They come with a 60-degree tip angle, which makes for a clean entry into both hard and soft plastic. Norseman’s bits are also designed to prevent grabbing or tear-outs, making them especially easy to use for beginners.

It’s easy to spend plenty of time researching for your next drill, but it’s just as important to find the very best drill bits for your project. That’s because when it comes to drill bits, all things are most certainly not equal. 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. The diameter of the bit head is one of the crucial considerations. Each drill bit’s size is listed as its diameter. More significant drill bits will have more surface area and will bore faster. But you need smaller drills when working on small delicate projects. So, you should know the diameter to have the perfect holes. Is The Diameter Connected with Length?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. The drill bits are not durable because they break very easily. Sometimes the drill bits’ sizes do not fit your drill, so you have to find other ways to use them.

The best drill bits for plastic have the proper size and hardness to go through rigid plastic. You can generally use a minor bit on smaller holes and a more significant bit on larger ones. However, as with any project, you will also want to consider the hole’s location in your project. It’s often best to use a drill bit that matches the size of your hole. So a little drill bit may be better for some applications than larger ones. What Next? The Diameter?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. We wouldn’t recommend drill bits you’ve bought for plastic be used on wood or masonry, or vice versa. 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.
