If so, we suggest heading to one of our category pages on:.Pause or slow down to re-lubricate the drill to prevent it from overheating.During the drilling process, apply little but firm pressure to the drill.Lubricants such as WD40, canola oil, or even vegetable oil. While drilling, apply a lubricant to remove unwanted debris and reduce heat, especially when drilling deeper holes.To keep the other parts of the plastic from cracking, place painter's tape to the area where you intend to drill.Clamp the plastic tightly to a stable surface and use a spare piece of plywood underneath to support the portion of the plastic you are drilling.You can do the following steps when drilling plastics or acrylics to prevent this from cracking : A slower pace will also enable the chips to exit the hole immediately-the greater the size of the hole, the slower the speed of the drill. This will keep the high speeds from causing tremendous friction, and therefore melting through the plastic. When drilling plastic, it is critical to use a slower drill speed. Unlike concrete and wood there are some clear differences when drilling plastic, such as the need to drill 1-2 mm larger than the screws, to allow for both contraction and thermal expansion. How to make a hole in plastic without cracking itĭrilling plastic might appear simple, but if you are not careful, you may end up with splinters and cracks. The resulting hole is clean and free of burrs. For example, step bits are excellent for drilling holes in plastic or acrylic because they can create smooth-walled and straight hole sidewalls. They can also be used for softer materials such as aluminum, wood, and plastic. They are used for drilling holes in bronze, cast iron, and steel. They are usually made from steel, cobalt, or carbide-tipped. Dowel bits or Spur-point Drill bitsĪ step drill is a cone-shaped drill with increasing diameters, often known as a stepped drill bit. One of the significant differences between bits is their physical shape, materials, or geometry. The difference in drill bits is affected by a variety of factors. For example, drill bits for concrete are not the same as those for plastics. Drill bit for plastic deep diveĮach drill bit is designed for different purposes. Twist HSS (High Speed Steel) drill bitsįor more information we suggest reading on, as there are some significant differences with these drill bits and particular points when you should and shouldn’t be using them.If you are in the process of figuring out what type of drill bit you need for drilling plastic, then to give you a quick idea, any of the following will work: Knowing the right way to drill holes in plastic will save you a lot of time and resources. It’s especially used when you need to make holes of a very precise size. Choosing the correct type of drill for plastic is essential to ensure that your holes are uniformly shaped, clean, and undamaged. Finally, reaming is a process through which an existing hole is smoothened. ![]()
