As anyone who has used a rotary tool will attest, having the right bit for the job can make all the difference in terms of both speed and precision. Whether you’re looking to cut through metal or plastic, knowing the right rotary tool bits and their uses will help you get the job done quickly and efficiently.
You can’t just use any rotary tool bit for every job, however. The type of material you’re working with will dictate the type of rotary tool bit you need to use. Here’s a guide for you!
What Are Rotary Bits and What Do They Do
Before we get into the different types of rotary tool bits and their uses, let’s first answer what rotary tool bits are and what they’re used for. It will help give you a better understanding of using rotary tool bits for different purposes.
A rotary bit is a cutting tool attachment that can be used with a rotary tool, such as a Dremel. Rotary bits come in all shapes and sizes, and each one is designed for a specific purpose.
Each rotary bit is designed to cut through a specific material, whether that’s metal, plastic, wood, or something else. In most cases, rotary bits are made out of high-speed steel (HSS), which is a type of steel that can withstand high temperatures without losing its shape.
They can also be made out of carbide, which is an even stronger and more durable material. However, carbide rotary bits are more expensive than HSS rotary bits. But either way, rotary tool bits are designed to make quick work of whatever material you’re working with.
22 Different Types of Rotary Bits and Their Uses
When doing any rotary tool work, it’s important to use the correct rotary bit for the job. It will make the job faster and easier and help you avoid damaging the material you’re working with. So here are some of the most common rotary bits and their uses:
➣Spade Drill Bits
If you are looking to make a quick and easy hole in wood, you will want to use a spade drill bit. Spade drill bits have a wide, flat tip that quickly digs into the wood, making a large hole with minimal effort. Just be sure not to use a spade drill bit on any other material, as it will damage the rotary bit and potentially the rotary tool itself.
➣Brad Point Drill Bits
If a spade drill bit is the best rotary tool bit for wood, then a brad point drill bit is the best rotary tool bit for metal. That’s because brad point drill bits have a sharp, conical tip that quickly pierces through metal without causing any damage to the rotary tool or rotary bit.
➣Plug Cutter Bits
Another type of bit you can use for drilling holes in wood is a plug cutter. Plug cutters are basically large, cylindrical rotary bits that can quickly drill a hole in wood. However, they are not meant for use on any other material. It’s also important to note that plug cutters require a rotary tool with more power than a standard rotary tool, so be sure to use the correct rotary tool for the job.
➣Step Bits
If your project requires you to drill many holes, you will want to use a step bit. Step bits have a series of different-sized cutting tips that allow you to quickly drill a hole in any material. And because they can be used on any material, step bits are one of the most versatile rotary tool bits you can use.
➣Countersink Bits
Unlike other rotary bits, countersink bits are not used for drilling holes. Instead, countersink bits are used for enlarging the top of a drilled hole. It is often done so that a screw can be inserted into the hole without the head of the screw sticking out.
➣Bullet Point Bits
If versatility is what you’re looking for, then bullet point bits are the rotary tool bits for you. Bullet point bits can be used on any material and are great for various tasks, such as drilling holes, enlarging holes, countersinking, and even engraving. They will give you clean and precise results every time.
➣Twisted Drill Bits

They also have cutting edges that quickly and easily cut through glass. They are made specifically for drilling through glass, so be sure to use the right rotary tool bit for your project.
➣Rasp Bits
If you want to polish, burnish, or carve wood, you will need a rasp bit. It has a cylindrical shape with a sharp, abrasive edge that quickly and easily removes material. You can use a rasp bit to remove small amounts of material or to create intricate designs. And if you’re worried about damaging the wood, don’t be. Rasp bits are designed not to damage the wood.
➣File Bits
Filing is the process of removing material from a surface to create a smooth, finished look. Unlike rasping, which removes small amounts of material, filing removes large amounts of material. It has a sharp, cutting edge that quickly and easily removes material. File bits are available in various sizes, so be sure to choose the right size for your project.
➣Engraving Bits
Engraving is the process of carving a design into a surface. And the best way to do that is with an engraving bit. It has a sharp, pointed tip that quickly and easily pierces through the material. And it has a cutting edge that quickly and easily cuts through the material.
