Wire mesh is a popular material in many DIY and construction projects. It is commonly used to make fences, cages, and other structures that require durability and stability. However, cutting wire mesh can be challenging, especially if you don’t have the right tools or technique. In this article, we will discuss how to cut wire mesh with an angle grinder, one of the most effective and efficient tools for the job.
Why use an angle grinder for cutting wire mesh?
An angle grinder is a versatile power tool that can be used for various cutting and grinding tasks. It consists of a motor, a handle, and a spinning abrasive disc or cut off wheel that can be attached to the spindle. The cut off wheel is specifically designed for cutting through metal and other tough materials, including wire mesh.
Compared to other cutting tools such as wire cutters, bolt cutters, and hacksaws, an angle grinder offers several advantages. First, it can make straight and curved cuts with precision and speed. Second, it can cut through thick wire mesh quickly and efficiently. Finally, it can be used to grind down sharp edges and smooth out rough surfaces after cutting.
What cutting disc to use for cutting wire mesh?
Choosing the right cutting disc is crucial for achieving clean and accurate cuts on wire mesh. The most commonly used cutting disc for wire mesh is a thin cut-off wheel. Thin cut-off wheels are designed to cut metal and other hard materials quickly and efficiently. They are available in various sizes and thicknesses, so it’s essential to choose the right one for your job.
When choosing a cutting disc, you should consider the following factors:
- Size:The size of the cutting disc you need will depend on the size of the wire mesh you are cutting. Generally, a 4-1/2-inch cutting disc will be sufficient for most jobs, but you may need a larger or smaller disc depending on the project’s scale.
- Thickness:The thickness of the cutting disc is also crucial. The thinner the disc, the faster it will cut, but it will also wear out faster. Thicker discs last longer but cut slower. For wire mesh, a thin cutting disc with a thickness of 0.045 inches is suitable.
- Material:Cutting discs are made of various materials, including aluminum oxide, zirconia alumina, and silicon carbide. Aluminum oxide cutting disc is suitable for cutting most metals, while zirconia alumina is more durable and suitable for heavy-duty cutting. Silicon carbide cutting disc is suitable for cutting non-ferrous metals and masonry.
Preparing the Angle Grinder
Once you have selected the right cutting disc, you need to prepare your angle grinder. Here are the steps to follow:
- Attach the Cutting Disc:Make sure your angle grinder is unplugged and that the cutting disc is the right size and type for the job. Loosen the nut on the spindle, insert the disc, and tighten the nut securely with a wrench.
- Adjust the Guard:The guard is a safety feature that protects you from flying debris and sparks. Adjust the guard so that it covers the cutting disc entirely, but does not interfere with the cutting process.
- Install the Handle:Most angle grinders come with a handle that attaches to the side of the tool. The handle helps you control the tool and reduces fatigue. Install the handle according to the manufacturer’s instructions.
Cutting the Wire Mesh
Now that your angle grinder is ready to go, it’s time to start cutting the wire mesh. Follow these steps:
- Mark the Cut: Use a permanent marker or chalk to mark the section of wire mesh you want to cut. Make sure the marks are visible and accurate.
- Secure the Wire Mesh:Secure the wire mesh to a workbench or another stable surface using clamps. Make sure the area you are cutting is supported and that the wire mesh cannot move during the cutting process.
- Turn on the Angle Grinder: Turn on the angle grinder and let the disc reach full speed before you start cutting.
- Start Cutting: Position the cutting disc at the beginning of the cut and slowly lower it onto the wire mesh. Apply light pressure to the angle grinder and let the disc do the cutting. Avoid forcing the disc or using excessive pressure, as this can damage the disc and increase the risk of injury.
- Follow the Mark:Follow the marked line with the cutting disc, moving the angle grinder in a straight line. Use a steady hand and keep the angle grinder at a consistent angle. If you need to make a curved cut, move the angle grinder in a slow, smooth motion.
- Check the Cut:Once you have completed the cut, inspect it to ensure it is clean and smooth. If the cut is rough or uneven, use a file or sandpaper to smooth it out.
Safety Tips
Cutting wire mesh with an angle grinder can be dangerous, so it’s essential to take the necessary safety precautions. Here are some tips to keep in mind:
- Wear Protective Gear:Wear eye protection, ear protection, and a dust mask to protect yourself from debris, sparks, and dust. Wear gloves to protect your hands from the cutting disc.
- Keep the Work Area Clear:Clear the area around the wire mesh of any flammable materials, liquids, or debris. Keep bystanders away from the work area.
- Use the Guard:The guard is designed to protect you from flying debris and sparks. Make sure it is adjusted correctly and use it at all times.
- Keep a Steady Hand:Keep a steady hand while using the angle grinder and avoid sudden movements or jerks. Use light pressure and let the cutting disc do the work.
- Allow the Disc to Cool:Cutting wire mesh generates heat, which can cause the cutting disc to wear out quickly. Allow the disc to cool periodically to extend its lifespan.
Conclusion
Cutting wire mesh with an angle grinder is a useful skill that can save you time and effort. With the right cutting disc and proper technique, you can make precise cuts quickly and efficiently. However, it’s important to take the necessary safety precautions to avoid injury or damage to the cutting disc. Remember to wear protective gear, use the guard, and keep a steady hand while cutting. If you follow these guidelines, you can cut wire mesh with an angle grinder safely and effectively.
