However, there are also 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 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. When utilizing Angle Grinder for Cutting Wood, a lightweight material, a tiny change in posture, such as simply bending your wrist, might cause the grinder to dramatically shift direction. 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.

Tips and Tricks to Avoid Mistakes

While using an angle grinder for cutting wood, however, the least you can do is to always wear the proper PPE, such as safety goggles, ear protection, and cut resistant gloves, which are the absolute least minimum when working with a grinder. Keep in mind that the guard should never be removed unless the power supply is disconnected. When cutting any material with a grinder without a protection, you might end up in the hospital.

  • 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 using an angler grinder to cut wood is to go slow and 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.
