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. In this section, we’ve reviewed the 6 best drill bits for plastic for sale right now, including drill bit sets.
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. We wouldn’t recommend drill bits you’ve bought for plastic be used on wood or masonry, or vice versa.
Our Top Picks
You can use a standard steel drill or an HSS drill to create your holes. If the drill bit is new, wear it in a little on a scrap piece of wood so that there is no risk of the sharpness tearing the acrylic. Step Four: Cut edges can be sanded down with some wet and dry paper or very fine sand paper. How to Drill Acrylic or Perspex For drilling harder plastics such as acrylic and plexiglass, you might want a stronger bit with a more traditional tip.
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. 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. Some people also like to use step drill bits for drilling plastic, to avoid having to change bits around to drill lots of different-size holes. The added benefit of these bits is they can make it easier to start your hole without the need for a countersink bit. What about the different types of plastic? Mirrors are objects that are used in everyday life, all around us! Whether that’s in your home, gym studio, or at an art gallery, these After the drill has passed through your material, place your acrylic sheet onto the flat surface and let it continue to operate. If you decide to fasten your material in place, take caution when doing so. Put something between the acrylic and the clamp to protect it.The other nice thing about sets is they often come with a nice holding case. This means you’ll always have easy access to your drill bits without having to rummage around for them, which is nice. How to drill into plastic 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. If you need prefabricated products or finished products made of PLEXIGLAS® or from one of our other brands, please get in touch with our fabricators. Rather than using a Brad point/dowel/spur bit, you can also use a step drill bit to make clean holes in plastic.
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. This might come as a surprise to you, but plastics are, in fact, drillable. However, one needs to adhere to a strict set of protocols when attempting to drill a hole through plastic materials. 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. Source One’s bit is a little expensive, but it’ll last a really long time. Just ensure that you get the right size, since you can’t buy this drill bit as a part of a set.Despite this, the Brad point design does well to allow for easy drilling – the bit won’t “walk” across your surface, which is great. 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. The best drill bits for plastic are spur (also known as dowel or Brad point) bits. These bits essentially have a four-point tip, which results in a much neater entry point and a cleaner hole. Perhaps the best glue is Tensol Cement which joins plastics such as perspex together permanently. The glue is applied to the surfaces to be glued and they are pressed together. They should be clamped for 24 hours and this gives a permanent joint. To ensure effective drilling into plastic, the most important thing is that the tip remains sharp. If the tip of your bit becomes dull over time, it will be much more likely to make a rough/jagged entry into the material you’re looking to drill.
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. However, if you’re often working with acrylics or other types of plastic, going for a set is a great idea. Milling drill bits allow production of the elongated holes used in connector systems, for example. It is particularly important to cool adequately with water when milling with milling drill bits.
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. Alternatively, you can use a countersink bit to create an initial depression in the plastic. This serves the same purpose as a dowel bit – ensuring that the bit is lined up and does not move as you begin to drill the hole. The shavings produced while drilling indicate whether the rotational speed is correct. The images show the influence of rotational speed or cutting speed and feed rate on the quality of the drill hole, in this case with a PLEXIGLAS® sheet.
