Most plastic drill bit sets come with around 5-10 different bits. This means you get different sizes to match the different-diameter holes you want to make, as well as spares in case you suddenly find that one of your tips has gone blunt. It’s also considered best practice to use a lubricant when drilling for deeper holes. The lubricant aids in the removal of debris and dissipation of heat. Throughout the drilling process, you should keep a watchful eye on the area around the hole you’re making. In the event that you observe plastic shavings gumming up, you should immediately stop drilling, let plastic cool, clear out the hole, and then resume drilling. Once the acrylic has been prepared for drilling and is appropriately marked, the drilling process itself is extremely easy. Plastics happen to be a universal amenity of modern life. Whether it be kitchen cabinets or credit cards, plastics leave their imprint everywhere because of their diverse utility. If you’re wanting to utilize a plastic material for a DIY project, then you’ll probably want to know how to drill into plastic. However, you may be wondering if you can use a wood drill bit on plastic or if you need a special kind of bit. Further, if you don’t have a drill, you might be wondering if you can make a hole in plastic without a drill?
For drilling harder plastics such as acrylic and plexiglass, you might want a stronger bit with a more traditional tip. Metal and masonry drill bits are designed to bite into the material, meaning they can be quite rough on plastics. It’s also crucial that you use a drill bit designed for plastic, given how difficult it can be to create a clean hole using any other type of bit. Conical drill bits are perfect for use with thin PLEXIGLAS® sheets and PLEXIGLAS® corrugated sheets and tubes. These result in slightly conical holes, which prevent chipping on the exit side of the hole.Despite this, the Brad point design does well to allow for easy drilling – the bit won’t “walk” across your surface, which is great. Given their reasonable price, the durability is great, due to the titanium coating. If you’re only ever going to be drilling plastic, these bits will stay sharp basically forever.
Prior to drilling a hole in the plastic, it’s recommended to clamp down the plastic material securely to a bench or solid surface. This helps make sure that the plastic object stays stationary throughout the drilling process. So, your chances of ruining the material by drilling are minimized. In addition, it is recommended that you place a spare piece of plywood underneath the plastic object. The plywood acts as a barrier and helps minimize your chances of chipping the surface on the bottom.

Cut edges can be sanded down with some wet and dry paper or very fine sand paper. How to Drill Acrylic or Perspex The most important thing to remember when drilling into plastic is how brittle the material can be when compared wood, concrete, or aluminum. Acrylic sheets are an integral part of the modern household, thus you may find yourself needing to drill through acrylic at some point. However, this is no easy task and requires a special kind of drill bit. Essentially, there are four things to look for when finding the best type of drill bit for acrylic, we’ve listed them for you below. Now, there are a few steps you need to take to ensure your acrylic is ready to be drilled. By following this advice, you are less likely to cause damage to or break your acrylic sheet during the drilling process.
If you’re planning to drill into plastic, you may be wondering, can I use a wood drill bit on plastic? The simple answer is yes, but it’s not the ideal bit. The best drill bit to use on plastic is a dowel bit, also known as a spur-point bit. These are long, spiral-shaped bits with a sharp point on the end. This is because they come with an ultra-sharp four-point tip, designed to make an easy, clean entry into the material you’re drilling, without using excessive force. The answer is technically yes, you could theoretically heat the acrylic to a point where it melts and cut through it once it softens, this method is highly discouraged due to its significant dangers. Acrylic, like other plastics, can emit harmful gases when heated or burned, including hydrogen cyanide, carbon monoxide, and other potentially harmful substances. This method also carries a high risk of burns and fires. For drilling holes of large diameter a hole saw with fine tooth pitch can be used with thin materials. A low rotational speed and adequate water cooling are important here. The spaces between the teeth of the hole saw should be cleaned regularly. For this type of drilling, the workpiece must be well secured.The best drill bits for this job are Titanium coated and will remain shorp through this and many more jobs. When it comes to managing noise and reducing unwanted sound, clear acrylic Perspex is a material that holds great promise. We will explore the sound These are some of the only drill bits you can buy right now that are designed specifically for use on plastics, including hard plastics such as acrylic. Rather than using a Brad point/dowel/spur bit, you can also use a step drill bit to make clean holes in plastic.
Many adhesives are plastics themselves. A good example is ‘Araldite’ which is an epoxy resin that hardens when a second chemical is added (called a catalyst). It can bond most materials including some plastics. The two tubes can be seen in the diagram. An equal amount of each tube are mixed together and then applied to the material to be glued. Some say that drilling a hole in plastic without a drill requires melting the plastic. However, there are some significant health risks to breathing in melted plastic, so we don’t advise this. Your best bet at puncturing a hole in plastic without a drill will be to clamp down a thin piece of plastic, and then hold a screwdriver where you want to make the hole and hit the top of it with a hammer. However, feel free to get creative here, just know that you probably won’t make a good-looking hole. What is the Best Type of Drill Bit for Acrylic?As for the actual drilling technique, you want to apply a consistent but firm amount of pressure to the drill, to prevent the bit moving as you drill. You can technically use traditional masonry bits or wood bits for drilling through plastic, with the right technique. However, these types of bits often leave a sharp edge and a poor-quality finish when drilling through plastic, because they’re designed to bite into the material.
