Rated 4.3 out of 5 by 80 reviewers.
Rated 5.0 out of 5.0 by Great Performance Excellent powerful miter saw...I have had this 12" Compound Miter Saw for four years without problems.. I make rustic style furniture with different grades of wood. I like that the miter cuts go further than 45 degrees with clean cuts. Since I had this saw I have cut over three hundred hickory tree spalings between 3" to 5" in diam. these tree spalings are very hard wood, cutting with no problems. I also purchased the Ridged stand which is also very good quality. I give this machine a 10 with all honesty. If you are a woodworker and need a saw that won't give you problems this is the one at a great price also. November 24, 2014
Rated 4.0 out of 5.0 by Great Saw, One Flaw I bought this machine with the intentions of doing rough and finish carpentry. It works really well for both and does what you would expect it to. The one flaw is that the laser is very difficult to set to precision. I have had my saw for about 3 years now and still haven't fooled with it enough to get it right. Also, the belt chirps upon start up. The machine is 3 years old and runs fine but you cant really trust the metal angle angle adjustment either. It seems that when stored collapsed on the Ridgid cart, it may have tweaked something. I would recommend this however it isn't the most durable of the bunch November 24, 2014
Rated 5.0 out of 5.0 by Best compound miter saw I have ever owned. This compound miter saw has the brute force of a chain saw with the finess of a scroll saw. Everything I have thrown at it it cuts with absolute ease and control, from 6 x 6 timbers to 1/4 molding. The laser is accurate and the blade brake if very fast. The work clamp is especially handy when working solo. This beast is definitely worth having in your work shop. The life time warranty is just icing on the cake. December 12, 2014
Rated 4.0 out of 5.0 by This saw has performed flawlessly. It has been sometime now since I purchased my saw and I don't usually give reviews, but this saw has performed above my expectations. I've cut large timbers, intricate miter cuts and framed numerous projects with this saw. The dust collection could be improved on this saw but everything else performs great. I highly recommend the foldable table for this saw for ease of storage, mobility and the extendable arms for cutting long boards. November 24, 2014
Rated 5.0 out of 5.0 by Most accurate cutting saw I have ever used This miter saw cuts dead on 90 degree angles right on the money every time. Easy to adjust to any angle even compound angles. Easy to change saw blades.. Best saw, most accurate saw I have ever used. when selecting and moving from the preset miter angles the angles locks in smoothly and accurately every time. I highly recommend this saw, for any lever of user from home owner or professional ! Buy this saw ! November 24, 2014
