Plexiglass is a durable, transparent material that is often used in place of glass. While it is strong and shatter-resistant, plexiglass can crack if not properly handled. Drilling holes into plexiglass can be tricky, but with the right technique, it is possible to drill holes without cracking the material. In this article, I’ll teach you how you can drill holes in plexiglass without cracking it. Let’s get started.
Plexiglass is a type of hard plastic that is used in a variety of applications. It is strong and durable, yet still transparent like glass. Because of these qualities, plexiglass is often used as an alternative to glass in windows, windshields, and other applications. When drilling into plexiglass, it is important to use a drill bit that is specifically designed for hard plastics.
What kind of drill bit is used for plexiglass?
For plexiglass, the best type of drill bit to use is a carbide-tipped drill bit. These bits are made with a harder material that is able to withstand the high drilling speeds needed to drill through plexiglass.
A carbide-tipped drill bit is the best choice for drilling through plexiglass. Carbide is a very hard material that stays sharp longer than other drill bit materials, making it ideal for repeated use on plexiglass. Carbide-tipped drill bits also create cleaner holes with less burr buildup around the edges.
What kind of drill machines for plexiglass?
When it comes to drilling plexiglass, you need to use a drill machine that is specifically designed for this type of material. There are a few different types of drill machines on the market that can be used for plexiglass, but not all of them are created equal.
Some of the most common drill machines for plexiglass include:
Rotary drills: These are the most common type of drill used for plexiglass. They are very versatile and can be used for a variety of applications.
Percussion drills: These drills are designed for more heavy-duty applications. They are often used to drill through tougher materials, such as metals.
Diamond tip drills: These drills are designed specifically for drilling through plexiglass. They are very sharp and can easily create clean and precise holes.
Drilling holes in plexiglass
Drilling holes in plexiglass can be a bit tricky, but with the right tools and a little know-how, it’s definitely doable. Here’s a quick step-by-step guide:
- Begin by using a sharp awl or similar pointed tool to make a starting indentation in the plexiglass. This will help keep your drill bit from slipping.
- Next, use a sharp bit designed specifically for drilling through the plastic. A spade bit or other type of hole saw can also work well.
- Apply gentle pressure as you drill, and keep the bit cool by regularly dipping it in water. Avoid putting too much pressure on the drill bit, as this can also cause the plexiglass to crack.
- Once you’ve drilled through the plexiglass, use a file or sandpaper to smooth out the edges
Tips for drilling holes in plexiglass
Use a sharp drill bit.
When drilling holes in plexiglass, it is important to use a sharp drill bit. A sharp bit will create a clean hole and help to prevent cracking or chipping of the material. Plexiglass is a strong and durable material, but it can be brittle and is therefore susceptible to damage if not drilled correctly. Using a sharp drill bit is the best way to ensure a clean, precise hole.
Use a slower speed
When drilling holes in plexiglass, it is important to use a slower speed than you would when drilling through other materials. This is because plexiglass is a softer material and is more likely to crack if drilled too quickly. By using a slower speed, you can avoid cracking the plexiglass and ensure a clean, precise hole.
Use a lubricant
There are a few reasons why you might want to use a lubricant while drilling holes in plexiglass. First, it can help to prevent the drill bit from overheating. Second, it can help to reduce the amount of friction between the drill bit and the plexiglass, which can make the drilling process easier and help to extend the life of your drill bit.
Go slowly
When drilling holes in plexiglass, it is important to go slowly in order to avoid cracking or shattering the material. Plexiglass is a type of thermoplastic, meaning that it is sensitive to heat. If the drill bit becomes too hot, it can cause the plexiglass to deform. Going slowly also helps to avoid creating too much friction, which can also lead to heat build-up.
Use a backing board
When drilling holes in plexiglass, it is important to use a backing board in order to avoid cracking or shattering the material. By using a backing board, the force of the drill is evenly distributed and helps to prevent the plexiglass from breaking.
FAQ
How to screw into plexiglass?
To screw into plexiglass, you will need to use a drill bit that is slightly smaller than the diameter of the screw. Drill slowly and carefully to avoid cracking the plexiglass. Start by making a pilot hole in the center of where you want to place the screw. Insert the screw into the pilot hole and tighten it until it is snug.
Are plexiglass and acrylic the same?
Plexiglass and acrylic are both thermoplastic materials. They have very similar properties, but there are some key differences between the two.
Plexiglass is a brand name for a specific type of acrylic sheeting. Acrylic is the generic name for a clear plastic that is often used in place of glass. It is lightweight, durable, and easy to work with. Plexiglass is often used in applications where glass would be too heavy or fragile, such as in car windows and skylights.
Acrylic is a cheaper alternative to plexiglass. It is not as scratch resistant as plexiglass, but it is easier to mold and shape.
How to repair a hole in the plexiglass?
If you have a hole in your plexiglass, there are a few different ways that you can repair it. You will need to decide what type of repair you need based on the size and location of the hole.
For small holes, you can use a clear epoxy. First, clean the area around the hole with a soft cloth. Then, mix the epoxy according to the manufacturer’s instructions. Apply the epoxy to the hole and allow it to dry.
For bigger holes, you will need to use a plexiglass patch. First, cut a piece of plexiglass that is slightly larger than the hole. Clean the area around the hole and then apply a layer of adhesive.
What speed to drill plexiglass?
Generally speaking, the best speed to drill plexiglass is between 3,000 and 4,000 revolutions per minute (RPM). This will ensure that the plexiglass is drilled quickly and smoothly. However, it is always best to consult with a professional before drilling plexiglass, as they will be able to provide specific advice based on your individual circumstances.
What kind of screws to use on plexiglass?
When it comes to choosing screws for plexiglass, it is important to consider the material’s unique properties. Plexiglass is a brittle material, meaning that it can crack or shatter under too much stress. Therefore, it is important to use screws that will not exert too much force on the plexiglass, which could cause it to break.
There are a few different types of screws that can be used on plexiglass. The most common type is a flat head screw, which has a wide, flat head that will distribute the force evenly over a large surface area. This reduces the risk of the screw causing the plexiglass to crack.

Conclusion
In conclusion, experts agree that you should use a drill only to drill holes in plexiglass. If you are using the drill for other purposes, the operator is likely to break something. Also, the drill will vibrate, so it is better to stand away from the plexiglass. Remember the drill is a useful tool, but like any other tool, it needs to be handled with care.
