Using a woodcutting blade on an angle grinder is frightening, and you must always avoid it and invest in a safer tool like a circular or jig saw. Why is it unsafe? Can you cut wood with an angle grinder, which we will thoroughly discuss in this article?
Before we discuss whether we can cut wood with an angle grinder, we have to understand what an angle grinder is.
You can also watch my video on this topic.
What is an Angle Grinder?
An angle grinder is a handheld power tool with a rotating abrasive disc or wheel. Due to its versatility for cutting, grinding, polishing, and shaping operations, it’s commonly used for construction, metalworking, and fabrication tasks.
Why Is It Unsafe to Use an Angle Grinder for Wood Cutting?
This handheld tool is designed for a more rigid material, and here are some reasons that make it unsafe for woodworking.
High Speed
Angle grinders typically operate at very high speeds, often exceeding 10,000 RPM (Revolutions Per Minute), which is madness! This high-speed rotation is well-suited for cutting through metal or concrete but can be excessive for wood. This unwanted speed can cause a rough cut, burn wood, and splinter it.
Blade Type
Compared to metal and concrete, wood cutting blades are more aggressive and apply higher resistive force on the wood. That’s why you’ll get a kickback if your hand deflects slightly.
DO NOT ATTEMPT TO INSERT A REGULAR WOODCUTTING BLADE INTO AN ANGLE GRINDER, AS IT CAN RESULT IN SERIOUS INJURY. THIS MUST BE STRICTLY AVOIDED AT ALL COSTS!!!
There are some special blades designed for wood cutting with an angle grinder, which we will discuss below.
Lack of precision
It’s a handheld tool designed for heavy-duty tasks and may not provide the high accuracy and control required for woodworking.
Safety Concerns
This tool can generate a significant amount of wood chips, dust, and debris, which poses health hazards if not properly managed.
Now you know the danger of working with an angler grinder, especially for woodworking. Now, let’s come to our essential question.
Can You Use a Grinder to Cut Wood?
Yes, you can undoubtedly cut wood with an angle grinder. Here are some methods to turn your angle grinder into a less dangerous woodcutting machine. Again, I warn you: if you don’t know what you’re doing, please buy a regular saw; it’s very DANGEROUS!
Method 1: SCR Voltage controller (Complementary Method)
As I mentioned, angle grinders usually work at higher RPM, which is one of the significant safety concerns when using them for woodworking. The SCR voltage controller can slow your angle grinder’s speed and enhance safety. This method provides finer control, so you can use your angle grinder more efficiently for different purposes, like sanding, polishing, or cutting.
However, if your angle grinder already has a variable speed option, you should see the following method.
Method 2: Wood Carving Disk
Some particular types of wood carving disks are available for angle grinders. These disks have less aggressive and widely gaped teeth, which allows cutting through wood with less resistive force. However, precision shouldn’t be expected with this method because the cuts are rough.
Method 3: Chain Saw Attachment
As its name suggests, this accessory can turn your angle grinder into a chainsaw. It allows you to cut through thick branches or small logs, making it perfect for outdoor projects like pruning trees or processing firewood. Please follow the manufacturer’s safety guidelines.
Method 4: Circular Saw Attachment
Compared to handheld operation, using a circular saw attachment makes the angle grinder a much safer choice for woodworking. It also provides much more accurate cutting because you can use a regular wood cutting blade. Please slow down your angle grinder with a built-in speed controller or use an SCR controller, as discussed in method 1.
Tips for Using Accessories:
Safety First: Regardless of the accessory you use, always prioritize safety. Please wear appropriate safety gear, including eye and ear protection, gloves, and dust masks, especially when working with woodcarving disks or chain saw attachments.
Read the Manual
Each accessory has its instructions and guidelines. Always read and understand these instructions thoroughly before use.
Practice and Patience
When using new accessories, take the time to practice on scrap wood to get a feel for how they work. Mastery often comes with patience and practice.
Maintenance
Keep your accessories clean and well-maintained. Regularly inspect the chains on chain saw attachments and ensure they are sharp and properly tensioned.
Secure Your Work
Like standard woodcutting, always secure your workpiece using clamps or a vice to prevent movement while cutting.
Adjust Speed Accordingly
If you’re using a variable speed angle grinder with an SCR voltage regulator, adjust the speed to match the task. Lower RPM is generally better for woodcutting and carving.
Pro Tips – To Use an Angle Grinder on Wood
- Keep your hands and body away from the cutting area to avoid accidents.
- Be mindful of kickback, which can occur if the blade binds in the wood. Maintain a firm grip and be prepared for sudden jerks.
- Work in a well-ventilated area to minimize dust inhalation.
- Keep a fire extinguisher nearby when cutting treated or exotic wood, as sparks can ignite.
So, Should You Use an Angle Grinder for Wood Cutting?
Finally, you know the answer: Can an angle grinder be used to cut wood, and what risks are associated with it? Please follow all the instructions and safety precautions carefully.
There are some positive sides to using an angle grinder for wood cutting, especially when clubbed with a carving disk. You can make some intricate and artistic cuts and shape wood seamlessly.
