RIDGID R4210 Out of the Box
Right out of the box the first thing I look for on any miter saw is the fit, finish, and most importantly the accuracy. I started off by checking the squareness of the fence to the blade. The saw was ever so slightly out of square when checking with a machinist square. Adjusting the miter gauge was an easy process and the directions in the users manual were easy to follow. The entire process only took five minutes and now the saw is dialed in nicely.
Assembly is very simple with only the blade and dust bag needing to be attached. The miter saw comes with a stock RIDGID blade that most users will want to replace at least if you’re doing any finish work.
One of the things that stands out most to me about this saw is the fit and finish of the table and fence. The machined parts are flat movement is easy and smooth.
Lateral Head Deflection
When I first mentioned this saw on our Social Media channels several readers asked how this saw compared to the recently released 12″ version and more specifically lateral head deflection. While I don’t think lateral head deflection is that big of a deal if you’re using the saw correctly, apparently it’s an issue many guys are worried about (I myself think much of that can be controlled by being careful about applying lateral pressure on the tool during cuts).
I decided to do a simple test and compare the lateral head deflection of this saw to my Bosch 12″ glide saw in the wood shop. The 12″ glide is my go-to shop saw and I’ve had great luck with it and use it for all my wood working projects. For both saws I extended the saw out to it’s furthest position, applied a lateral load, and measured the head deflection using a gauge.
The Ridgid saw had approximately 1/32″ of an inch later deflection and the Bosch had approximately 1/16″ of an inch. Let me say I didn’t use any sort of measured lateral load. I simply pushed against the saws as evenly as I could. So please take these results for what they are, just a quick and dirty comparison, but there’s clearly a difference between the two saws.
RIDGID R4210 Performance
For me, a good miter saw is one that produces accurate cuts and offers easy to use controls. In addition, I’m interested in well built tools that will withstand the punishment that daily jobsite use demands.
After a quick adjustment of the miter gauge the saw was very accurate with miter cuts and cross cutting. I really like the blade shadow line compared to using miter saws with a laser. The shadow really allows users to visualize the kerf for more accurate cuts.
Like most miter saws we evaluate the dust collection system isn’t all that great. While the long dust shroud is a good attempt it’s still not that effective. I’d saw with the dust bag attached it picks up about 30-40% of the dust. When my shop dust collection system attached to it the dust collection improves just over 50% or so. Hopefully one of the tool companies figures out a really effective system for miter saws i the near future.
Overall Impression Ridgid R4210 10″ Miter Saw
10″ sliding compound miter saws offer users a more portable solution for jobsite projects compared to heavier, larger 12″ saws. Typically the slightly reduced cutting capacity is a fair compromise for a saw that’s easier to move around. The Ridgid R4210 10″ Dual Bevel Sliding Compound Miter Saw is an excellent option for contractors and DIY’ers looking for a versatile, quality saw at an amazing low price. Weighing under 50 lbs this saw offers everything users are looking for including a shadow cut line and the ability to miter out to 70 degrees both left and right! Throw in Ridgid’s Lifetime Service Agreement and it’s hard to ignore the value of this saw at just $349! If you’re in the market for a new 10″ miter saw this one should be on your list to consider.

I own this Saw’s big brother (the R4221) 12″ sliding compound version and have loved it so far. I installed an 80 tooth Diablo blade and the cuts are smooth and clean. Got it on sale for under $300.00 and purchased Ridgid’s wonderful rolling stand to go with it! If this had been available I probably would have gotten this on since the 12″ is probably bigger than I need.
I have this saw. Its shortcoming isn’t run-out but slight play in the detent when not locked. Its to bad,its ALMOST an first class saw.
I agree!! I don’t believe that would not come up in the reviews I watched before I bought it. I wonder if all of this model has the same problem
I would love to buy one of these R 4210 saws but can’t locate one anywhere !!! Can you help me ? Even concidering a good used one at this point !
Unfortunately they sell some models for awhile then release something different. Probably won’t find a new one.
