Rated 4.1 out of 5 by 53 reviewers.
Rated 4 out of 5 by Great Saw… Bad dust collection I got my saw about a week ago. It has been everything I wanted and more. It has planty of power and changing angles couldnt be easier. However, the dust collection system doesnt really work at all. The shavings simply fly right under the shoot. What little dust that does make it into the bag just falls out when you take the bag off because the dust sits right at the opening. My shop became very dirty very quick. I would inly recommend this saw if it is for outdoor use or you have a vaccum system. June 15, 2014
Rated 3 out of 5 by Back fence is not straight I purchased a 12 inch Ridgid miter saw and even though I spent $399 on the saw,it is almost useless due to the back fence being bowed. The bow is in at the blade and out at both ends which causes all angled cuts to be off and not mate to opposite cuts. January 18, 2014
Rated 3 out of 5 by Big Disappointment Laser is hard to see. Table lock and unlock is awkward to operate. Add the cost of a good blade to the cost of this tool before you buy. The blade is cheap and wobbles. September 6, 2013
Rated 5 out of 5 by Solid Recently purchased this saw on sale for $250. I was suprised how light it was but it's solid when in use. The extension to the base is ok but I don't find it neccesary. Same applies to the clamp. Both are made well. The blade spins up quick and the electric brake stops the blade in a few seconds or less. The cutting arm locks down for easy transportation. I love how easy it's to adjust the cutting angles. If I have any complaint it's the lazer. On mine the lazer is blocked by the blade before it can calibrated adequately. I'd rather have no lazer than a lazer that's 1/2 cm off. Not much of a problem since you can gauge the cuts by the cut plate. Even at full price this mitre saw would've been a good deal. July 7, 2010
Rated 4 out of 5 by Purchase of Ridgid 12" Compound Mitre Saw It was one of my son's birthdays and the other two sons and myself decided to buy him a mitre saw for his birthday and split the cost. (We also all plan on using it ourselfs) After visting the local Home Depots and looking at the Home Depot web site, we realized it was cheaper (by $100) to order this saw from the web site than just walk in and pick it up in the store. The end result was we missed giving him his gift on his birthday because we had to wait for shipping from Ontario but he's happy and says it works very well. Next time we'll start a product search sooner. May 13, 2011
