  • Angle grinder or tin snips
  • Safety gear

10 Ways How to Cut Metal Lath

1. Secure

Secure the metal lath on a flat surface. If you’re cutting a larger piece, use clamps to hold it in place. Also, make sure to wear safety goggles or glasses while cutting. Securing the lath will help to ensure a clean cut without any mistakes.

2. Measure

Measure out your cuts and mark them clearly with chalk or marker before starting. Make sure to double-check your measurements so that you don’t end up with an inaccurate cut. Measuring correctly is one of the most important steps in cutting metal laths.

3. Choose Your Tool

Choose the correct tool for the job. If you’re cutting a straight line, use an angle grinder or tin snips. For curved cuts and more intricate designs, use a hacksaw. Electric shears can also be used for cutting metal laths, but they are only effective on longer pieces that require straight cuts.

4. Make the Cut

Once you’ve chosen the right tool for the job, make sure to use a steady hand and go slow when making your cuts. You don’t want to rush through them and end up with an uneven or sloppy cut.

5. File Down Rough Edges

Once you’ve made your cuts, take a file and smooth out any rough edges left behind. This will to ensure that the finished product is uniform and aesthetically pleasing.

6. Wear Safety Gear

Always wear appropriate safety gear when cutting metal laths, such as goggles and gloves. This will help to prevent any injuries from sharp edges or flying debris. Wear a face shield if you’re using an angle grinder.

7. Pay Attention to Heat

Pay attention to the amount of heat generated when cutting metal lath, as this can cause it to warp or bend. If the lath is getting too hot, take a break and allow it to cool down before continuing with the project.

8. Pre-Bend the Metal Lath

If you’re cutting a curved line, pre-bend the metal lath before making your cut. This will make it easier to bend into the desired shape and reduce the chances of warping or bending. Metal lath can be pre-bent with a pair of pliers.

9. Use an Oil or Lubricant

When using a hacksaw to cut metal lath, use an oil or lubricant such as WD-40 to make the saw’s job easier and reduce friction buildup. This will help to ensure that you get a clean, smooth cut every time.

10. Have Fun!

Last but not least, have fun with the project! Cutting metal lath is an enjoyable and rewarding experience that can help you hone your handyman skills. With a bit of practice and patience, you’ll be able to create beautiful crafts and projects out of metal lath in no time.

8 Safety Precautions to Follow

When cutting metal laths, safety is paramount. It’s important to follow these eight steps:

1. Wear appropriate protective gear. Before beginning the job, make sure you have the right type of eye protection and gloves to protect your hands. It is important to also wear a dust mask to prevent inhalation of any particles created during the cutting process.

2. Double-check that your power tool is in good condition and properly maintained. Be sure to inspect your saw blades for any damage before beginning the job, as well as ensure that all the parts are securely fastened together.

3. Make sure to use the proper saw blade for cutting metal laths. There are types of blades that are specifically designed for cutting through this material and using other blades could lead to poor results and damage the lath in the process.

4. Place the lath on a level surface before beginning to cut it. This will give you more control over the saw and help to ensure that you get a clean cut. Cleaning the area of dust and debris before cutting can also help to make sure that the surface is level.

5. Secure the lath in place with clamps or a vice grip if necessary. This will hold it firmly in place while you cut, helping to ensure a clean cut without any wobbling or slipping. Securing the lath will also help you to keep your hands away from the blade while cutting.

6. Keep a steady but slow speed when cutting through metal lath. Going too fast can cause the saw to bind and kick back, which can be dangerous. Speed is also important if you’re using a powered saw; going too slow can cause overheating and damage the saw blade.

7. Allow for adequate cooling time between cuts, especially when using an electric or battery-powered saw. Letting the blade cool down helps to prevent it from becoming damaged by heat. Allowing the blade to cool off also helps it to last longer.

8. Dispose of any metal shavings or debris created during the cutting process properly. Metal shavings can be sharp and dangerous, so make sure to clean them up carefully and dispose of them in accordance with local regulations.

By following these eight safety precautions, you can ensure a safe and successful job when cutting metal laths.
