How to Pick the Best Miter Saw Blades for Cutting Aluminum

Most miter saws are capable of cutting aluminum. Still, you will need to carefully consider the blade on the miter saw when making your cuts. As a rule of thumb, you want to select blades that have a high number of teeth or a high TPI. The more teeth there are, the smoother the cut will be.

Furthermore, you want to select the different blade types based on the cut you want to make. Here’s a look at the most popular miter saw blade types based on cut:

  • Circular blades: Best for tilting angles to cut into shapes
  • Sharp cut blades: Best for sharp cuts
  • Razor blades: Best for high-precision cuts
  • Coarse/very coarse cut blades: Best for fine finishing

So, select a blade based on TPI and your intended job. If you consider these two factors, you will be able to find a miter saw blade that properly and safely cuts the aluminum the way you want it to be cut.

What You’ll Need

  • Protective gear
  • Goggles
  • Ear protection
  • Gloves
  • Pants and long sleeves
  • Miter saw
  • Aluminum piece
  • Lubricant

Instructions

Begin by putting on your protective gear. Because you will be cutting aluminum, the last thing you want is for fine metal pieces to injure you. Wear eye goggles, gloves, ear protection, pants, and long sleeves to keep yourself protected.

Once you are thoroughly protected, mount the blades. Remember, select blades based on the intended job and the size of your aluminum. In order to mount the blades, remove the blade that is currently mounted by opening the blade guard. Insert the new blade in its place.

Next, clamp the aluminum metal down. This will ensure that the aluminum stays in place so that the blade only cuts where you want it to cut. It also ensures that you stay safe during the process. Ensure that the clamps are secure before getting started.

Now that the aluminum piece is clamped down, you can begin cutting it. Make sure to align the blades in such a way that they will cut the intended area. Hold one hand on the aluminum and lower the miter saw handle down so it begins cutting the material. As you are cutting, add lubrication to the aluminum piece so it cuts a little bit easier.

Go slow and steady until you have completely cut the aluminum piece to its desired size and shape.

Tips

Here are some tips to make the cutting process even easier:

  • Double check that you have the right set of blades.
  • Double check your clamp before getting started. This will save you a whole lot of time and wasted materials.
  • Use a wood backer to trap the aluminum while cutting.
  • Invest in a good lubricant to ensure the cutting process is as easy as possible.
