Since your chainsaw just won’t “cut it” for your aluminum projects, it’s time for you to buy a great circular saw and an appropriate cutting blade.
It is important to keep in mind that not all blades are created equally. A certain saw blade may be the best for your friend, but it may fail to serve you. Similarly, not all blades are meant for the kinds of cut you are looking for.
Using blades with inappropriate thickness and teeth can cause injury to you or others and may damage the surface you’re cutting. It all boils down to your requirements, and this is why this section becomes more important. Here are some things to consider.
Types Of Circular Saw Blades For Cutting Aluminum
There are two main types:
- Metal Cutting Blade – This type of blade has smaller teeth separated by sturdy slots. This design helps in cutting metal pipes and sheets. You can’t cut through thick blocks of metal with this one, however; it is ideal for thinner sheets up to 11 gauge.
- Abrasive Blades – These blades are carved out of fiberglass for extra strength and durability. They are ideal for cutting through slightly thicker plates, bars, and tubes of metal.
Kerf is the thickness of the blade. As it goes through immense wear and tear, the kerf is one of the most important consideration while buying a new blade. Thicker blades can be made sharper and tend to cut faster as well. Thinner kerfs are more suitable for saws with smaller motors. However, they are less durable than thicker blades.
The sharp, tiny guys around the edge of the blade are the teeth. The number of teeth will decide the nature of the cut; more teeth mean a cleaner cut while fewer teeth result in a rougher cut. Some blades have 24 teeth, while others can have as many as 100.
It is a small area between two teeth and is used for chip removal. Deeper gullets are used for bigger pieces of chips while shallower gullets are ideal if the material you’re cutting produces fewer, smaller chips.
Hook angle, also known as “rake”, is the angle of the teeth with respect to the center of the blade. Negative hook angle is created when the top of the teeth is positioned away from the blade movement. During the cutting process, this design can slow down the feed rate.
Positive hook angle, on the other hand, is when the top of the teeth are in the direction of the blade movement. It results in more aggressive cuts.
Can I Use Circular Saw Blades On A Table Saw?
Yes, you may! Since the kerf is thinner, it requires less power.
Which Direction Should I Cut?
Circular saw blades are designed to cut upwards, starting from the bottom of your aluminum sheet (or wood) to the top. Also, almost all manufacturers have an arrow pointing in the right direction on guard blade.
Is It Possible To Sharpen The Blade?
Yes. And you can do it yourself using an oil stone and a file. There are also many blade sharpeners available in the market.

Most people say this circular saw blade has really good performance, but the only problem is that it does not fit in the standard size saws. So you have to be particular in choosing the right one to fit.
- Multi-purpose blades

After rating all the products, the Oshlun 60 Tooth Saw Blade (Diamond Knockout) is a standout performer among the rest with a rating of 4.8. Especially if you compare what you get to price tag attached to it.
The only product competing with the Oshlun 60 is the Diablo D1080N Saw Blade, but its one flaw is its high price. However, if you want the very best blade for cutting aluminum, go for it, so long as you are ready to pay for that pure quality.
