Questions & Answers


Can this R4520 table saw be operated at home (i.e., residential) or more for commercial? I read some contractor table saws require more voltage than a residential home has. I have a newer house built in 1998 and I believe I have enough power.

Asked by Big Kahuna Phil September 8, 2020

I'm a USA trained Electrical Engineer. The R4520 is rated for 13 amps operation; therefore, it will run on USA residential power. That said, since a USA residential 120V circuit is typically limited to 15 amps, you should not run another item on the same circuit at the same time (e.g. a shop vac or dust collection system). So if you intend to have a dedicated area where you will use the saw, it is commonly recommended that is have a dedicated circuit.

Looking to replace the fence assembly with a longer one to accommodate bigger material. Any suggestions?Or is there to extend the existing stock fence?

Asked by JDG1 April 13, 2020

Best fence I've ever used is the Incra LS fence. But pricey, but works on any saw and is ridiculously accurate and repeatable

Why was discontinued this model table saw??

Asked by Nico April 7, 2020

It’s underpowered. Many times mine doesn’t have enough power to cut all the way. I have to back the board off, let it get more power and start again. I’d like to get rid of mine.

Is this belt driven or direct motor table saw?

Asked by jv April 3, 2020


what is the difference between the rigid 451`2 and 4520 table saw

Asked by burgwt01 March 10, 2020

a search of the literature indicates that the difference is the electric motor. Both are rated at 13 amp. The R4520 has a air cooled induction motor where the R4512 has a conventional armature electric motor. The size and all other features appear to be the same.

any issues with the alignment of the rip fence?

Asked by bob March 8, 2020

Hi Bob. There should not be any issues with the alignment of the fence. If you have an issue please call our customer service for help. 866-539-1710. Thanks for asking. Greg

Has anybody upgraded the factory fence and rails and interested in selling the old ones?

Asked by Redcloud March 4, 2020

I have seen a few guys that upgraded to some pretty fancy Incra Fence & Rails. They are pretty pricey and the set-up on this saw is very good As-Is. I can't see spending more than you paid for the saw, to upgrade a very good fence.

Is a solid table available for the RH side of the saw? If so, how much is it?

Asked by Joe March 1, 2020

Several years ago I made a wooden table saw table extension (plans were in the owners manual) that works fine). Also at that time I saw a metal table extension that would fit, I believe it was on the ereplacement parts website. Good luck.

Where can I see it on display?

Asked by Kenjamin February 29, 2020

I have never have seen it on display in any of the stores I have visited.

Why Clifton in store over charging $100 for item that is advertised 649 and they have item in stock

Asked by Adel February 24, 2020

Its a bait and switch. That home depot will not price match home depot online is rediculous. SO do this. Buy the one online and wait two weeks for it to arrive. Once it does check it out and if their are issues, return it for an exchange in the store. Rinse and repeat until you get a good one or give up. If you do not have the means to transport something this big and heavy back and forth to the store, then do NOT but this saw

What’s everyone complaining about??
I had this for all but five years now. Seems like everyone is looking for things to complain about. I had a small alignment problem at first but it remedied easily. Use your squares to line things up. It took four years for me to have to re align the right side extension table but I use my saw for everything since my basement shop is small. I glue and clamp on it, hammer things on it and varnish things on it, it’s a tool. The guide numbers on the left side are drastically off, I never replaced it, why? Because I own this thing called a tape measure! Three things I didn’t like: 1- as mentioned, the measuring scale on the left side was out. 2- the screws that hold all the plates together on the stand were rusty but, they sent me new screws, problem solved 3- the dust chute was on the very bottom, problem was easily solved, I made a wooden brace with a gate on it, much easier to take the hose on and off since I have to share it with other tools. I’ll add a picture. All in all I find this table saw a really good buy, once it’s lined up it’s great for everything I used it for and the wheels are a huge plus since I have to move it around to play musical tools, basements too small for everything I have. As expected, it’s very heavy so you’ll need help to load it, unload it and to turn it over once you get it put together. Hope this help, good luck with yours Use the directions to line up the motor, and the rip fence (fence can be a bugger). One other thing, wax the top and the rip fence to make everything slide along easily.

