In this particular set, you get 7 drill bits, each a different size. Although there are no spares, we don’t mind this, because these bits are super durable. If you’re drilling a hole for a screw in wood, you will need a drill bit that’s slightly smaller than the screw you’re planning to use so that the screw’s thread will tap into the material. If you’re drilling a hole more than 10mm in diameter, you may be better off with a completely different, more specialist type of drill bit, like a Forstner bit, a spade drill bit, or, for much better holes, a hole saw. What does a metal or plastic drill bit look like? A lot of plastic pots have these built-in drip trays at the bottom. This is great and can help to prevent root rot, but it’s not as good as a drainage hole. If you have a very hard plastic pot, you will need a diamond drill bit to drill through it. These are also sometimes labeled as masonry drill bits.
For 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. Drill bit for plastic deep dive When drilling plastic, it is critical to use a slower drill speed. This will keep the high speeds from causing tremendous friction, and therefore melting through the plastic. 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. However, this doesn’t mean it’s easy to drill into all other types of plastic. When drilling into thin, soft plastic for instance, you may want to place some scrap wood behind it to allow for easier drilling. Will plastic wear down my drill bits?
Conclusion
Diamond drill bit for large holes or a super hard pot. Sharp twist bit for regular plastic pot (see my guide to drill bits for each pot type below) 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. 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.
Cobalt drill bits are much harder at higher temperatures making them good for drilling through stainless steel and other hard materials, though they are usually way in excess of what most DIYers need.
Best Drill Bits For Plastic
In this guide, we take a look at the best drill bits for plastic and share some tips on how to get the cleanest, smoothest holes when drilling this material. Which Drill Bits to Use on Plastic Each drill bit is designed for different purposes. For example, drill bits for concrete are not the same as those for plastics. 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. If you’re just looking to punch some holes in a plastic lid, then going for a single 3/16″ drill bit will do you fine.
Metal and masonry drill bits are designed to bite into the material, meaning they can be quite rough on plastics. More gentle bits designed for use with wood will perform a little better, but may not have the right style of tip to make a clean entry into the plastic you’re drilling. Is it worth buying a drill bit set? 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. When you water plants, water usually settles down to the bottom of the pot. Sitting water can lead to mold or rot. Once you’ve chosen your drill bits, it’s time to get to work. Generally speaking, plastic is not very hard to drill. There are a few things to note if you want to get smooth, clean holes.

How to drill into plastic Toughness is paramount when drilling into metal because the heat generated can easily spell the end for cheap drill bits.

They’re likely to last longer, and they will not get lost as they come in a soft-grip plastic case which is clearly labelled, making finding bits and returning them to their correct slot a simple task. It’s also finished in Draper’s trademark blue, making it easier to spot at the bottom of a tool bag. A set of multi-purpose bits in various sizes will always come in handy. For plastics, these bits are versatile and easy to use. When choosing your bits, look for precision ground bits. These bits are tough, making them ideal for a variety of materials, including softer plastics and acrylic. Standard HSS bits

The best drill bits you can buy in 2023
There are many good brands of drill bits for plastic. But it’s essential to know the factors you should look for before having it. Whether you’re a beginner or experienced in the art of drilling, there are some considerations when choosing your drill bit. Should I Think About The Material? The larger the hole you are drilling, the slower you will need to drill. If you drill too fast, the plastic will melt. You will need to go especially slowly as the bit exits the plastic. It is a good idea to clamp the plastic to a hard surface before you start. You can do this by adding a piece of plywood below the plastic. This will prevent the plastic from being chipped as you reach the bottom of the surface. Have a plastic pot that doesn’t drain water? It’s an easy fix! Here’s how to drill holes in a plastic pot for drainage! Place a pot with drain holes (like the plastic nursery pot a plant comes in) inside a larger pot.
