angle grinder blade for cutting marco rock.

[fishmonkey]

saw a few posts of people saying you can cut marco rock with an angle grinder with a diamond blade on it.

just wondering if anyone has experience cutting marco rock with a turbo blade or segmented rim blade.

Any blade will work some are better than others. But yea a segmented diamond blade is best. turbo blade, rim blade same same. The none segmented will not cut as well as the segmented ones.

I used a reciprocating saw with 12in or greater bi metal blades. I think the angle grinder will work, but my pieces were quite large so the longer blade made things more straightforward. You can always use a cold chisel to make the pieces smaller too. The flat cuts are great for the foundation of the structure. It makes for a very stable base.

Didn’t know you could use a sawzall. I might try that first.

I used 6 tpi. Have some water handy or better yet running water to keep the blade cool and clean when cutting.
