How to Cut Small Holes in Glass

A mason jar with hole in the side.

Decorative mason jars make great gifts. You can fill them with a variety of objects and turn them into a light source. To accommodate an electrical source, you will need to cut a small hole near the bottom of the glass jar.

Things You'll Need

• Drill
• Diamond bits

Instructions

1. Outline a hole near the bottom of the jar. Position the hole on the flat side of the glass, rather than the bottom curve.

2. Turn on the sink for a low-pressure flow. Place the glass under the water where you plan on cutting the hole.

3. Drill slowly in the center of the marked circle. Make sure the water continuously flows over the glass as you drill. When the bit breaks through, stop and replace the drill bit with a larger bit.

4. Slowly drill the hole with the larger bit until it cuts through the glass. Stop and replace the bit with an even larger bit. Continue this process until the marked circle is completely cut out.

Tips & Warnings

• Paint a jar black, cut random holes in it and add a light source so the light comes through the holes.

• Drill slowly or the glass will break. Use caution when handling glass and power tools.
