Best Blade for Cutting Aluminum

Aluminum is one of the common materials you will be cutting as a DIYer or a professional. Maybe you will cut wood and wood composite some more. Aluminum is a relatively soft metal you would need for many home and professional projects.

Cutting aluminum could be challenging for first-timers. A big concern is knowing what tool is appropriate to cut without ruining the material or damaging the blade. Besides, using the wrong tool is also stressful and could predispose to workshop injuries. Cutting aluminum might give off some sparks and generate heat which might scare you.

These concerns are why we curated this review to help you determine the best blade for cutting aluminum. Check out our picks for different types of saws – circular, miter saws, hacksaws, reciprocating saws, and jigsaws.

What Type of Blade is Ideal for Cutting Aluminum?

You can use various types of saws to cut aluminum, depending on the use. For example, a good reciprocating saw blade is ideal for aluminum that is tough to reach. But it is not a good idea to cut bulks of aluminum tubes with it. We will consider various blade types in this review depending on the type of saw. 

There things to consider while choosing a circular saw blade. One is the number of teeth, as it determines your result. Blades with more teeth will give you a better cut than a blade with fewer ones. But blades with fewer teeth are ideal for cutting thick aluminum.The blades with triple chip grind teeth are best for aluminum because they reduce chipping.

For durability, the blade teeth should be carbide-tipped. The blade diameter determines how deeply your blade cutsand how fast it cuts. If you want to make deep cuts, you should consider getting a big blade above 7½ inches. It is usually better to use blades with thin kerfs for precision and cutting speed.

You need a reciprocating blade to cut aluminum in places you would not be able to reach with other types of saws. The higher the blade’s TPI (teeth-per-inch), the better it is. It should also be bi-metal and have carbide tips. For thin aluminum sheets or pipes, consider using a blade of 18 – 24 TPI to achieve a very smooth cut. A blade with 8 or 10 TPI is also great for aluminum.

Hacksaw blades with high TPI have shorter teeth and can cut thinner aluminum better. Blades with low TPI cut faster and better for thick aluminum when smoothness is not a priority.If you want to cut curves or shapes on aluminum, consider a jigsaw bladethat has a T-shank. This improves grip and gives the blade some stability. The blade should have a minimum of 24 fortified teeth.

Review of the Best Blades for Cutting Aluminum

Suppose you are considering getting the best blade for cutting aluminum. In that case, you need one that can give a smooth cut, last long, and guarantee some safety. The blade should also suit your saw and the type of cut. Here are some of the best blades you can get for circular saws, miter saws, hack saws, jigsaws, and reciprocating saws (Sawzall). 

  1.  The 7¼-Inch 68-tooth Irwin (4935560) Metal Cutting Circular Saw Blade

The 7¼-inch Irwin blade is one of the best circular saw blades for cutting aluminum and other high-gauge metals. It has a small diameter, so it is best used for shallow cuts. The blade features anti-vibration vents that minimize noise and vibration to keep the blade steady during cuts. This should give you more accurate cuts.

We recommend this blade for cutting thin aluminum. And because it gives a neat finish, it is especially good for trimming aluminum sheets and pipes to fit your measurement. In the splendor of its range, the blade can also cut thicker metals like ribbed steel. Its 68-tooth carbide tip makes the blade last longer and cuts smoother.

The blade is big on safety as it is designed to prevent kickbacks and reduce the sparks during cuts, which could predispose to workshop injuries. It also has a lower dust production when you compare it with other blades.

Key Features

A prominent feature of this 10-inch Freud blade is its ultra-thin kerf line. This helps you reduce waste, enjoy better accuracy and a faster feed rate. It is wider than the Irwin, which means it can cut a little deeper. It is a heavy-duty blade with impressive HI-density carbide tips on its 80 teeth. These prolong the life of the blade and reduces the frequency of sharpening.

There are four gullets to demarcate these teeth to remove the aluminum chips. It has a -5 degrees teeth hook and a triple chip grind (TCG). Asides from cutting aluminum, it is also an excellent blade for brass and copper. The manufacturers recommend you use a lubricant after 4 or 5 cuts. The blade withstands rust and corrosion with a silver ice coat. 

This blade fetches you a good value for your money. Many reviews attributethis to the longevity of the blade and its accuracy while cutting. People have used the blade on extruded aluminum and got desirable results.

The triple chip tooth arrangement gives burr-free cuts with clean results for aluminum and other non-ferrous materials like copper, brass, and bronze.

It gives you a conducive work environment with noise reduction thanks to its copper-plugged expansion slots. The slots also reduce the vibration and contribute to the precise and smooth results seen with the blade. Generally, you may have to use a lubricant while cutting any non-ferrous metal. 

The blade is of reinforced steel to prevents it from bending or deflecting while cutting. This helps to deliver straight cuts.It is designed to cut heavy metals like extruded aluminum. Make sure you clamp the aluminum. Else, you might break one or more teeth. The blade will still cut like it is not missing anything, though.

Key Features

The large green exquisite blade is suitable for cutting aluminum. Its favorite feature should be its dry-cut technology. Using the blade only generates little heat with few burrs so much that you can handle the aluminum almost immediately after cutting.

The 14-inch wide 80-tooth circular blade is carbide-tipped to extend its life. As it is not an abrasive blade, it lasts a lot longer.

  1. What is the best tool for cutting aluminum?

The best tool for cutting aluminum largely depends on the type of cuts you want to make. Power tools are more reasonable for a professional. While a DIYer could be okay with a hacksaw or Sawzall, depending on the type of cut. Jigsaws are ideal for cutting in curves or shapes. Big industries might use laser for their cutting.

  • Is cutting aluminum dangerous?

Yes, it can be dangerous if you do not use the right tools or take precautions. Cutting aluminum might give off some sparks and generate some heat from the friction, significantly if you are cutting with a power tool. In that case, you should wear protective gear – goggles, thick rubber gloves, an apron, and suitable footwear. 

  • Can a carbide blade cut aluminum?

Yes, it can. A carbide blade is ideal for cutting aluminum because it gives smoother cuts and prolongs the life of the blade.

  • Can I use a hacksaw to cut aluminum?

Yes, you can. In fact, hacksaws are originally designed to cut metals like aluminum and alloys. A handheld hacksaw with 32 teeth should cut your aluminum without stress – unless the aluminum is very thick. That might take some time, and it would be better to use a power tool. 

  • How do you cut thick aluminum?

Use an excellent carbide-tipped blade mounted on a circular saw. If you are making a miter or bevel cut, you should mount the blade with a miter saw. The fewer the number of teeth the blade is, the easier it will cut the thick aluminum. Handheld saws would need a lot of physical exertion and consume time. You might require a lubricant to cool the blade intermittently.
