Aluminium extrusions require a slower cutting speed compared to other materials. Set your circular saw to a lower speed to prevent overheating and ensure a cleaner cut. Higher speeds can cause the aluminium to melt and stick to the blade, resulting in rough edges.
6. Wear safety gear
When cutting aluminium extrusions, always wear appropriate safety gear, including safety glasses, gloves, and ear protection. Aluminium shavings can be sharp and may cause injury if not properly protected against.
Remember, practice makes perfect! Don’t be discouraged if your first few cuts are not perfect. With time and experience, you will improve your cutting skills and achieve the desired results.
Choosing the right blade
When it comes to cutting aluminum extrusions with a circular saw, choosing the right blade is crucial for achieving clean and precise cuts. The blade you select should be designed specifically for cutting non-ferrous metals like aluminum.
Material: Look for a blade that is made from a high-quality carbide material, as this will ensure durability and long-lasting performance. Carbide blades are known for their ability to maintain sharpness even after prolonged use.
Number of Teeth: The number of teeth on the blade is also an important factor to consider. More teeth generally result in a smoother cut, while fewer teeth can be more efficient for faster cutting. For aluminum extrusions, a blade with around 80 to 100 teeth would be ideal.
Tooth Grind: The tooth grind refers to the shape of the blade’s teeth. For cutting aluminum, a blade with a triple-chip or modified triple-chip grind is recommended. This type of grind helps reduce heat buildup and prevents the aluminum from sticking to the blade.
Blade Thickness: The thickness of the blade should be sufficient to handle the rigors of cutting aluminum extrusions. Look for a blade with a thickness of at least 1.8mm to ensure proper stability and minimize vibrations.
Blade Diameter: The diameter of the blade should match the size of your circular saw. Most circular saws can accommodate blades ranging from 7.25 to 10 inches in diameter. Choose a size that is suitable for your specific saw.
Additional Features: Some blades come with special features such as anti-vibration slots or coatings that reduce friction. These features can help improve the overall cutting performance and prolong the blade’s lifespan.
Remember to always wear appropriate safety gear, such as safety glasses and gloves, when working with a circular saw. Following these guidelines and using the right blade will ensure clean and accurate cuts when cutting aluminum extrusions.
