How can I safely cut small limestone bricks?
Something like this https://www.harborfreight.com/4-12-in-turbo-wet-dry-masonry-diamond-blade-68878.html and good angle grinder, at least 7.00 amp and dig about 1/4” all 4 side and little tap with small hammer would do the job. You have to rest brick (one being cut) on two bricks on the edge.
