Aluminum is a versatile metal that is used in various industries, including construction, automotive, and aerospace. Its lightweight and corrosion-resistant properties make it an ideal material for many applications. However, cutting aluminum can be challenging, especially if you do not have the right tools. One of the most important tools for cutting aluminum is a circular saw, but not all circular saw blades are created equal. In this article, we will discuss what kind of circular saw blade to use when cutting aluminum.
First, it is important to understand the anatomy of a circular saw blade. A circular saw blade has several components, including the teeth, gullet, plate, and arbor hole. The teeth are the cutting edges of the blade, and they come in different shapes and sizes depending on the material being cut. The gullet is the space between the teeth, which helps to remove the chips or debris from the cut. The plate is the body of the blade, and it can be made of different materials, such as steel or carbide. The arbor hole is the center hole of the blade, which fits onto the arbor of the saw.
When cutting aluminum, it is important to choose a circular saw blade that is designed for this material. Aluminum is a soft metal, and it can easily gum up or clog the teeth of the blade. Therefore, it is recommended to use a blade with fewer teeth than a blade used for cutting harder materials like wood or steel. A blade with 60 to 80 teeth is ideal for cutting aluminum, as it will produce a cleaner and smoother cut.
Another important consideration when choosing a circular saw blade for cutting aluminum is the type of tooth configuration. There are three main tooth configurations: flat top grind (FTG), alternate top bevel (ATB), and triple chip grind (TCG). FTG blades have teeth that are square or flat on the top, and they are ideal for ripping or cutting with the grain. However, they are not recommended for cutting aluminum, as they can easily clog up. ATB blades have teeth that are angled on the top, which allows for a smoother cut. They are a good choice for cutting aluminum, but they can be more expensive than FTG blades. TCG blades have a combination of teeth with flat tops and teeth with angled tops, which makes them ideal for cutting hard materials like aluminum. They are also more expensive than ATB blades.
In addition to the tooth configuration, the material of the blade is also important when cutting aluminum. Carbide-tipped blades are a popular choice for cutting aluminum, as they are durable and can withstand the abrasive nature of the material. They are also more expensive than steel blades, but they will last longer and produce a cleaner cut. Steel blades are a more affordable option, but they are not as durable as carbide-tipped blades and may need to be replaced more frequently.
When using a circular saw to cut aluminum, it is important to follow safety precautions. Always wear safety goggles and ear protection, and make sure the blade is securely attached to the saw. Use a clamp or other device to secure the aluminum sheet to the work surface, and make sure the blade is at the appropriate height and angle for the cut. Use a steady and controlled motion to guide the saw through the aluminum, and avoid forcing the blade or making sudden movements.
In conclusion, when cutting aluminum with a circular saw, it is important to choose the right blade for the job. A blade with 60 to 80 teeth and an ATB or TCG tooth configuration is recommended, and carbide-tipped blades are a durable and effective choice. Follow safety precautions when using the saw, and practice a steady and controlled cutting motion for the best results. With the right blade and technique, cutting aluminum can be a smooth and efficient process.

Frequently Asked Questions (FAQs) – What Kind Of Circular Saw Blade To Cut Aluminum?
1. What type of circular saw blade is best for cutting aluminum?
There are two types of circular saw blades that are best for cutting aluminum – carbide-tipped blades and diamond blades. Carbide-tipped blades are more affordable and can cut through aluminum easily. Diamond blades, on the other hand, are more expensive but they offer clean cuts and last longer.
2. Can I use a regular circular saw blade to cut aluminum?
No, you shouldn’t use a regular circular saw blade to cut aluminum. Regular blades are designed for cutting wood and other soft materials. They are not strong enough to cut through aluminum and may cause the blade to overheat or become damaged.
3. What size blade do I need to cut aluminum?
The size of the blade you need to cut aluminum depends on the thickness of the material you are cutting. For materials up to 1/8 inch thick, a 7 1/4 inch blade is ideal. For thicker materials, a 10-inch blade may be necessary. It’s important to choose the right blade size to ensure a clean and efficient cut.
4. How do I maintain my circular saw blade for cutting aluminum?
To maintain your circular saw blade for cutting aluminum, you should clean it regularly with a wire brush or blade cleaner. Make sure to remove any debris or built-up material on the teeth of the blade. You should also store the blade in a dry and cool place to prevent rusting. Finally, make sure to follow the manufacturer’s instructions for sharpening or replacing the blade when necessary.
