Drilling a hole in a plastic box is a simple task that can be done in a variety of ways. The most common methods involve the use of a drill, with specific bits such as a step bit, Forstner bit, or standard jobber drill bits. Other methods include using a soldering iron, a hot screwdriver, or heating a piece of copper and melting a hole. The choice of method depends on the type of plastic, the size of the box, and personal preference.

What You'll Learn
Using a soldering iron
Firstly, you should decide where you want the hole to be in your plastic box. It is a good idea to do this before you add any dirt or other contents to the box, although it is still possible to make holes once the box is filled. You can use a soldering iron on a full box, but it may be messier.
Next, heat up your soldering iron. You can then use the hot iron to melt a hole in the plastic. You can control the size of the hole by varying how hard you press and how hot the iron is. You can make the hole bigger by pressing harder and holding the iron in place for longer.
If you are making a larger hole, you may need to melt the plastic away in sections, or use a different tool to remove the remaining plastic once the soldering iron has made a pilot hole. You can use a screwdriver, for example, heating it with a lighter or on a stove, and then gently twisting it in circles to melt the plastic.
Be aware that some plastics make fumes when they are melted, so always use your soldering iron in a well-ventilated area.

Drilling at a slow speed
When drilling, it is recommended to use a small drill bit and increase the speed gradually as you cut through the plastic. This technique helps to control the process and prevent damage to the plastic. Start by centre punching and pilot drilling at a slow speed, then gradually increase the speed as you approach the final size. It is important to have support material above and below the drilling area to stabilize the plastic and prevent it from flexing or moving during the drilling process.
For hard plastics, it is essential to go slowly and let the drill bit "melt" the plastic. This technique ensures a smooth and controlled drilling process. You can also use a soldering iron with variable-sized tips to create holes in hard plastics. By adjusting the heat and pressure, you can control the size of the hole. However, be cautious as excessive heat can cause the plastic to melt or deform.
Additionally, consider using a step drill bit, which is specifically designed to create holes in plastic without ripping or causing excessive damage. Step drill bits have small cutting steps that gradually increase in size, allowing for a more controlled and precise drilling experience. They are ideal for creating holes in plastic boxes as they can help achieve a smooth finish without the risk of wallowing out the centre guide hole.
Overall, drilling at a slow speed and using the appropriate drill bits are crucial factors in successfully drilling holes in plastic boxes without causing damage or compromising the integrity of the material. By taking the time and using the right tools, you can achieve the desired results with smooth and precise holes.

Drilling with a step bit
Before you start drilling, it is important to clamp the plastic box tightly to a stable surface and use a spare piece of plywood underneath to support the portion of the box you are drilling. This will prevent the plastic from cracking and chipping. It is also recommended to place painter's tape over the area where you intend to drill to protect the surface.
When using a step bit, it is important to use a slow drill speed, especially when creating larger holes, as high speeds can melt the plastic. Adjust the speed of the drill as needed, slowing down or pausing to re-lubricate the drill to prevent overheating. You can use lubricants such as WD40, canola oil, or vegetable oil to help remove debris and reduce heat.
Apply light but firm pressure during the drilling process, and ensure that you drill a slightly larger hole than necessary to accommodate for the expansion and contraction of plastic with temperature changes. This will prevent stress on the material.
With the right techniques and precautions, you can successfully drill holes in a plastic box using a step bit, creating clean and uniformly shaped holes without damaging the plastic.

Drilling with a standard jobber drill
Drilling a hole in a plastic box can be done in several ways, and one of the most common methods is to use a standard jobber drill. Jobber drill bits are the most common and popular type of drill bits. They are best used in softer materials such as wood, composite, and soft metals. For plastic boxes, a standard jobber drill bit with a long length compared to its diameter can be used.
To begin the process, it is important to select the appropriate size of the drill bit. The size of the bit will depend on the size of the hole you want to create and the thickness of the plastic box. Smaller bits are generally recommended for drilling holes in plastic, as larger bits can cause the plastic to flex and crack. A 3/32" bit is a commonly used size for drilling holes in plastic, but you may need to use a smaller or larger bit depending on the specific requirements of your project.
Once you have selected the appropriate drill bit, it is important to set the drill to a slow speed. Drilling at high speeds can generate excessive heat, which can melt the plastic and cause it to crack. By drilling at a slow speed, you can carefully control the drilling process and avoid applying too much force, which can also lead to cracking.
As you start drilling, it is crucial to apply minimal pressure and let the weight of the drill carry the bit through the plastic. This gentle approach will help prevent the plastic from cracking or breaking. Additionally, it is recommended to vary the speed of the bit during the drilling process. You can cut through the center of the hole at a slightly faster speed, but remember to slow down as you approach the backside of the plastic to avoid sudden breakage.
When drilling with a standard jobber drill, it is also important to consider the type of plastic you are working with. Some plastics are harder and more brittle than others, and they may require additional techniques, such as heating the drill bit, to create holes successfully. However, heating the drill bit is not a necessary step for all types of plastic, and it may introduce the risk of inhaling toxic fumes. Therefore, it is advisable to research the specific type of plastic you are working with and follow safety guidelines to choose the most appropriate method.

Heating a screwdriver with a lighter
Drilling holes in plastic boxes can be done in several ways. One way is to use a soldering iron with variable-sized tips. Another way is to heat a small screwdriver with a lighter and melt the plastic. This method will be the focus of the following instructions.
Firstly, choose a small screwdriver that can be easily held and manipulated. You will also need a lighter and some form of protection for your hands, such as gloves or pot holders, to avoid any burns. It is also recommended to work in a well-ventilated area or turn on an exhaust fan to avoid inhaling any fumes from the melting plastic.
Once you have gathered your tools, light the lighter and hold the screwdriver in the flame until it is red hot. This may take a few seconds, so be patient and careful not to burn yourself. Once the screwdriver is hot enough, remove it from the flame and gently touch it to the plastic box where you want to create the hole. Hold the screwdriver in place for a few seconds, applying slight pressure, until the plastic begins to melt.
If the screwdriver cools down before the hole is complete, simply repeat the process by heating it with the lighter again. You can control the size of the hole by adjusting the temperature of the screwdriver and the amount of pressure you apply. For a larger hole, reheat the screwdriver and continue melting the plastic until you achieve the desired size.
After you have finished drilling the hole, it is important to clean the area. Wash the box with soap and water to remove any remaining plastic residue and toxins from the heating process. Ensure you also rub the inside of the hole with your finger to smooth out any sharp edges that may cause injury.
