Choose the right drill and drill bit
Drilling holes in plastic beads requires precision and safety. To achieve the best results, it is crucial to select the appropriate drill and drill bit. Here are some factors to consider when choosing the right tools for the job:
Choose the Right Drill
The type of drill you use depends on the material of the bead and the precision required. For plastic beads, a handheld rotary tool or a conventional cordless drill is commonly used. These drills allow for better control and precision compared to more powerful options. A drill press can also be used, but it may be challenging to prevent the bead from slipping and twisting.
Select a Suitable Drill Bit
Selecting the correct drill bit is essential for achieving the desired outcome without damaging the bead. Here are some factors to consider when choosing a drill bit:
- Material: Use a drill bit specifically designed for drilling into plastic. Metal drill bits can also be used, but they may generate too much heat, causing the plastic to melt.
- Size: Choose a drill bit that corresponds to the desired size of the hole. For small holes, select a bit that is no larger than 1/8 inch (3.175 mm). Smaller beads may require even smaller drill bits.
- Coating: Consider using a diamond-coated or carbide-tipped drill bit to reduce the risk of cracking or shattering the bead. These coatings provide a smoother drilling experience and minimize heat generation.
- Speed: Opt for a variable speed drill or a drill with adjustable speed settings. This allows you to start drilling at a slow speed to prevent damage and gradually increase the speed as needed.
- Cooling: To prevent overheating, consider using water or oil to lubricate the drill bit and keep the plastic cool during the drilling process. Alternatively, submerge the bead in water to keep the drill bit cool.
- Stability: Secure the bead properly to prevent movement. Use putty, a rubber pad, or a soft cloth to keep the bead in place while drilling. This helps ensure stability and even pressure during the drilling process.
By carefully selecting the right drill and drill bit, you can effectively drill holes in plastic beads while maintaining precision and safety. Remember to practice proper technique, wear protective gear, and work in a well-ventilated area for the best results.

Prepare the bead and your work area
To prepare the bead and your work area, you will need to gather the right tools and materials and set up your workspace safely. Here is a step-by-step guide:
- Choose the right drill for the job. A hand-held rotary tool or a conventional cordless drill can be used to drill holes in beads. However, for plastic beads, it is recommended to use a drill with small bits designed for plastics, such as carbide-tipped or high-speed steel bits. Vice drills, which are pencil-shaped vices with small drill bits, are also suitable for drilling plastic beads and are available in craft stores.
- Select the appropriate drill bit size. Ensure that the drill bit matches the size of the hole you want to create. For plastic beads, it is crucial to use a drill bit specifically designed for use with plastics to prevent cracking or shattering the bead.
- Gather other tools and materials. You will need safety goggles and gloves to protect your eyes and hands from debris and potential injuries. It is also recommended to have toy putty or poster putty to secure the bead in place while drilling. Alternatively, you can use a clamp with rubber on the grabbing surfaces or cover the surfaces with electrical tape.
- Set up your work area. Ensure your work area is well-ventilated and free from any distractions or obstructions that could interfere with the drilling process. Make sure you have a stable work surface to place your tools and materials on.
- Prepare the bead. If you are drilling into a clay bead, it is recommended to indent the surface with a toothpick before baking to guide your drilling. If you are drilling into a baked bead, you can use a rigid metal pin or needle to create an indentation. Mark the spot you want to drill with a pencil or marker if no indentation is possible.
By following these steps, you can safely and effectively prepare the plastic bead and your work area for drilling.

Secure the bead
Securing the bead is an important step in the process of drilling holes in plastic beads. Here are some detailed instructions to ensure the bead is securely held in place:
First, it is important to use a stable work surface. A small clamp can be used to secure the bead, with the drilling side facing up. Some clamps have rubber on the grabbing surfaces, or you could cover the clamp with electrical tape to protect the bead from scratches. If you don't have a clamp, consider using a vise with plastic jaws or two pieces of wood with a bolt through to hold the bead.
Next, to prevent the bead from moving, you can press it into a thick layer of putty, such as toy putty or poster putty. This will keep the bead stable and prevent it from spinning when drilling.
Alternatively, you can use a drill press, but this may require extra care to prevent the bead from slipping and twisting. You can try using a grip of some sort around the bead to secure it.
For polymer clay beads, you can use Amaco Bead Piercing Pins to create a small hole that will help guide your drilling. The pin can be left in the bead during baking and removed while the clay is still warm, creating a clear hole.
Once you have secured the bead, you can begin the drilling process, starting at a slow speed to prevent cracking or shattering the plastic bead.
