As you may already know, the angle grinder is one of the most popular power tools on the market. Isn’t that right? It is a product that is used both by professionals and by ordinary DIY enthusiasts who like to carry out repairs themselves at home. Because a high-quality angle grinder can effortlessly cut everything from metal to brick and concrete.
And with a range of powerful cordless angle grinders on the market, portability is just one of the great advantages of owning one of these favourite tools.
But while angle grinders are certainly a good power tool used by electricians, plumbers, HVAC technicians and weekend warriors, are they really a tool that carpenters or joiners would like to choose? Well, the answer’s pretty complicated.
The fact is that wood is a much lighter material than metal, which means that the use of aggressive tools such as angle grinders may not produce the results you originally expected. In fact, improper use of a wood grinder for sawing wood can cause serious injuries, which you want to avoid at all costs.
Of course, there are a few important points to consider before you decide to sharpen a silly sander into pieces that can turn into a piece of wood. We have studied this dubious subject in depth and found useful answers to the question of whether angle grinders can cut wood and whether or not you should be involved in this potentially dangerous activity.
Well, let’s see.
The biggest problem when sawing wood with an angle grinder is that you have to deal with a super powerful hand tool on a slightly sensitive material. This means that you may not have the control necessary to achieve the best results and may also increase the likelihood of a collision with potential injury. But why? The answer is very simple.
Once mounted on the angle grinder, a disc can rotate at up to 15,000 revolutions per minute, increasing the risk of major kickback and ultimately causing serious hand injury. If you’re lucky, you can do it, but why take the risk if there are better options, like a circular saw?
Although this is a fact, it does not exclude the possibility that certain types of wood are better suited for sawing with a sander. By the way, are you looking for a small woodcut or something more complicated? If you refer to the cutting edges, you will probably be fine as long as the angle grinder has its protection.
A material like plywood, for example, is certainly not something you want to use an angle grinder for! If you don’t want to end up with a face full of stitches or a paralysed hand, you better use other, more suitable tools when sawing plywood.
Is sawing wood with an angle grinder efficient? 1С8 1Д9
Yes, sawing wood with an angle grinder causes some safety problems, but if you take these precautions and feel that only the edges and smaller, heavier cuts of wood can be cut efficiently, is it possible to do this? The answer is an absolute yes! This has to do with the fact that it is virtually impossible to find a power tool that is more efficient than an angle grinder.
With cutting speeds of up to 15,000 rpm, any material is simple enough with sufficient patience. But why would carpenters recommend angle grinders if they’re not so sure?
Especially because without an angle grinder the whole process of cutting and shaping the wood is much more difficult. This tool is almost perfect for tasks such as thread cutting, grinding and forming, which explains its high market value.
Since it can carry out heavy work for short periods of time, you should be aware that safety goggles and PPE equipment are important for your safety when working with the grinder. In fact, all power tools must be handled with care. But when it comes to chopping machines, more than 5,000 injuries are reported annually in the United States, so working with a chopper has to be done with great care.
At the same time, you should be aware of the nozzles that make this process easier and safer for you. Never remove the grinder’s protective cover when the power supply is not switched off. The use of an unguarded chipper when cutting a material such as wood can give you more manoeuvrability, but frankly it’s not worth it.
In the end, it depends on what you want to achieve. Thread grinding discs, threaded wheels and patch rims are very important, especially when it comes to wood in everyday life. But when it comes to sawing wood, I think it always depends on the wood, the sawing and the blade used.
Can a metal cutting disc be used on wood? 1С8
In short, the answer is yes. But this is not ideal, and most experts do not recommend the use of a metal grinder for cutting wood. Why is that? Using a grinding knife on a grinder to cut flammable materials such as wood can lead to tragedy.
In addition to this obvious reason, there is another potential danger associated with the use of a sander for sawing wood, namely kickback.
If you use a high-speed tool such as a grinder to grind a piece of metal, or even if you try to grind concrete with a diamond saw blade, you will gain greater strength due to the density of the material. It’s not about the tree. A slight change in position due to a slight twisting of the cut can cause a sudden and radical change in the reaction force of the grinder on the workpiece.
When this happens, your reaction time will not be fast enough to handle an almost instantaneous change and you now risk an uncontrolled rotation of the grinder at 15,000 rpm with a metal cutting disc flying over the workpiece. Besides, grinders usually don’t have electric brakes, and they turn slowly until they stop, and I don’t think you want to get in the way of an evil grinder floating in space and time.
So yes, using a sander with a metal cutting blade to sand the wood is not a good idea.
What is the safest alternative to fast wood cutting? 1С8
It all depends on the tool you have access to, but you can use a circular or circular saw, or even upgrade the blade of an existing angle grinder to effectively cut any wood material. There is a saw blade that can be adapted to the grinder and uses only three teeth instead of a much larger number of teeth using a cross or a tear-off block.
As long as the rotation of the blade coincides with that of the grinder, you can easily cut wood with a triple toothed angle grinder. This type of blade is designed for high speeds, and thanks to the economical construction of the trident you have a minimal risk of possible kickback.
As mentioned earlier, this type of saw blade is relatively new on the market and can be considered as a special saw blade, so it may be somewhat difficult to find at your local hardware store. The best way to find one of these unique saw blades is to search the internet among the many visits to the PornHub, or reluctantly go to the front door to find that mysterious saw blade. Or you could just try the Amazon…
As you can see, the discussion about whether or not to use angle grinders for sawing wood is not that simple. This is because these tools may be too powerful for most wood materials, increasing the risk of injury from possible kickback.
When using a sharpener, however, you have the choice, because you can easily change the saw blade into a three-tooth saw blade.
Although we believe that the use of an angle grinder for threading, forming and grinding has certain advantages, it is necessary to concentrate fully and understand the limitations of using the angle grinder compared to other tools. If you have other solutions, such as a circular saw, table saw or even a circular saw, it is best to go in that direction when you are trying to make precise circular cuts or when you are trying to tear wood panels.
