Managed to cut a dozen 10mm diam holes in 7mm thick Brazillian slate without too much difficulty. Obviiusly glad the diamond coating on the saw rim did not wear off!
Only trouble was, that without a traditional arbour bit the hole saw would “walk” off & around the work piece surface on initial contact with it. That makes precise positioning difficult. I found you have to first to try and get an edge of the hole saw rim to dig in to the work piece in order to locate the hole saw in the place you want to drill the hole. Once that’s done you can proceed to engage the hole saw rim full square on the work piece and complete drilling the hole.
