But if you want to undertake this task, you must first understand how to use an angle grinder for cutting wood and which blades (discs) to use. In the next section, we will talk about the dangers of using an angle grinder for wood cutting.

If you intend to use an angle grinder for small trimming or little jobs select proper cutting discs that are dedicated to wood. Cutting wood with an angle grinder should be considered a last-ditch attempt that should only be used if you don’t have any other options.

I did that once, using a 1/16th 22 degree tapered bit. I selected the objects I wanted to chamfer, set it around 0.003 outside offset and set the depth around 0.008 ish? When creating the toolpath I selected the tool profile of a straight 1/8th inch bit for speeds and feeds. You will need to decide how much you want to remove and set your dimensions accordingly, but it will work. You can control the angle by the amount of offset and depth.

Now that we have gone through some of the must-know safety tips when it comes to cutting wood with angle grinders, let’s talk about the steps for accomplishing this task in detail:

Before installing the blade, make sure that the grinder is not turned on and that it is unplugged. Install the blade using the instructions that come with your angle grinder and the disc.

An angle grinder has its purpose if you’re simply seeking to cut little woodcuts (like the edges of trim) or carve portions of wood. However, either a three-tooth wood-cutting disc for angle grinders or a wood carving disc should be used.

Carving, sanding, and shaping are all operations that angle grinders excel at. You can shape wooden materials with a wood carving disc attached to your angle grinder.

I am aware, but I believe I understood the OP’s intent. My example was simply an exaggeration of what I believe to be his intended outcome.

• Quick change of disc guard that allows the user to place the guard in different working positions• Easy and fast carbon brush changing mechanism• New locking pin system for easy and fast disc changing and safety mechanism• Anti-dust switch which reduces dust penetration, especially in masonry working conditions

Having a variety of chamfer tools, I’ve never used a ball. But I don’t see why you couldn’t do it using a 2d profile operation. Use offset/stock to leave and appropriate DOC. Instead of doing any math, I’d just open up a sketch in the design tab and draw a sketch with cutter diameter and your chamfer details.

When using an angle grinder for cutting wood which is an exceptionally lightweight material, a tiny change in posture, such as simply bending your wrist, might cause the grinder to dramatically shift direction.

• Ronix 3210 Mini Angle GrinderOur customers love this power tool because of its strong 2400W motor, 8000RPM no-load speed, 180mm wheel diameter, and ergonomic features. To turn it on, all you have to do is plug it in and press the anti-dust button.

This should step down 0.1mm from the surface and step in to the contour by 0.1mm leaving an approximation of a 45-degree angle. You can adjust the ‘stock to leave’ value from there if it is too much or too little of a chamfer…

Choose a wood carving disc for this tool that will operate on both soft and hard wood. A disc with the strength required for woodworking, as well as the proper form and design to undertake woodcutting operations with ease.

There could be advantages to using an angle grinder for carving, shaping, and sanding, but these tools are hard to control and you must always be completely focused and aware of the grinder’s limitations in contrast to other tools.

• Professional heavy-duty 2400W powerful motor that enables high performances• 3 positions anti-shock ergonomic side handle, minimizes vibration and reduces fatigue during long time working• Rotary main handle which accelerates working in different angles and improves user comfort and control• Soft start switch system that ensures the safety of operation• Direct airflow system which cools the motor for more reliable performance and higher overload capabilities• NSK anti-dust ball bearings which ensure the long lifetime of the motor and make it work more smoothly

Technically yes, but you should always use the dedicated blades for cutting wood. Even then, it’s dangerous! In short, we don’t advise it! Why don’t you use circular saws or jigsaws?

Again, we need to add that cutting wood with angle grinders is not a good idea and not safe generally. Of course, it is possible but we recommend that before undertaking this task, you read the section about safety concerns. When using these tools to do this particular task it is more necessary to ask yourself “How NOT to do it?” as this task can go wrong in a lot of different ways that could potentially harm you, so again reread the section about safety.

When it comes to using an angle grinder for cutting wood, the correct kind of blade is required. So, let’s look at a few alternatives for the greatest wood-cutting blades.

Thanks a lot for all the response guys. I think I’ve gotten it to work with a 2D contour now. Next stop is a test run, which I should have time for in a week or two.

When this happens, your response time may be insufficient to reverse the virtually immediate change, and you may find yourself with an out-of-control grinder running at 15,000 RPM. Plus, most grinders don’t have an electronic brake and are sluggish to stop spinning, and I’m guessing you don’t want to get in the way of an enraged grinder flying through space and time.

Now that you have gone through all these steps, you can start to cut wood with the angle grinder. Turn on the grinder and let it reach full speed before approaching the workpiece. Gently lower the spinning blade onto the marked cut line.

@MindlessCorpse So you “tricking” Fusion 360 to thinking it was a flat endmill? Why not just choose a ball endmill? Did you use 2D contour?

