I've seen the 7 1/2" blades for a circular saw in stores for cutting Hardie or cement boards but I'm interested in changing out the 10" blade on my table saw. Anyone ever done this?
You mean 7 1/4"? I haven't seen any 7 1/2", but that doesn't mean that they aren't out there. I did notice that the 7 1/4" hardie board blades only had four teeth, so I would maybe look for the lowest tooth 10" blade for your saw. The ones I found online were a little pricey, so unless I HAD
to cut the hardie board on a table saw, I think I would stick to the lesser expensive circular saw blades.
