Rated 4.1 out of 5 by 50 reviewers.
Rated 5.0 out of 5.0 by best dust free cutting small light weight saw, easy to get in tight areas. Dust free operation, and able to cut other materials,ie tile and cement by changing blades. March 14, 2014
Rated 4.0 out of 5.0 by Using the RIDGE Fiber Cement Circular Saw The saw vacuum system did contain 75-80% of the airborne cement dust while cross cutting and ripping with the tool. Would be better if the blade housing would allow viewing of the blade to make scribe cutting more accurate when vewing the tool from left of the blade. Should be sold with an option to purchase a durable soft case to contain and store all the accessories. Also the shoe should be adjustable so the blade doesn't cut deep into sacrificial supporting wood on work surface. December 12, 2013
Rated 5.0 out of 5.0 by Best cement and granite saw ever ! I've done a number of siding jobs with this saw and the dust vacum system is great. Just tried using it with a 4 inch dry diamond blade to cut 1/2 granite countertop and it also worked great. cut down stone dust also. August 26, 2012
Rated 4.0 out of 5.0 by promising saw the saw worked extremely well contained 95% of cemnt dust my problem was tool broke on 2nd day of usage liked it anyway and purchased 2nd tool June 9, 2015
Rated 4.0 out of 5.0 by good purchase These are great little saws for cutting fiber cement. They are good for containing the dust. They are easy to use. The two biggest downfalls are there are no diamond blades just carbide tipped. The other is the bearings in the rear of saw burn out very quickly. We bought three saws last year have only one still working. So the overall durability for the cost is my only complaint December 24, 2014
Rated 4.0 out of 5.0 by Great saw (with a couple of notes) This unit is great. It cuts well and does what it says in collecting a lot of dust (in fact most of the dust is collected). It cuts straight and is light so very little fatigue. The hose length is adequate. The negatives are the blade is small so it dulls quickly. The supplied blade dulled after only doing half a house with Hardie board.however after putting on a frued blade the saw kept going well For 4 houses with a lot of cuts and rips Of the Cement Board. One other thing is the noise level. It is very loud. Ear muffs are necessary don't cut without them It will leave with a ringing That is worse than a nagging partner. Get the saw, put on ear protection, cut upwind... and you'll be very happy. March 25, 2015
Rated 4.0 out of 5.0 by If you like dust, you won't like this saw! Halfway through my job, but i am liking this saw. Really minimizes dust. It is light and easy to use. April 28, 2015
Rated 5.0 out of 5.0 by Saved time and effort! My wife and I are using 1/2 inch concrete Hardiboard to lay porcelain tile over about 1100 sq feet in our home. Prior to getting the saw, we were scoring the concrete boards multiple times and snapping them for cuts. For small openings such as vents we had to score an "X" over the area and use a hammer to break the board. All of these techniques are very difficult and time consuming when using 1/2 inch concrete boards. Also this technique left less than desirable results sometimes. From the moment we got the saw, all of the headaches disappeared. This little saw cut through these boards cleanly and quickly. Cut outs are a breeze. Setting the saw up is quick and easy. What would have taken us a day or more to do now only takes a few hours. The dust collection feature is nice. It captures about 85-90% of the dust. This is the best 169.00 I've spent on a tool in a long time! If you are doing a job with this type of material you need this saw! April 6, 2015