Good beginner saw, has some problems
I bought this saw march 2020. It took me roughly 6 hours to assemble, tune, and troubleshoot before I made any cuts. I think its a good hybrid between a proper cabinet saw and a jobsite saw. Lets start with the bad: 1. Before I even started assembly or pulled the main unit out of the box the miter angle adjustment screw rod was bent noticeably. 2. The table extension wings are thin press folded steel and are a small pain in the rear to align square during final assembly. The surface of these wings is slightly concave on one and noticeably concave on the other. This is from the machine bending process and is unavoidable with the thin metal used. Replacing these with custom hardwood or thicker steel will be the first modifications I'm doing. 3. The measuring tape on the fence guide was massively out of alignment on the left and a full quarter inch off on the left. 4. The plastic feet on the legs just seemed inadequate, but the wheels make that less of a problem. 5. I dont know if I've got the wrong nut handle on it or what, but the saw height adjustment wheel nut keeps coming off when spinnin that wheel. 6. The saw blade that came with the unit was absolutely garbage. Out the box it was relatively dull and bent by a 32nd of an inch. burned out on cuts and kept grabbing the wood with the side of the blade and pushed back. not kickback, pushed. It wasnt unexpected, but it was disappointing for the price of the tablesaw. replaced it with a cheapo irwin 24t saw and it cuts like buttah. 7. This is a biggie for me, as a novice woodworker. The throatplate has issues, major ones. The two biggest are that it does not sit flush with the table. its a 16th or more lower than the cast iron surface. Any peice I run through this I have to remember that untill I throw this plate in the garbo. The set screws do not fit flush, at all, and are not hardend steel. I kinked the phillips out of one with a thumb and forefinger tightening it. The second big issue came at the back of the plate, in the picture. If you barely tighten the rear screws, the tension between them torques the corner of the plate uowards. tight enough it will rise above the surface of the table. The Good: This thing is a really good beginner table for the price. Its mobile, sturdy, with a well designed dust collector. 1. Assembly, I had this thing fully assembled in about 3 hours. I was able to do it solo but I wouldn't recommend that cause this thing is HEAVY. 80% of the weight us in one assembly. It took me another 3 hours of fine tuning and reading to get it up to snuff and ready to use because reasons. 2. The castor leg assembly. I was expecting some rinky dink parts here because this is a prime place to save some bucks. Nope, this is as solid as you can get. i firmly believe the stamped steel legs will crumple before this assembly does. it rolls with barely a shove and dosent need too much force to deploy. bravo. 3. The fence and guide assembly. Tbolt slots across the entire bottom, nice touch. a solid steel brace on the long side and tbolt slots on both sides of the fence. this thing was engineered for jigs for days. 4. The dust collection chute, with a 6 inch opening from the factory. very nice, but needs adapter for shop vacs. I do like that its intended for a bigger system from the get go. 5. The cast iron top. Perfectly level, nicely cast and came with plenty of machine oil preservatives on it. Not a spot of rust. 6. The LSA. I brought up all the issues above about the bent screw rod and the misaligned measure to Ridgid. The parts people talked to me for nearly an hour, and had the measure stickers ordered on the spot. They told me what will break with the screw drive and found a repair place nearby. Ridgid told me no problem, we can get it fixed now or when it eventually breaks at no cost. There was zero judgement or questioning on their end and it was hands down some of the best customer service ive received in a very long time. I will be calling about a solution to the throat plate but I dont think they have one for it and I plan on making my own inserts reguardless. All in all, This is a very nice saw for the money and will last you until you reach a level of experience that youre ready for a true cabinet saw. With some minor modifications I think this saw will easily last me in what i need out of it for the next 20 years. New out the box its about 300 bucks cheaper than most used cabinet saws that would outclass it. After talking with Ridgid about their LSA this tool cant really be beat and i will likely have this saw for life or untill i need something more powerful that costs 2 grand. Even then ill probably jerp this saw around. Images are Throar plate torquing Throat plate below table what the ridgid factory sawblade did.

out of square
this table saw has plenty of power it is very well built except for the rip fence and the wheels the rip fence will not stay in square when I put the song all together. I had to adjust the blade in relationship to the miter gauge slot it was completely out of square and unacceptable after getting this suggested I tried for 3 hours to adjust the rip fence which came with stripped screws and a very big dent in the back of the rip fence either way I could not get it straight. the wheels only have 1 swivel caster and two stationary casters which makes it a little more difficult to move than the old wheel system that rigid used to make I know I've had both this is my second Ridgid table saw and this one by far has more power I like the enclosed motor and the dust port the sauce that's just a little bit higher than the old one. I'm going to have to remove the entire rip fence and the rails and replace them with something that will work better another added $250 to $300 depending on what I decide I think Ridgid could make a better rip fence but they probably won't. straight out of the box I believe this song would be all right if you're not too concerned about a square rip fence it has plenty of power with the three and a half horse motor. I believe the next saw I buy will not be a Ridgid for the money I think they better

Had this saw for about a year now and over all I am pretty happy. For what I do, it works 97% of the time. My previous saw was my dads old craftsman and while it cut fit, I hated the ridges on the top and it being so light. Push to hard you could push it over. Absolutely love the cast iron table! It's so smooth, it's a joy. I also keep it waxed, so it's always slippery. Can't saw to much about the fence, as I replaced it pretty quickly with a Incra LS positioner. But from what I remember it was a very nice fence. Much better than what usually comes with a saw out of the box. The fence also has t-tracks which is nice for jigs and stops. The mobile base is not bad, but it was a little tippy. I put mine on a cart I made and I can move the whole set up as I want. I also like that it is standard size, so I could fit a router table on each side. The miter gauge is surprisingly heavy duty. I can't say how accurate it is as I use an Incra miter gauge for real precision. Though I do use the included gauge often to push stock. Do like the push stick that comes with it, use it all the time. Extra nice it comes with a magnet. The only negative I can think of is that it is under powered. As I said, it works for most of what I do, but on rare occasion it's not powerful enough. For example, we are remodeling our kitchen and it had trouble cutting through 1-1/2" birch butcherblock counter. My Makita cordless saw cut the tops better than this saw. One other thing, sure wish it came with some kind of dust collection. The guard that comes with it is nice, but there is no way to hook up anything to suck up the waste. I ended up getting a Sharkguard and it works well. Over all I am happy with my purchase. A heck of a lot better than what I was using before. Plus it's hard to find a saw this size for the price. I know I locked before I bought this one. Though it has gone up quite a bit. Just don't expect it to cut everything.

