What Can I Use to Cut a Hole in a Seashell?

Drill

• The ideal tool for cutting holes in shells is the drill, which cuts the hole with a bit that moves in a circular motion. Match the drill bit size to the desired hole-size, and understand if you cut a hole with too large a bit, you risk shattering the shell. Yoy have three basic drill types to choose from.
  
  

Electric Drill

• The best drill choice for cutting holes in seashells is the electric. If you place the shell on a cork surface, the cork will help absorb the vibrations that occur during drilling and will help prevent the shell from breaking. An electric drill is also a common tool found in the home toolbox, used for projects around the house.
  
  

Craft Drill

• A craft drill is also an electric drill, yet smaller than the typical electric drill that you find in the toolbox. It resembles a dental drill. This is an ideal tool for cutting holes in tiny, fragile shells.
  
  

Manual Drill

• The manual drill is a hand-operated drill that requires the use of both hands. One hand holds the tool while the other turns its handle. This type of drill is a bit difficult to use when cutting a hole in the shell, as the small shell will move around during the drilling process, and you need a third hand to hold it in place. Otherwise, you place it in a vice or a similar securing device, taking care not to clamp it too tight.
  
  

Safety

• Wear protective eyeglasses when cutting holes in hard objects, with the ever-present chance the process will send a sharp stray piece flying across the room. Wear protective gloves, as well as the protective eye gear, when drilling the hole. The power drill is a tool for adults, not children. If the shells are for a children’s craft project, have an adult precut the holes.
