When you've been out at the beach for part of the day, you may want to keep some of the shells you find and make them into a craft project. For some projects, you might need to make a hole in the shell, but shells are made of a fairly fragile material. With some care, however, you can drill a hole in a shell without cracking it.
- Skill level:
- Moderately Easy
Things you need
- Masking tape
- Drill or grinding tool
- Small bit or grinding tip
- Bowl of water
Place masking tape on the shell over the area you intend to drill through. Place the tape on both sides. The tape helps hold the shell together despite being drilled through.
Attach the small bit or grinding tip to the drill or grinding tool. Use a ceramic drill bit if you can get one, as it is designed for working with tiles, which are a similar material to seashells. A grinding tool will work well, but you need to get a small enough tip for the hole.
Position the drill or grinder on the taped shell. If you are using a drill, dip the bit in water first. This cools the bit, so it doesn't crack the shell.
Start the drill or grinding tool and press down. Press with enough force to start making a hole, but don't press too hard or you may shatter the shell. Drip water on the drill bit periodically to keep it cool. Push until the grinder or drill passes through the shell.
