
I bought this saw based on price and brand quality compared to others out there. When I set up the saw and put the blade on, the saw had significant more wobble than I expected. I took the blade off and reviewed the set up per the instructions and still had the same issue. I did buy a red blade, but did not switch it out yet. Any suggestion on anything I can do to adjust it or am I stuck with a wobble on the saw?

Had to return it cause the blade had a bad wobble after only a few times using the saw . Was going to exchange it for a new one but after reading a lot of reviews and seeing that this is a very common thing I decided to just return and buy a different brand .

Blade wabble
Rating: 1
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
