Product Information

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 brown wall plugs are 7mm in diameter, so to drill a hole for a brown plug, you will need a 7mm drill bit. 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. Flutes: a spiral channel that runs from the cutting lip to the shank. It helps to remove the material as it’s cut from the hole. And carbide – usually tungsten carbide – is a similarly tough material, and is commonly used in the manufacture of masonry drill bits.

They can also be used for softer materials such as aluminum, wood, and plastic. For example, step bits are excellent for drilling holes in plastic or acrylic because they can create smooth-walled and straight hole sidewalls. The resulting hole is clean and free of burrs.

How to Drill into Plastic with a Power Drill

Grey wall plugs can vary in diameter (6-14mm). So, to drill a hole for a grey wall plug, you will need a drill bit that’s the same diameter as the plug you choose. The drill bit size you need for a wall plug will depend on which wall plug you use. Generally, you’ll need a drill bit that’s the same diameter (in millimetres) as the wall plug, but for accuracy, you can drill a pilot hole using a slightly smaller size drill bit first. You should take precise measurements and mark the area where you will be drilling. You must use a slower drill speed setting when drilling a large hole. You can also use a lubricant when drilling for deeper holes. Always observe the area around the hole. Start drilling carefully with an ideal drill bit for plastic. Final Words

It’s also considered best practice to use a lubricant when drilling for deeper holes. The lubricant aids in the removal of debris and dissipation of heat. Throughout the drilling process, you should keep a watchful eye on the area around the hole you’re making. In the event that you observe plastic shavings gumming up, you should immediately stop drilling, let plastic cool, clear out the hole, and then resume drilling. For a start, drill bits are made from a number of different materials. And then the shape of the cutting face can be radically different depending on the material it’s designed to drill through. When you factor in price, the range of sizes available within a set, and the brand, the choice can be bewildering.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. Prior to drilling a hole in the plastic, it’s recommended to clamp down the plastic material securely to a bench or solid surface. This helps make sure that the plastic object stays stationary throughout the drilling process. So, your chances of ruining the material by drilling are minimized. In addition, it is recommended that you place a spare piece of plywood underneath the plastic object. The plywood acts as a barrier and helps minimize your chances of chipping the surface on the bottom. Finally, you also need to bear in mind that plastic materials undergo expansions and contractions with fluctuations in temperature. So, you want to make sure that your drilled hole is slightly larger than required. Doing so will allow screws placed in those holes to move freely without exerting unnecessary stress on the plastic material. How Do You Drill a Hole in Plastic Without a Drill?

Hex shank - A hexagonal-shaped shank used in screw guns or electric screwdrivers with a hammer mode. Of course! The material of the bit itself. Most can be made from high-speed steel (HSS), tungsten carbide, or cobalt. You’ll want to make sure you choose a metal that will last long enough to do the job. Does Size Matter?The length of the drill bit concerning its diameter. The longer the drill bit, the more surface area it has to bore into your project. A more extended drill bit will require more time and force to bore through a material, but it will ultimately be faster. FAQs What Type Of Drill Bit Is Best For Plastic?
