Have you ever wondered if you could cut wood with an angle grinder? Well, the answer is yes, you can! However, it’s important to understand how angle grinders work and how to use them safely when cutting wood. In this article, we’ll discuss the ins and outs of using an angle grinder for woodcutting, from understanding the right blade types to the essential safety tips. So, let’s dive in and explore the world of woodworking with angle grinders.

What is an Angle Grinder?

An angle grinder is a versatile power tool typically used to grind, cut, and polish various materials. This handheld tool features a high-speed rotating disc, commonly referred to as a grinding wheel or a cutting wheel, that can be attached to the motor-driven spindle. Its powerful motor can generate rotational speeds ranging from 4,000 to 12,000 revolutions per minute, allowing the tool’s disc to slice through metal or abrasive surfaces with ease.

Angle grinders are available in both corded and cordless variants, each with its own advantages and disadvantages. Corded angle grinders generally provide more power and a constant flow of energy, making them practical for heavy-duty tasks. However, cordless models offer increased mobility and flexibility, as they do not require a power source while in use, making them convenient for working in tight spaces or remote locations.

One of the unique features of angle grinders is their adjustability, allowing users to choose the appropriate level of speed and power for each job or material being worked on. The tool’s side handle, adjustable wheel guard, and various blade or wheel attachments enable users to perform a wide range of tasks: from smoothing out rough surfaces and removing rust to cutting through metal, stone, or ceramic tiles.

Although angle grinders are primarily designed for working with metals, they can be repurposed to cut wood, given the correct blade type and safety precautions are considered – which will be discussed in the later sections of this article.

Why use an Angle Grinder for Cutting Wood?

You may be wondering, why would you want to use an angle grinder for cutting wood instead of traditional tools like a jigsaw, circular saw, or bandsaw. To answer that, it’s essential to understand some of the benefits an angle grinder can bring to your woodworking projects.

Firstly, an angle grinder is incredibly versatile. With the right attachments and blades, you can use this handy power tool to cut, grind, sand, polish, and even sculpt various materials, including wood. This versatility means you save time and money by using just one tool for different tasks, rather than having to buy separate tools for each job.

Another advantage of using an angle grinder for cutting wood is its ability to make clean, precise cuts, even in tight or difficult-to-reach areas. The compact size and maneuverability of the angle grinder allow you to cut intricate designs or shapes that may be challenging with larger saws. This feature also comes in handy in situations when you’re working with reclaimed wood or lumber with multiple knots and imperfections that a regular saw might struggle with.

Additionally, an angle grinder provides excellent control over the speed and depth of the cuts you make. This control is particularly useful when working on projects that require detailed, intricate work or when you need to make adjustments to your cuts on the fly.

Finally, using an angle grinder can actually be safer for certain types of cuts, like plunge cuts or notching, compared to other tools. Some types of saws can bind or kick back when making these hard-to-do cuts, whereas an angle grinder can make them much more manageable and risk-free.

Using an angle grinder for cutting wood can offer several benefits compared to traditional methods. The combination of versatility, precision, and safety make this power tool a worthy addition to your woodworking arsenal.

Understanding Blade Types for Cutting Wood

To effectively cut wood with an angle grinder, it’s crucial to understand the different types of blades available and choose one designed specifically for the task. The type of blade you select will have a direct impact on the quality of the cut and the overall safety.

Carbide-tipped blades are the most popular choice for cutting wood with an angle grinder. These blades are made of a hard material, usually tungsten carbide, that retains its sharpness for a long time. Arbor-mounted blades, also known as flap discs, are another popular option. These discs have several layers of abrasive flaps, with each layer gradually wearing away to expose a new, sharp-cutting surface. This design results in a smooth, clean cut and reduced risk of the blade becoming dull or damaged.

Another versatile blade type is the chainsaw wheel or carving disc. It resembles a miniature chainsaw with a round disc that fits onto the angle grinder. These blades are specifically designed for precise, detailed carving in projects like woodworking or sculpting.

To correctly cut wood with an angle grinder, it’s essential to use the right blade. Avoid metal-cutting or masonry blades, as these can cause the wood to splinter or even catch fire due to the excessive heat generated.

Additionally, look for blades marked as “For Wood Only” to ensure they are specifically designed to handle the material. These blades usually come with a lower tooth count, which facilitates smoother cuts and cleaner edges in the wood. Always double-check the blade’s compatibility with your angle grinder and ensure that you fasten it securely to avoid accidents.

Safety Tips for Using an Angle Grinder on Wood

While angle grinders can be incredibly helpful when cutting wood, it’s important to prioritize safety when using them for this purpose. Here are some practical safety tips to keep in mind.

First and foremost, always wear proper protective gear, which includes safety glasses, gloves, ear protection, and a dust mask. Remember that you’ll be dealing with high-speed spinning blades, flying debris, and loud noise as you cut, so equipping yourself with adequate protection is crucial.

Secondly, ensure the angle grinder and blade are in good working condition. Inspect the equipment for any signs of damage or wear and ensure that the blade is properly attached and secure before you begin cutting.

Pay attention and use both hands to hold the angle grinder to maintain stable control during your cut. Always stand to one side, rather than directly in line with the blade, to avoid any potential kickback that could result in injury.

Disconnect the power source, whether it’s a battery or an electrical cord, when you’re changing the blade or making any adjustments to the angle grinder. This step is essential in preventing accidental starts that could cause serious harm.

Lastly, work in an environment with proper ventilation, as cutting wood often produces dust and airborne particles that can be harmful when inhaled. Following these safety precautions will help ensure that your woodworking project remains a fun and fulfilling experience.

When it comes to selecting the right angle grinder attachments for cutting wood, there are several options to choose from. This part of the article will discuss some recommended attachments that can make cutting wood with an angle grinder easier and more efficient.

First and foremost, you’ll need a blade designed specifically for cutting wood. A popular choice among DIY enthusiasts and professionals alike is the carbide-tipped wood cutting wheel, which is both durable and effective in cutting through various types of wood, including hardwood and plywood.

Another option is the chain saw disc, often referred to as a wood carving disc. This attachment features a circular saw chain wrapped around a metal disc, providing aggressive cutting power for rapid material removal. This type of disc is especially great for carving, shaping, and sculpting wood projects.

A third attachment you may want to consider is the flap disc, which uses overlapping abrasive flaps to grind and finish wood surfaces. This attachment is ideal for tasks such as sanding, deburring, and blending, offering a more controlled approach to material removal than the more aggressive chain saw disc.

Lastly, a wire brush is a useful attachment when working with wood. This accessory is perfect for cleaning, polishing, and removing paint or rust from wooden surfaces.

Regardless of the attachment you choose, make sure to properly install and securely tighten it to the angle grinder, following the manufacturer’s instructions, to ensure your safety and the success of your project.


While it’s not the most conventional method, using an angle grinder to cut wood is indeed possible. By selecting the appropriate blade attachments and following important safety guidelines, you can achieve precise and clean cuts on wood. However, it is imperative to weigh the advantages and potential dangers before deciding if an angle grinder is suitable for your wood-cutting project.
