Cut off saws are the bomb, That I do know. My instalations have started to bump up this year and eventually I know I'll need one. The thing is, I can't justify spending 800 dollars for one just yet. My question is, I've seen blades for circular saws and angle grinders, and I'm wondering if it would work for the time-being until I drop the dough. Has anyone used these tools for cutting pavers ?? I'm not doing patio installs, so the amount of cuts I make is minimal. My only concern is what the dust would do to my cheap circular saw, or my expensive angle grinder. The circular saw I can trash, thats no big deal.