Measure twice and cut once. Right? You should always be attentive to details, especially in this task. Angle grinders are not very precise tools. You need to mark your cut on the wood to avoid any mistakes.

We are going to repeat some of the points we made in the other sections about safety when cutting wood with angle grinders:• Always use the dedicated type of disc (blade) for this task! And nothing but the dedicated types of discs. Using an angle grinder on wood without the specialized blades is extremely dangerous! Also, make sure that the speed and size of the disk you are using match your angle grinder.• Always wear proper PPE (Personal Protection Equipment) which includes safety glasses or face shields, hearing protection, gloves, dust masks, or respirators.• Make sure that the environment you’re working in is safe and secure. Always have a fire extinguisher nearby and make sure there is no chance of slippage.• Employ the right pose and technique when cutting wood with angle grinders to minimize any unintended risks including the blade moving towards you and injuring you in case of the tool kicking back.• Safety check the disc! Meaning check the disc for any damages or if it has reached the end of its expiry date!

The first thing is that there are a lot of safety precautions to note when working with angle grinders in general. There are additional safety precautions when it comes to cutting wood with angle grinders. Before you bring out your trusty angle grinder to maul that would-be piece of lumber, consider all the tips and notes that will be discussed in this article.

Hold the angle grinder with both hands. One hand should be on the main handle and the other should be on the side handle. Position yourself in a way that you can maintain a stable stance for maximum control.

Not knowing about the potential hazards of using an angle grinder for cutting wood may result in untreatable and permanent damage.

• The first mistake to avoid is driving too quickly. When performing something potentially harmful, it’s natural to want to get it over with as soon as possible. In this case, you could wind yourself paying a high price for it.• One of the most crucial aspects of cutting wood with angle grinders is to go slow and be careful with your motions. As a result, take your time. If you hurry the job, you risk receiving a kickback from the grinder, which might result in serious injury.• Keep in mind that you’ll almost certainly need to become used to cutting at an angle. Your inclination will be to cut straight down, but this will increase your risk of harm. Instead, try making each cut at a small slant. The angle will perform better and cut more accurately because this tool is designed to carve wood rather than cut it.

Yes is the quick and idiotic response. However, for cutting wood, angle grinders are not ideal. First of all, you should never cut wood with regular angle grinder cutting discs. A lot of professionals advise against using the angle grinder for wood completely, especially for beginners.

There are significant dangers associated with using an angle grinder for woodcutting, so understanding what to expect can help you stay safe. What is the reason behind this? Because cutting a flammable material like wood with an abrasive blade on a grinder might result in disaster. Aside from the obvious one, there is also another potential hazard associated with using Angle Grinders for Cutting Wood.

• GRAFF SPEEDCUTTER 4 1/2 Wood Carving Disc for Angle GrinderIf you want to cut wood with angle grinders, this is one of the most popular blades on the market. These blades can be used to cut wood, laminated flooring, parquet (hardwood), plasterboard, plastic, and maybe even aerated concrete. The GRAFF Speed-cutter woodworking disc features only three teeth, allowing the angle grinder to achieve an acceptable level of radial resistance at a rapid rotation rate.

You should now turn off the grinder completely. Afterward, you should inspect the cut to make sure that it is smooth and precise.

Used Carbide Create and Carbide Motion And I have used different bits than chosen in tool paths for varying reasons. Yes to the contour path and CC does not yet support tapered geometry. I am thinking that you want to get rid of the “stark” look of the 90 degree angle at the top of the cut. Maybe it is called a chamfer, maybe not… I have used v-bits to try this before and did not care for the obvious flat angle, that rounded reverse dogbone (or whatever one wants to call it) seems to soften the look quite nicely, without actually being seen? sort of a finesse effect.

That does not mean, however, that using an angle grinder for wood cutting would be the optimal option for the situation. Although an angle grinder is useful for little projects, you should think hard before using it on a major project.

I know it’s not technically a chamfer when using a ball nose, but it’s such a tiny chamfer I’m planning to make, that I don’t think it’ll matter.

As you can see, the debate over whether or not angle grinders should be used to cut wood is not simple. The reason for this is that this tool may be too strong for most wood products, increasing the risk of harm from backlash. However, you do have options when it comes to cutting wood with a grinder, as you can simply replace the disc with a three-tooth disc for minor projects.

Using an angle grinder for cutting wood raises several obvious safety hazards. However, if you take the proper precautions, use the proper three-tooth cutting disc, and just need to trim a few corners here and there, an angle grinder is a feasible alternative.

