Sorry – I may have asked this question or a similar one a while back. Someone suggested that I use an ordinary circular saw fitted with a carbide/diamond blade to cut a concrete wall away. I agreed, so I bought the blade, did some home jobs with it (that I just happened to also need the special blade), then I went outside today and cut a 2” x 8” slot in the concrete – no problem at all. I’ve already gotten my money’s worth out of the blade that cost less than $20.00 at Home Depot’s or Lowe’s (I forget how much).
Well, my question is, do they make saws with larger blades? I would like a saw with at least a 14” or 16” or larger blade so that I will be able to go downwards or upwards through the concrete. Even if it’s 20”, I can always set it to 8” depth which is perhaps a bit less than maximum.
If I have to stick with my 7 1/4” diameter blade – it will take a long time and I will always only be able to penetrate about 3” or so.
As it is, I do the sawing in multiple passes to save on heating – it’s not necessary, I just like to baby my nice saws that I have.
I’m willing to spend some money – not a thousand bucks though – and should I go used on this?
Here’s a pic so you can see what I’m doing – I want to cut slots for wood posts all the way through the concrete wall. It’s not really a huge job but perhaps a bit big for my little saw – that’s all. The work I’ve done only took 5 minutes.
Should I just rent a saw and buy my own blade or use their blade?
