Anyone have any tips for drilling holes in live rock tp put frag plugs in? Or putting frag plugs in live rock in general other than finding an existing crevice?

I'm assuming you want something you can use over and over. I like the idea.

I have never done it for frag plugs but have drilled lots of dry/live rock for supports etc.

Just use a masonry bit the size of the frag plug stem or a little larger (probably 1/4" or 3/8").

Go slow and use water. Don't put a lot of pressure on the bit. Let it do the work. To much pressure will sometimes fracture the rock..