@holgersindbaek I am doing this from memory so use caution and test on scrap first, but I am pretty sure the following will do what you want. Make sure the ball endmill is set up as a ball endmill in the tool manager. I would then: 1.) use 2d contour, 2.) then in the ‘heights’ tab set your ‘top height’ to be ‘selected contour’ with a pos0.2mm offset and 3.) set your ‘bottom height’ to be ‘selected contour’ with an offset of neg0.1mm, and 4.) in the ‘passes’ tab set ‘stock to leave’, for both radial and axial, each to be neg0.1mm (make sure the box is checked). 5.) Do this to a test piece first, even with a generic extruded box model, on a piece of scrap to see if this does what is expected.

Because of its air-flow cooling mechanism, working long hours will not be a problem for the 3210. Three-position anti-vibration side handle, rotating main handle, quick-change disc guard, and locking pin system are among the features.

I think the other posts suggesting the same sort of thing with a V-bit are correct. Calculate an offset path and do a contour pass, but put a v-bit in. It doesn’t matter what Fusion360 thinks it is so long as you can generate a tool change to stick the V-Bit in.

People have been utilizing circular saw blades with angle grinding machines for woodworking for many years, which is dangerous! An angle grinder’s large number of teeth paired with its rapid RPM rate frequently results in finger amputations and other serious accidents!

@Lowbrowroyalty I’ll give it another go. Would you chose a ball end mill as the tool or would you use a flat endmill and trick it into thinking it’s a ball endmill?

When attempting to create accurate miter cuts or ripping boards of wood, if you have access to a circular saw, table saw, or even a miter saw, you’d be better off going that route. Using an angle grinder on wood is not accurate at all and these tools are hard to control.

Rotating at high speeds might cause serious injury. Instead of attempting to use a standard blade, go for one of the wood-cutting blades for angle grinders mentioned below to help decrease the risk of an accident while keeping the smooth and precise aesthetic of your project.

Always move the grinder steadily along the cut line and maintain a consistent speed. Get a feel for the material and how it interacts with the grinder. Cut until you reach the end of the line.

Let’s start with the question of whether a normal blade can be used to cut wood. This is a common mistake made by novice users, and it is something you should avoid. Cutting with a normal blade is technically possible, but it is not safe at all and therefore you should never cut wood with angle grinders.

I know it’s not technically a chamfer when using a ball nose, but it’s such a tiny chamfer I’m planning to make, that I don’t think it’ll matter.

While using an angle grinder for cutting wood, however, the least you can do is always wear the proper PPE, such as safety goggles, ear protection, and cut-resistant gloves, which are the absolute minimum when working with a grinder.

A ball endmill is perfect for doing an inverse fillet… so a 3m inverse fillet for a 6mm endmill in a single contour pass at 3m below the top surface.

In a study conducted by a group of hand surgeons in Japan based on the records of 15 patients treated for angle grinder injuries between 2017 and 2018, it was proven that the lack of knowledge about the machine’s capacity was the main reason for these injuries.

I don’t think it should matter, but I haven’t tried it. I have my tools arranged by use and material in the library under a variety of different categories that don’t necessarily match the tool explicitly.

I just tested it. 2D contour, the profile to be chamfered selected, ball endmill selected. Used heights tab for final DOC, and negative stock to leave for final WOC. With the negative stock to leave, I think you’re limited to some percentage of the cutter diameter, probably something in the ballpark of 50%. You could add offsets, add sketch geometry, ect if you need more.

The grinder might rise and fly off the table you’re working on if something goes wrong. You might be badly injured if you rotate at high speeds. Instead of attempting to use a regular blade, you should seek one of the wood blades for angle grinders listed below to assist in reducing the chance of an accident while maintaining the smooth and accurate appearance of your project.

Keep in mind that the guard should never be removed unless the power supply is disconnected. When cutting any material with a grinder without protection, you might end up in the hospital.

Therefore, if we get back to the question here, can angle grinders also be used to cut wood? The best answer would be: Yes, of course, with a big caveat! You can cut wood with angle grinders, but only if you are using the proper wood-cutting disc for angle grinders because it has the strength and capability to do so.

Because of the density of the material, there is more resistance when using a high-speed power instrument like a grinder to create a cut on a piece of metal, or even when attempting to cut concrete with a diamond saw blade. With wood, however, this is not the case.

A heavy-duty angle grinder can easily cut through metal, masonry, and even concrete. But is it a good idea to use these tools to cut wood? Cutting wood with angle grinders is tricky. In this article, we will talk about all the reasons why.

I’ve been trying using 2D contour, flow trace and spiral, but with no luck. Am I overlooking something? Has anyone managed to chamfer using a ball endmill? Can you give an example?

As long a contour allows you to select a ball, which I imagine it should, just calculate the offsets for the chamfer. I typically use the stock to leave offset for simplicity, you can use a negative stock to leave offset. As mentioned above, the easiest way for me to setup these kinds of offsets is with a F360 sketch, which will provide you with dimensions, and the inspect tool for any queries.
