Use a drill with a sharp-tipped bit
Drilling holes in a plastic bin can be done in several ways, one of the most effective methods is to use an electric drill with a sharp-tipped bit. This method is relatively straightforward and can be done in a few simple steps.
Firstly, it is important to select the appropriate drill bit size, depending on the size of the intended holes. For larger holes, a bigger bit is required, whereas smaller bits are more suitable for tiny holes. The speed of the drill can also be adjusted to suit the desired outcome. A slower speed will create smoother, smaller holes, while a higher speed can be used for quicker drilling but may result in less precision.
When drilling into plastic, it is crucial to avoid applying excessive pressure, as this can cause the plastic to crack. Instead, let the weight of the drill carry the bit through the material. To achieve a clean cut, some people find it helpful to draw the desired hole pattern on paper, tape it to the bin, and then drill along the pattern. This ensures accuracy and can help prevent mistakes.
For thicker or harder plastics, heating the drill bit can be beneficial. This can be done by heating the blunt end, not the drilling tip, and then melting the holes through the plastic. Alternatively, a soldering iron can be used to melt the holes, but this may result in larger holes in colder climates.
By following these steps and taking appropriate safety precautions, drilling holes in a plastic bin with an electric drill and a sharp-tipped bit can be a safe and effective method for creating the desired holes in the plastic bin.

Avoid applying too much pressure to prevent cracking
Drilling holes in plastic containers can be a tricky task, as applying too much pressure can cause the plastic to crack. Here are some tips to help prevent cracking when drilling holes in a plastic bin:
Firstly, it is important to use the correct tools and techniques. Using a sharp drill bit specifically designed for plastic drilling is crucial. Choose a drill bit size that corresponds to the desired hole size in the bin. Additionally, using a drill stand or press can provide more control and stability during the drilling process. This setup ensures that the weight of the drill itself carries the bit through the plastic, reducing the need for excessive pressure.
The speed of the drill is another critical factor. Drilling at a slow speed can help prevent cracking. Start drilling slowly and increase the speed gradually as needed. Additionally, varying the speed, starting at a higher speed to cut through the centre and slowing down as you punch through the backside, can help achieve smooth results without applying too much pressure.
For harder plastics, heating the drill bit can be advantageous. Instead of applying force, let the heated drill bit melt through the plastic slowly. This technique is especially useful for creating smaller holes. You can heat the drill bit by using a lighter or melting a hot screwdriver with a lighter and then drilling. Alternatively, you can heat the blunt end of the drill bit, not the drilling tip, to melt the holes through the plastic.
Another method to avoid cracking is to use a soldering iron instead of a drill. Soldering irons are effective for creating holes in plastic and can be purchased at a low cost. The size of the hole can be controlled by adjusting the pressure and temperature of the soldering iron. However, this method may not work well in colder climates, as it can result in larger holes.
Finally, for thin plastics, it is recommended to use a step drill. Step drills have the advantage of reduced spiral action, minimising the risk of the plastic spinning out of control and cracking. Sandwiched the thin plastic between two pieces of sacrificial wood to provide rigidity and prevent cracking during drilling.

Use a soldering iron instead of a drill
Using a soldering iron is a good alternative to a drill for making holes in plastic bins. It is a handy tool for creating holes in plastic containers, as it can be used to make holes of various sizes. The size of the hole is determined by how hard you press and how hot the soldering iron is. For example, you can use a soldering iron to make holes small enough for 3/4 slings to fit through or for up to 6" adults, all with the same iron tip.
One advantage of using a soldering iron is that it can be used on different types of plastic, such as hard plastic containers, large pretzel jars, and Tupperware. It is also a good option if you are looking for an inexpensive tool, as a soldering iron can be purchased for under $10.
However, there are some downsides to using a soldering iron. One is that it may not work well in colder climates, as the holes may become too big. Additionally, it is not suitable for use on metal surfaces.
To use a soldering iron to make holes in a plastic bin, you can follow these general steps:
- Plug in the soldering iron and turn it on to heat up.
- Determine the size of the hole you need and adjust the pressure and temperature of the soldering iron accordingly.
- Hold the soldering iron firmly and press it against the plastic bin where you want the hole to be.
- Apply pressure and move the soldering iron in a circular motion to melt the plastic and create the hole.
- Repeat as needed for additional holes.
- Allow the plastic to cool down and harden before using the bin.

Wash the bin with soap and water after drilling to remove toxins
Drilling holes in plastic bins is a straightforward process that can be completed in a few simple steps. The first step is to gather your materials, which include a drill and a drill bit. The size of the drill bit will depend on the size of the container and its intended use. For example, a user on Arachnoboards recommends using bits ranging from 1/16 to 5/32 for container store enclosures.
The next step is to plan out the placement of the holes. One Arachnoboards user drew the hole pattern on paper, taped it to the container, and then began drilling. This user recommends using a slow speed when drilling through plastic to avoid cracks and melting. They also advise varying the speed of the drill bit, cutting through the center faster, and slowing down to a crawl to punch through the backside.
Once you have drilled all the holes, it is important to wash the bin with soap and water to remove any toxins released by the heated plastic. One Arachnoboards user recommends turning on the exhaust fan before drilling to reduce the number of toxins released. After drilling, use your finger to rub the inside of each hole to ensure there are no sharp edges that could cause injury. Finally, wash the bin with soap and warm water to remove any remaining toxins. It is important to avoid using abrasive cleaning materials, as these can scratch and cloud the plastic.
Washing a plastic bin with soap and water is a simple process. First, fill a sink with warm water and add a few cups of soap. Separate the bin into its component parts, such as the lid and bottom, and soak them in the soapy water for about 10 minutes. Then, rinse and dry the bin thoroughly before using it again. This process will remove any toxins that may have been released during the drilling process, ensuring that the bin is safe to use for its intended purpose.
In conclusion, drilling holes in a plastic bin is a quick and easy task that can be completed with a few tools and safety precautions. The most important step is to wash the bin with soap and water after drilling to remove any harmful toxins that may have been released during the drilling process. By following these steps, you can safely and effectively drill holes in a plastic bin while minimizing the risk of injury or exposure to toxins.

Drill slowly and let the drill bit melt the plastic
Drilling holes in a plastic bin requires some care to avoid damaging the plastic. One of the biggest challenges when drilling into plastic is that the material can melt due to the heat generated by friction. To avoid this, it's important to use a slow drill speed, especially when creating larger holes. Drilling at high speeds can quickly generate too much heat, causing the plastic to warp or melt.
When drilling, it's recommended to use a sharp, new drill bit and apply light, steady pressure. You can use a standard twist HSS (High-Speed Steel) drill bit, which is commonly used for drilling acrylic or plastic. Before drilling, it's important to clamp down the plastic securely to a solid surface and back it up with a spare piece of plywood underneath. This will prevent the drill bit from damaging the surface when it exits the plastic.
To further reduce the risk of melting or cracking the plastic, you can also apply a lubricant to the drill bit to help remove debris and dissipate heat. Water with dish soap can also be used to cool the drill bit if necessary. Additionally, you can create a small pilot hole with a smaller drill bit before switching to a larger bit to create the desired hole size. This is especially helpful when drilling into thicker or harder plastics.
By following these steps and drilling slowly, you can let the drill bit "melt" the plastic, creating smooth, clean holes without damaging the bin. After drilling, you can use fine sandpaper to smooth out any rough edges and ensure a clean finish.
