There are various methods to create a hole in plastic, depending on the type of plastic and the tools available. For thin plastic, it is recommended to have a piece of wood or something similar behind the plastic to prevent breakage. A drill is the most effective tool for the job, with step drills or step-bit drills being the best option for brittle plastic. If you don't have access to a drill, other methods include using a soldering iron, a hot nail, or a screwdriver heated over a fire source.

What You'll Learn
Using a hot nail
To use the hot nail method, you will need a nail, preferably a bigger one, and a pair of pliers to hold the nail. If you do not have pliers, you can use tongs or a vice grip to hold the nail. You will also need a fire source, such as a butane lighter, stove, or another fire source to heat the nail.
Before you begin, ensure you are working on a solid, non-flammable surface, such as concrete. If you are working indoors, make sure the area is well-ventilated as some plastics release fumes when melted. Additionally, it is recommended to have a piece of wood or another flat, non-flammable surface behind the plastic to prevent any damage to your work surface.
Once you have gathered your materials and set up your workspace, you can begin heating the nail. Hold the nail with the pliers or tongs and heat it over the flame until it is red hot. If you are using a lighter, you may need to reheat the nail multiple times as it may cool down quickly.
Once the nail is hot enough, slowly and carefully push it through the plastic where you want the hole to be. You can control the size of the hole by adjusting the pressure and temperature of the nail. For smaller holes, use a slender nail and apply less pressure. For larger holes, use a thicker nail and apply more pressure while the nail is hotter.
When you are finished, allow the nail to cool down before handling. Clean up any plastic residue with a file or sandpaper. Wash the plastic with soap and water to remove any toxins from the heating process.

Drilling with a step drill bit
When using a step drill bit, it is important to first consider the thickness of the plastic. If the plastic is thin, place a piece of wood or plywood behind it for support. This will prevent the plastic from breaking when the drill bit breaches the back. You can also use painter's tape on the area to be drilled to help keep the plastic from cracking.
To drill the hole, apply firm but gentle pressure to the step drill bit. Unlike when drilling metal, you do not need to use lubricating oil when drilling plastic. However, you can use a lubricant like WD40, canola oil, or vegetable oil to help remove debris and reduce heat when drilling deeper holes. Be sure to pause and re-lubricate if the drill starts to overheat.
Step drill bits come in various sizes, and a single bit can drill holes of different diameters. This eliminates the need to change bits frequently. However, some step drill bits require the use of a punch before drilling. Choose a step drill bit with a diameter that matches the desired hole size, or use a smaller bit to save effort and prolong the life of the bit.
Overall, drilling with a step drill bit is a precise and effective way to create holes in plastic. By following these steps and choosing the appropriate bit size, you can achieve clean and uniformly shaped holes without damaging the plastic.

Hand-held tapered reamer
Tapered reamers are a great tool for creating holes in plastic. They are available in a range of sizes and can be purchased from online retailers such as Amazon and eBay. When using a hand-held tapered reamer, it is important to follow these steps to ensure a successful hole-making process:
Firstly, ensure you have the correct size of tapered reamer for the desired hole size. The reamer should be slightly larger than the hole you wish to create. It is also important to select the appropriate type of reamer for the material you are working with. In this case, a tapered reamer suitable for use with plastics should be selected.
Before beginning the hole-making process, it is essential to prepare the plastic by marking the centre point of the desired hole with a marker or pencil. This will guide the placement of the reamer and ensure accuracy. Additionally, clamping the plastic securely to a workbench or stable surface will provide stability and control during the process.
Holding the reamer firmly with both hands, position the tip of the reamer directly over the marked centre point. Apply gentle pressure and begin to rotate the reamer in a clockwise direction. It is important to maintain a slow and steady rotation to avoid cracking or damaging the plastic.
As the reamer penetrates the plastic, gradually increase the pressure while continuing the clockwise rotation. The tapered design of the reamer will cut through the plastic, enlarging the hole with each rotation. To achieve a smooth and precise hole, it is crucial to maintain control and apply even pressure during this process.
Once the reamer has passed through the plastic, slowly withdraw it by rotating it in a counter-clockwise direction. This will ensure that the edges of the hole are smooth and free of any burrs or roughness. If necessary, you can repeat the process to refine the hole further or to create additional holes in the plastic.
By following these steps and using a hand-held tapered reamer, you can effectively create holes in plastic. Remember to take appropriate safety precautions, such as wearing protective eyewear and gloves, to ensure a safe working environment.

Soldering iron
A soldering iron can be used to create holes in plastic. It is particularly useful when working with thermoplastics, which are designed to be manipulated under heat. The process is simple: turn on the soldering iron and allow it to heat up, then apply light pressure to the desired location on the plastic with the tip of the iron. The heat from the iron will melt a neat hole through the plastic. It is important to work in a well-ventilated area and to be cautious of the hot iron and melted plastic, which can cause burns.
While a soldering iron can be an effective tool for creating holes in plastic, it may not be suitable for all types of plastic or projects. For example, it may not work well on metal and can result in messy edges on sheets of acrylic. Additionally, regulating the size of the hole can be challenging, as the plastic may stick to the soldering iron and cause the hole to expand.
To overcome this issue, it is recommended to use a step drill bit, which allows for precise drilling and better control over the hole size. A drill bit designed specifically for plastics will typically create a clean cut, reducing the need for additional smoothing. For thin plastics, a hot sewing needle or a small nail can also be used to create holes, depending on the desired size.
When working with thicker plastics, such as acrylic, a drill can be an effective tool. It is recommended to start with a small drill bit and gradually increase the size until the desired hole diameter is achieved. To prevent cracking, it is important to use sharp drill bits, high speed, and low torque. Additionally, having a solid backing, such as a piece of wood, can provide support for the plastic and reduce the risk of cracking during drilling.
Overall, while a soldering iron can be used to create holes in plastic, it may have limitations depending on the specific project and type of plastic. Alternative tools, such as drill bits and sewing needles, offer more precision and control over the hole size and edge smoothness.

Scissors
Using scissors to cut holes in plastic is possible, but it is not a common method. The technique is more likely to be successful on softer plastic cases.
To start, you will need to draw the hole pattern on paper and tape it to the plastic. This will give you a template to work with. Next, you will need to choose a pair of scissors that are suitable for cutting through plastic. Attempt to begin cutting the hole by snipping away at the plastic. It is important to be very careful when using scissors, as it can be easy to slip and cut yourself.
If you are cutting a large hole, you may need to cut away the plastic in sections. Work slowly and deliberately, and be mindful of your fingers. Take breaks if your hands become tired, as this can increase the risk of injury.
For smaller holes, you can heat a small screwdriver with a lighter and melt the plastic. This can be done in conjunction with scissors, using the screwdriver to melt the plastic and the scissors to cut away the excess.
It is important to note that using scissors to cut holes in plastic may not always be effective, especially for harder plastics. Other methods, such as using a drill or soldering iron, may be more successful.
