About this deal

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? Drilling holes in the bottom of a pot is an easy way to add drainage. If there are holes – assuming they aren’t clogged by anything – there’s no way that your plant will get water logged. 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? If you plan to keep your pot indoors, add a drop tray underneath to avoid extra water dripping out onto your tabletop. Types of drill bits for each type of pot:

However, if you’re often working with acrylics or other types of plastic, going for a set is a great idea. 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 In this section, we’ve reviewed the 6 best drill bits for plastic for sale right now, including drill bit sets.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?

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. 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. Sometimes you need an ultra-sharp drill bit for a specific task. Most people have a go-to drill bit that works well on nearly everything. But if you often work in materials like aluminum or plastics, investing in titanium step bits might be a good idea. And the Sniper drill bit comes with titanium and high-speed steel. 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 plasticYou 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. 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. 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. Most of the drill bits you’re likely to encounter will bear the abbreviation HSS, for high speed steel. It’s a steel, alloyed with a range of other metals, designed to withstand the extreme temperatures generated by drilling through harder materials at high speed, hence the name. But, despite the high breaking strength they exhibit, they’re also brittle and don’t offer much resistance to bending. Which means it’s easy to snap thinner bits with even the most innocuous of impacts. Place a pot with drain holes (like the plastic nursery pot a plant comes in) inside a larger pot. Water can dribble out the inner pot and it won’t get soggy.

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. But be careful to look closely at the bits included in a given set. There’s not much point buying drill bits you’re never going to use. However, it can be nice to have easy access to that drill bit you’ll use every few months or so. While drilling, apply a lubricant to remove unwanted debris and reduce heat, especially when drilling deeper holes. Lubricants such as WD40, canola oil, or even vegetable oil.Choosing the correct type of drill for plastic is essential to ensure that your holes are uniformly shaped, clean, and undamaged. Knowing the right way to drill holes in plastic will save you a lot of time and resources. 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. Metal and masonry drill bits are designed to bite into the material, meaning they can be quite rough on plastics. But it’s definitely worth spending the time and doing your homework because there’s nothing more frustrating than not having the correct size or type of drill bit to hand when you need it, or to find the bits disintegrating right in the middle of a delicate job. The best solution is to add drainage holes to the bottom of your plant. Many pots come with drainage holes in them, but some do not! Why are drainage holes so important?

You don’t want 2 holes too close together or it could compromise the strength of the plastic in between them. Video demonstration Smaller diameter drill bits tend to be easy to break, so it’s a helpful touch that Draper has doubled up on the 1.5, 2.0, and 2.5mm bits. And the inclusion of a 3.2mm bit, in addition to the 3.0 and 3.5mm bits, is helpful too. 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.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. 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.
