Over the last few years, there have been quite a few changes to in-line circular saws. Manufacturers have made them lighter and more powerful, and have added many features. About a year ago, I tested eight in-line saws for an article in JLC (see "Wormdrive Saws," 2/04). Ridgid had just gotten into the power-tool business and did not have an in-line model for us to test. Later in the year, however, the company introduced the R3210, its first wormdrive saw and the tool my crew and I tested for this article. Ridgid did not skimp on features when it designed this saw. The R3210 has a 15-amp motor with oil-bathed gears, an aluminum base plate, and a magnesium housing and guard. The grip is overmolded rubber; the depth and bevel locks are oversized to make them more comfortable to use. The saw has a folding rafter hook and a 12-foot cord with a plug that lights up when the tool is live.
The first time my crew tested saws, we learned that certain tasks quickly separate the best models from the merely average ones. One such task is roof cutting. If the tool is good for that, then in my opinion it's good for everything else.
