Ridgid Fiber Cement Saw Review

Ridgid Model R3401 5″ Fiber Cement Saw with AirGuard Technology

Over the last 6 months we’ve been testing the Ridgid 5″ Fiber Cement Saw with AirGuard Technology on a commercial building project. The project including installing roughly 10,000 sq. feet of fiber cement panel siding. The project required very detailed cuts around windows, doors, and flashing details. The following is my review of this fiber cement saw.

How The R3401 Performed

The crew has been using this saw for 6 months and it’s still working great. We’ve literally cut hundreds of feet of fiber cement with it and never had a single problem. Once again the folks at Ridgid have designed and manufactured a really tough, powerful tool that’s built to withstand the rigors of commercial construction.

Prior to using this saw we’ve always used circular saws with all kinds of different blade types for cutting fiber cement. The results were always the same; extremely dusty operation and a costly affair with all the blades we used up. I’m happy to report that those days are over now that we’ve been using the Ridgid R3401 Fiber Cement Saw.

Not only does the saw cut through fiber cement wonderfully but it cured both of the previous issues we were having while cutting cement siding.

First of all the AirGuard technology works really well. In a nutshell the saw has fans built into it that help push the dust through the dust collection hose and into a 5 gallon bucket. Basically this means that there is no need for a vacuum in order to collect the dust. Ridgid claims a 90% collection rate which I had no way of proving but I’d say it’s at least 75% or more. The bottom line is the dust collection system works quite well.

By using smaller 5″ blades the saw seems to be able to cut the material more efficiently and create less wear and tear on the blades (compared to when we used to cut with 7-1/4″ blades on a circular saw). We’ve only used two blades on the entire project which I thought was really great.

Final Thoughts

If you cut fiber cement siding for a living I highly recommend you check this saw out. It’s very powerful, easy to use, accurate and best of all helps significantly reduce harmful cement dust. Priced at just $169 I think it’s a great value. You can buy this saw from The Home Depot in a store or Online Here

    I used this saw when put fiber cement siding on my own house. Worked great. The only thing I wish it had was the non-marring composite shoe like the 6 1/2″ Ridgid framing saw. I just covered the shoe with painters tape.

    1. Todd Fratzel

      That’s an interesting idea. I have a feeling the thought is most cement products are painted afterwards. Although there are lots of pre-finished products on the market now.

      1. Jeff Williams

        Yeah we were using the Color Plus pre-painted stuff from James Hardie. They wanted to get some exposure so it was donated.

        I’m sure the metal shoe wears better than a composite would. Did you notice any visible wear after going through that much material?

        1. Todd Fratzel

          Not at all, the saw still runs like new. We cut all kinds of material with it.

    I am looking for replacement parts. In particular the connector from the machine to the vacuum attachment.
