Hi again,
I want to cut a hole for a new window in my house. It's got fairly standard cavity walls, built of concrete blocks. Actually the blocks are somewhat n on-standard as they have foam insulation inside them (I mean inside the act ual blocks - not inside the wall's cavity.) The only masonry-cutting tool I own is a 9" angle grinder. This will cut concrete blocks no problem, but o nly to about 3" deep. I suppose could hire a 300mm grinder for about £
28 a day plus the cost of the cutting disk which I'm guessing won't be at a ll cheap.Rotary grinders in general make an insane amount of dust. Is there any othe r tool that anyone can recommend? (I'm visualising something like a very la rge jig-saw with a diamond blade...)
Thanks for any tips you can offer,
JD
