Drilling Holes in Glass by
Using a Drill Press
is part four of a multi-part tip on using a drill press to drill
holes in glass. Click here to go to part one.
The main steps, continued.
6. Once the container and glass is in place, lower the
drill press down to where it touches the glass where you'd like to
drill the hole. (Don't turn the press on yet.) Remember,
the glass must be just under the water in the container and resting
on the piece of wood or Ceramaguard.
7. After you've adjusted the piece so that it's
positioned to drill the hole in the correct spot, turn on the drill
press. From this point on it's important that the piece not be
allowed to move about in the container.
8. If you have a helper, have him or her hold the piece
firmly in place while you work the drill press. If you're
drilling by yourself, use one hand to hold the piece and the other
hand to operate the lever on the drill press.
9. Bring the drill bit down so that it just touches the
glass, then slowly increase the downward pressure on the glass.
The bit will start to drill into the glass. You'll probably
see some white areas in the water (those are glass particles that
are being drilled away).
10. Most drilling mishaps occur due to drilling
too fast. It's critical that you drill very slowly through the
glass, even letting up slightly to let the water clear then lowering
the drill bit again. It can take several minutes to
drill the hole.

Note: The process
described in the tip works best for items that are small enough to
fit in a shallow plastic container. Future tips will discuss
the necessary adjustments for drilling larger items.
