Re: cutting glass
I purchased my drills from Sears and Lows hardware stores. Other
hardware stores sell them as well. Tungston Carbide Spear Point, for
drilling Glass, Mirrors, Tile and Ceramics.
All you need is a hand drill with variable speed and some practice
and patience. Cover the surface with water and keep it wet. Don't try
to push the drill through the glass. Use the cutting edge to grind
away the material. Don't expect to drill 100% without a lot of
practice, you will break a few. Drill just through to the other side
and turn the piece over and finish through the other side.
For large thick glass, I use a dam of modelers clay to keep the water
in the hole while I drill. Slow and steady does it. don't try to
force it and don't use the highest speed the drill will go. I have
been successful up to 1/2 inch.
2" circles are possible with a suction cup and a jig to hold the
glass cutter. See for example "Mission Impossible". It does work but
needs a new glass cutter. The secret is to tap the score on the other
side of the glass and get a clean crack through. You will need some
good sand paper to smooth the edges. Watch the dust, not good to