I was a little hesitant to buy this saw based on some of the negative reviews, but I figured I had about a 90% chance of getting a good saw on the the first try. It also had a much larger motor than the delta table saw. Turns out I got a great saw. The table top is flat, maybe a thousands or so off in the center, but not enough to make a noticeable difference cutting. I always make my own adjustments to any saw I get, and it was easy enough to square the blade and heal to the table. My only complaint was the blade bevel indicated scale was placed in the wrong position making it impossible to align to both 0° and 45°. I peeled the scale of and placed it in the correct spot. I feel for the price I paid that should not be something that needs fixing straight from the factory. Overall it cuts great, even with the blade it comes with. Ive re-sawed nearly a 100 linear ft of 3" red oak so far (2 passes) and had no bogging down or burn marks. And rewiring the saw to 220v was very easy as well.

I have had this saw for 3 years, so this review could help you decide. Likes - 1. Is powerful enough for homeowner needs and is quiet for a table saw 2. Mobile base is great, must have 3. Weight - is sturdy, doesn't vibrate. 4. Dust collection is pretty good. 5. Riving knife and blade guard are really good. 6. Switch is nice. Dislikes - 1. The Fence is horrible ( see picture I upgraded to a Delta T3 and that fence has issues too(fence faces are concave??) so I added an aluminum extrusion side, result = awesome accuracy. 2. Flimsy sheet metal attachments ( I replaced one with custom add on). 3 Throat plate tabs are too shallow making it hard to make a zero clearance insert. I opted to buy a dado throat plate and add a piece of mdf to make that a zero clearance insert. Its works ok and wont break on me. 4. My right miter slot is not parallel with the left (not a deal breaker, I align everything based on the left slot. 5. The turning wheels are just ok, good enough. Conclusion - factor in the cost to add a new fence down the road if you want accuracy and safety, maybe build your own fence to reduce the cost (ibuildit.ca has plans - no affiliation I am just a fan). I would buy it again, but if I had the cash buy a SS.

After 6 months of research, saving and shopping around, I took the plunge and finally ordered my beautiful Ridgid Cast Iron Table Saw. Picking it up was a major pain, and lugging it back to my house required the help of my father in law. I almost died while wheeling it down our backyard hill, but it finally made it into the house and my soon-to-be workshop. Upon opening up the package, I was delighted. All the parts are incredibly well built, with a rock solid base and tabletop. I put it 80% together and time came to check the surfaces of the cast iron top & wings. Everything looked great until I tested it over the throat plate. It's unacceptably off-level and far from flat. I prayed that somehow putting the front and back rails would help pursuade the rock solid cast iron into shape (haha) and of course it didn't. The rails were indeed true and level, but upon tightening it to the front of the cast iron top, a large gap formed between the two. Once fastened, the two piece rail system split apart. I went ahead and did some test cuts anyways... thinking it may not make a huge impact. I did 5 consecutive cuts, and all 5 got stuck between the blade & fence, resulting in a violent kickback. Unacceptable for a $650 Table Saw, but this is Ridgid we're talking about... with their famous LSA. I called up customer support, hoping that they would stand behind their product and send out a replacement top. The product took 3+ hours to put together and requires at least 2 people to pick up a half assembled body... let alone move the entire unit. I don't own a truck and I don't want to injure myself. The agent was incredibly rude and quick tempered. He offered zero sympathy, and coldly reiterated "You have two options: Bring it in to a service shop OR exchange it at Home Depot." I am so disheartened. I looked forward to owning this product for SO long, with countless home improvement projects and furniture planned. I own many Ridgid tools and have always had good luck with them. I have no idea what to do --- ideally, I'd love to go back and get a replacement for the same model. However, the odds are that I'll end up with another lemon from the same batch. I sent Ridgid an e-mail and am posting this in hope that someone will step up and make this situation right. TLDR: This is a roll of the dice... an extremely heavy and inconvenient one at that. Don't expect much from Ridgid's customer service.

I had my doubts right from the start after opening the box that this might have been a returned item. The packaging and some of the items had finger prints all over them and the styrofoam looked damaged in the center of the box and not on the outside where you think damage would occur. The parts though looked to be undamaged and went together as expected until I started to adjust the extentions to the table top. As you can see by the pictures below the cast iron table is completely unflat so unflat that my cheap hard plastic job site saw is the flatest tool I have in my shop now. I'm going to finsh setting it up as best as I can and see how it cuts but I've never owned a cast iron table saw that is out of flatness this much especially from the start.
