Which Direction Do You Cut With an Angle Grinder?

An angle grinder is a versatile power tool that can be used for various purposes, such as cutting metal, concrete, tiles, bricks, and wood. It can also be used for grinding, sanding, polishing, and sharpening different materials. However, using an angle grinder requires some skill and caution, as it can be dangerous if not handled properly. One of the most common questions that beginners have is: which direction do you cut with an angle grinder?

The Correct Answer: Cut Away From Yourself

The correct answer is that you should always cut away from yourself when using an angle grinder. This means that the blade or disc should rotate in the opposite direction of your body movement. This way, you can avoid the risk of kickback, which is when the blade or disc gets stuck in the material and jerks back towards you. Kickback can cause serious injuries, such as cuts, burns, or even amputation.

Cutting away from yourself also helps you to have more control over the angle grinder, as you can apply steady pressure and guide the tool along the desired line. Cutting towards yourself can make the angle grinder harder to maneuver and more likely to slip or wander off the mark. Additionally, cutting away from yourself reduces the amount of dust and debris that flies towards your face and eyes, which can impair your vision and cause irritation.

How to Cut With an Angle Grinder Safely and Effectively

Knowing which direction to cut with an angle grinder is not enough to ensure a safe and successful project. You also need to follow some other tips and precautions, such as:

Wear proper protective gear, such as gloves, goggles, ear plugs, and a dust mask. Angle grinders can produce sparks, noise, and dust that can harm your skin, eyes, ears, and lungs.

Choose the right blade or disc for the material and the task. Angle grinders can use different types of blades or discs, such as abrasive, diamond, or carbide. Each one has its own advantages and limitations, depending on the hardness, thickness, and shape of the material. For example, abrasive discs are good for cutting metal, but not for cutting concrete or stone. Diamond discs are good for cutting hard materials, but not for cutting wood or plastic. Carbide discs are good for cutting wood, but not for cutting metal or concrete.

Check the condition and alignment of the blade or disc before using it. Make sure that the blade or disc is not cracked, chipped, or worn out, as it can break or shatter during operation. Also, make sure that the blade or disc is securely attached and aligned with the spindle and the guard of the angle grinder. A loose or misaligned blade or disc can cause vibration, wobbling, or jamming, which can lead to kickback or injury.

Mark the line of the cut on the material before starting the angle grinder. This will help you to follow the desired path and achieve a precise and clean cut. You can use a pencil, a chalk, or a tape measure to mark the line of the cut. You can also use a clamp, a guide, or a fence to hold the material in place and support the angle grinder along the line of the cut.

Start the angle grinder and let it reach full speed before touching the material. This will prevent the blade or disc from snagging or skipping on the surface of the material. Hold the angle grinder firmly with both hands and position it at a 90-degree angle to the material. Then, gently lower the blade or disc onto the material and start cutting away from yourself. Do not force the angle grinder or push it too hard, as this can cause overheating, binding, or kickback. Let the tool do the work and move it smoothly and steadily along the line of the cut.

Stop the angle grinder and let it stop spinning before lifting it off the material. This will prevent the blade or disc from hitting or scratching the material or the workbench. Also, do not touch the blade or disc until it cools down, as it can be very hot after use. After finishing the cut, inspect the material and the angle grinder for any damage or defects. If necessary, you can use a file, a sandpaper, or a polishing pad to smooth out the edges or the surface of the material.


An angle grinder is a useful tool that can help you to cut various materials with ease and efficiency. However, you need to know how to use it correctly and safely, especially when it comes to the direction of the cut. Remember to always cut away from yourself when using an angle grinder, as this will prevent kickback and other hazards. Also, follow the other tips and precautions that we have discussed in this article, such as wearing protective gear, choosing the right blade or disc, checking the condition and alignment of the blade or disc, marking the line of the cut, starting and stopping the angle grinder properly, and inspecting the material and the angle grinder after use. By doing so, you can enjoy the benefits of an angle grinder without compromising your safety or the quality of your work.
