Just checked the FAQ but would like to double check:

I need to drill an 8mm or so hole in a glazed ceramic floor tile (bog
screws).

Masonry drill on slow and some insulation tape to stop wander? Am I
correct... Might be near the tile edge...

Can't afford the f*ck up fairy visting here!

For starting in such materials I use some tape, then put the bit in a wheel
brace, hold the wheel (not tbe handle) and rock it so that the bit does
about a quarter-turn back and forth. It can't wander off as it never turns
enough. Also, with no noise from a motor, I can apply pressure until a
slight grinding noise is just visible, so I know that the bit is beginning
to bite but isn't going in too fast.
Out of curiosity I once put a 6mm tile bit through a wall tile by finger
power alone - not recommended but does show how good the correct bits are.
