I am using a 1/2" tile bit. I plan to use the drill presses slowest
speed. I have a friend who used the same type bit without coolant and
had no breakage. The piece of gass is small enough to be manageable.
I could put it in the fide or freezer to cool it down prior to
drilling. I am going to try the first hole with the piece at room
temp and see what happens...
wish me luck...
Agreed, in fact, I'd suspect cooling the glass first would be a _very_ bad
idea. It's not so much the heat from drilling, but more the temperature
difference in different areas of the glass. Cooling the rest of it will make
that difference much greater.
Now, maybe if you heated the glass first...
Nahh, the heat generated by the drilling will cause a rise above any ambient
temperature that you have. Just go slowly and follow their advice.
