Rated 3 out of 5 by from Good for less precise work, difficult registration Have used the 10 inch dual bevel non-slider for about a year. Negative issues: Registration for both of my Ridgid products was a joke. The reply was something like "we can't find you in the data base so send us a bunch of paperwork and ..." I was able to register the sander eventually but not the miter saw. Also, I signed up for an account, and now it has disappeared. Lastly, the saw could not be aligned without filing the fence, and it will not hold a 90 degree setting -- ok for construction lumber but not for any precise project requiring multiple pieces. The positives: Cuts strong, seems solid, weight is just right for this old guy, and it stores nicely. I usually cut outside because of the dust, and the laser is good in cloudy weather only -- invisible in the sunlight.

Rated 1 out of 5 by from NO LASER!! Buyer beware... There is no laser! The website here and at Home Depot indicate otherwise.... including the in store demo. All state there’s a laser. There is only the shadow cast by the blade from the LED worklight. That was the only reason I bought this saw over the dewalt. Will likely return if not made right. Check out my pics. Otherwise I’m pleased with the saws performance.

Rated 5 out of 5 by from Good Price Good Saw Have been using the Ridgid compound miter saw for ten years now. The angle accuracy is still right on the mark. Had to replace the laser guide once and had the blade sharpened a couple of times but I use the heck out of it. Have built two houses for my personal use using this saw for cabinet construction, T&G ceiling plank panels, door headers, window headers, etc.. Would not hesitate to buy another one if the need arises and would recommend this saw to any serious DIYer or professional contractor.

Rated 4 out of 5 by from Quick and Easy I used this saw to cut our hardwood floors. It was easy to use and helped get the job done quickly. Very clean cut

Rated 5 out of 5 by from Solid and Accurate I have enjoyed using my miter saw, it is built solid with a cast frame and I find it to be very accurate. Also like the warranty that comes with it.

Rated 5 out of 5 by from excellent saw - very mobile I perform a lot of finish carpentry work and need a mobile miter saw for cutting casings, base and crown moldings. This saw is light weight and easy to cart around, is very precise and delivers excellent, clean cuts on hardwoods, pine, & MDF. On top of delivering excellent results, this miter saw was very in-expensive. It is a rugged work-horse.

How do you attach a ridgid shop vac to this

the end that plugs into the vac is the only piece that seems to fit, but then you are left with nothing to plug into the vac. Seems like you would have made the port the same size as the end of the hoses

Does the 4112 have a depth stop, e.g. for a dado?

Asked by: DarkSky
Thank you for contact RIDGID customer support. The miter saw does not accept dado blades.

Does the R4112 Mitre Saw have much of a kick when it starts up?

Asked by: 01keef
Depends on your definition -- I am an old guy, not very strong, and I find it easy to use without much of a kick.

Can this saw be used as a chop saw for metal?

Asked by: Patinasoul
Thank you for your interest in RIDGID. No, we cannot recommend the R4112 for use with cutting metal. It is not a metal cut off type saw. It is designed for the application of cutting wood and plastic materials. Regards, RIDGID
