This power tool can help you finish, sculpt, and shape workpieces with ease. It’s particularly useful in confined spaces and getting into nooks and crannies, thanks to its size, making it more useful for so many projects.
However, a die grinder won’t be as functional as it can be without the right type of cutter. As this power tool requires an additional attachment to get various tasks done, you’ll need to look into the different kinds of cutters that you can use with a die grinder.
There are actually several available and each one has its own specific purpose. Getting to know the different kinds of cutters will help you get more use out of a die grinder.
Which Type of Die Grinder Cutter Do You Need?
The great thing about die grinders is that they use a ⅛” collet as an accessory spindle instead of a Jacobs chuck. This makes this power tool more flexible and easily compatible with a wide range of accessories.
Tools with a 1/8″ diameter shaft can be used, as long as they are made for the RPM your unit is capable of producing. As for the various types of cutters, you have a few to choose from. These are a few examples:
- Drill bits are small cutting tools that come in a wide range of designs, all of which are designed to create holes in various materials. They’re often used in drills, but they can also perfectly fit a die grinder.
- Grind stones are basically stones mounted on a screw that are designed to help you grind and file surfaces. They’re often made out of aluminum oxide, alox, and carbide. You can use them for “frosting” or engraving larger areas of glass.
- Cutoff discs are useful if you need to lop off a section of your workpiece without having to use a separate tool. They’re great for when you’re working with an intricate project and you need to trim something in a tight corner. Often made with high-grade steel, they can be quite dangerous to use if you’re not fully familiar with how it works.
- Sanding drums are basically abrasive belts that are mounted on a metal screw. They are often used for finishing projects and polishing hard to reach areas.
- Rasps are designed for carving purposes with the help of a die grinder. They’re very coarse, but they can easily shape softer materials like plastic, wood, and soft metals.
- Flap wheels are also commonly used for finishing and polishing metal works but a lot of experts prefer them over sanding drums as they don’t leave a specific pattern on the surface. Due to its design, it’s also more durable than other sanding cutters, as you can continuously use it even as the flaps erode.
- Sanding discs are flat disc attachments that you can use to flatten welds and ready the project for painting. It’s easy to use, but you might need to replace it a few times before you get to finish a large area.
- Spiral saws are basically small bits that can do some sideway cutting. It’s ideal for trimming plastics and other thin and soft materials.
- Diamond coated engraving bits have their tips reinforced with diamond so they can easily create marks in very hard surfaces like glass. They come in different shapes to suit various kinds of engraving.
- Metal wire wheels are great for cleaning surfaces. They can remove paint, rust, scale, and corrosion without damaging steel projects. It can also help raise grain in wood but isn’t ideal for concrete.
- Nylon brush wheels are also designed to clean workpieces. However, this accessory is made with plastic bristles, so it’s only ideal for removing softer materials like loose paint. It’s also ideal for more delicate projects as its soft bristles won’t scratch your workpiece’s surface.
- Diamond cutoff discs are high-end alternatives for cutoff discs that tend to shatter after a few uses. The diamond options are a whole lot sturdier and last longer so you don’t need to replace them every so often.
- Polishing pads are designed to help you clean projects more thoroughly. They’re often made from cotton, felt, and other materials. They also add a swirling detail to metal projects. Used with screw mandrels, this die grinder accessory also requires the use of a polishing compound.
