I have a old skill 7 1/4 inch worm drive saw, 30 + years old, and have had it serviced by skill once, I do normal routine maintenance and have had to replace power cords a couple of times. I also have a couple of regular circular saws by they are pretty much relagated to the storage bin.. Hmmm don't actually know when I did use them last.. Anyhow I don't have anything bad to say about the Skill worm drive saw, well unless you want to say it's heavier than the others. I also have a Portercable 4'' worm drive saw but do have a few complaints about it.. 1. No carbide blades for it, (at least that I've found). 2. The shoe is not as solid as it should be so adjustments are not very stable. 3. Why did they make it "left handed????" I just had to adapt!
