A light misting of water is also recommended to keep the cutter and plastic cool, and also to act as a cutting lubricant. 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. In general, when drilling a large hole, a slower drill speed setting should be used. This is because high speeds can melt the plastic. Further, be sure to bring the drill bit speed setting to a lower value every time the drill bit exits the plastic material. Never force your cut, this will cause the acrylic to over heat and possibly melt or disfigure the cut edge. The Acrylic will always come with a protective film or sheeting attached, leave this protective layer on the acrylic as long as you can, it will protect the finished surface of your acrylic.

Several drill bit geometries are described below that can be used with success, although most do not leave the inside diameter of the hole with a smooth finish. These bits require the same considerations for support behind the sheet and for cooling as previously reviewed for twist drills bits. Finally, you also need to bear in mind that plastic materials undergo expansions and contractions with fluctuations in temperature. So, you want to make sure that your drilled hole is slightly larger than required. Doing so will allow screws placed in those holes to move freely without exerting unnecessary stress on the plastic material. How Do You Drill a Hole in Plastic Without a Drill?ACRYLITE® sheet must be adequately supported and clamped to prevent flexing or vibration during the cutting operation. The material should also be placed as close to the fly cutter as possible to reduce the distance the cutter has to travel. Your project may require you to drill acrylic. So, it is vital to note that despite these highly desirable qualities, drilling acrylic can pose a risk to the condition of your plastic. What can go wrong?

When using a jigsaw to cut Acrylic make sure the cutting speed is as high as you can achieve with your saw. If you are producing straight line cuts the use of a straight edge clamped into position will ease the cutting process and give you a correct cut. The Jig Saw is the most suitable tool to also give you curved cuts in Acrylic. Hand saws can be used but because of the speed of the cutting action, a Jig Saw will give a smoother more constant finish. The drill bit size you need for a wall plug will depend on which wall plug you use. Generally, you’ll need a drill bit that’s the same diameter (in millimetres) as the wall plug, but for accuracy, you can drill a pilot hole using a slightly smaller size drill bit first. White wall plugs can vary in diameter (6-10mm). So, to drill a hole for a white wall plug, you will need a drill bit that’s the same diameter as the plug you choose. However, for added convenience, you might want to choose a drill bit that comes as a set. This is because you will get the tools in different sizes. Carbide-tipped: one of the hardest materials on the planet, this drill bit only uses carbide on the tip. It’s suitable for drilling masonry, tiles and concrete.

Safety is always integral when you drill acrylic, the dust can severely damage your eyes if you don’t protect them, so wearing safety goggles is key. Most brown wall plugs are 7mm in diameter, so to drill a hole for a brown plug, you will need a 7mm drill bit. HSS is an acronym for High-Speed Steel. The properties which make HSS Drill Bits an ideal choice to drill acrylic are their suitability for harder materials such as metal, wood, and acrylic, as well as their ability to withstand the heat generated from fast-speed operation. HSS Drill Bits are superior to ordinary carbide drill bits and can last for at least 150 holes and to a maximum of 450 before they become too worn to function effectively. Masking tape will help to provide an extra barrier while you drill acrylic, which will prevent the teeth from damaging their surface. Once you have all the recommended equipment on hand, it's time to start drilling. Some tips that we at Sheet Plastics have compiled to achieve the best results include:

The best part? For maximum durability, the drill bits are constructed from C-3 Tungsten Carbide which is the hardest and most versatile material.
Final Thoughts
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. Hex shank - A hexagonal-shaped shank used in screw guns or electric screwdrivers with a hammer mode.

A HSS drill bit is made from high-speed steel, as described in the materials section above. It’s often used in multi-purpose drill bits as it can be used on wood, plastic and metal. HSS drill bits are also the best drill bits for soft metals. Grey wall plugs can vary in diameter (6-14mm). So, to drill a hole for a grey wall plug, you will need a drill bit that’s the same diameter as the plug you choose.For some projects, you may not know where you need your drilled holes or require extra holes and will need to drill them yourself. We’ve created this simple step-by-step guide to help you. Cut edges can be sanded down with some wet and dry paper or very fine sand paper. How to Drill Acrylic or Perspex
