Great saw but not impressed with life span of Diablo blades. Know of any other brand blade to fit this saw for fiber cement siding?

Asked by: Anonymous
I have yet to find a different blade. I too am disappointed in the life of the blades. I have found that you have to keep the plunge cutting to a minimum. It kills the blades very quickly! If you avoid plunge cutting they do tend to last ALOT longer. I use mine almost specifically with fiber cement backer board for tile. Hardiebacker and siding absolutely eat these blades but competitors products tends to be a bit kinder to the blades.

8-Amp 5 in. Fiber Cement Circular Saw is rated 4.1 out of 5 by 49.
Rated 4 out of 5 by from 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.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from sweet This is the ticket for cutting plycem and other thick composite material the dust is keep to a minimal only dust not caught is as the blade exits the piece. If you put another piece in front of the board you won't have any dust. I also added pvc pipe to go to the bottom of bucket and added 3" of water this added weight to the bucket and hold the dust down, for cutting hardie siding use shears or a cutter like a paper cutter blades don't last this the best I have found to keep dust down I've been doing this for a long time

Rated 5 out of 5 by from Very solid design The blade supplied with this saw is good for 25 cuts then it starts creating red hot scorching and its LOUD. You can expect about 70% of dust to be collected, but that is a lot of dust considering the nature of fiber board. Once I put on a diamond blade the saw cut smooth and "quietly". This is a high quality, well designed tool, that works better than a simple shop vac set-up.

Rated 4 out of 5 by from durable Have had this saw for two plus years and have used it side 10+ houses with fiber cement. Keeps the dust to a minimum and takes any beating I give it. Two issues. First, I live in the Pacific Northwest and we work in wet weather. After about a year I noticed the dust wasn't collecting in the bucket. Had to take the saw apart and chip away hardened cement inside of the vacuum system, which is a pretty narrow channel through the back of the saw. Second, like many other posts is the blades. As with all fiber cement blades, if you don't cut quick and perfectly straight the blade heats up and the teeth are lost. Its easy to kill a blade on a 12 foot rip. I typically go through two blades per house, which is 40 bucks. Not sure if a depth adjustment would help since i'm only cutting through 3/8 material. (maybe I have three issues.) Still high regards for this tool.

Rated 4 out of 5 by from Does what it suppose to The bevel adjustment would not stay locked on the first one I bought, but Home Depot refunded with no problem. This saw certainly cuts down on dust when cutting fiber cement board. I changed to a diamond blade and it then worked well on cement roof tiles. I find it helpful to vacuum the inside of the bucket filter every now and then. The blade does not last too long, but what are ya gonna do with fiber cement? Be prepared to go through blades quickly. One of the first circular saw I have used where the guide line was accurate.

Rated 4 out of 5 by from 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

Rated 5 out of 5 by from great only cut a fe boards but it cuts down the dust a lot. i like it, i like it a lot. I did by the diamond blade to go with it after soe recomondations and it cut very nice. Having trouble getting the Lifetime warranty, that part of the system seems to work only if you are really determined and have lots of time ad patience to sit on the phone.
