I've got a vague idea there's a way of reviving diamond tools that have glazed and lost their bite. If the grit has gone you can't do anything. A quick internet search might help, if you're curious.

I have a set, made up of sizes I needed - so sort of random - from 10mm to 40mm diam of tungsten tipped hole saws. I use them on HT steel.... ....you can extend to 30mm if you drill from both sides.
Very good, but the OP has 3mm diameter screws, less than hull thickness!
