I got a diamond drill bit, cut the hole, then was going to do the v shape, but my cheap plasplugs cutter, the blades about 2 mill so it would have took 2 mill either side, and I found it chipped as the cut was ending, I did a practise bit, I hoped for a small piece that would just fir together, is that done on athinner blade, better cutter? also any tips for cutting the holes, I did practise, but its quitehard to start off were u want, on a 45 degree, I had to start the drill quite fast
