FAQs
What is the best sawzall blade to cut aluminum?
The ideal sawzall blade for aluminum combines fine teeth, bi-metal or high-speed steel (HSS) construction, and flexible backing to prevent bending. Blades labeled specifically for non-ferrous metals like aluminum tend to have 14–18 teeth per inch (TPI), which provides a balance between cutting speed and smoothness. High-quality bi-metal blades resist heat buildup, reducing the risk of blade dulling and aluminum sticking to the teeth. For thicker aluminum sheets, a blade with slightly fewer teeth (10–12 TPI) can improve efficiency, but it may produce a rougher edge.
What is the best blade for cutting aluminium?
The best blade for cutting aluminium is typically a fine-toothed bi-metal blade designed for non-ferrous metals. These blades have teeth shaped to avoid clogging with soft metals and provide a straight, clean cut. Look for blades that indicate “metal cutting” or “aluminum” on their packaging, as these are engineered for the softer, flexible nature of aluminum compared to steel. Specialty carbide-tipped blades can also be used for repeated or heavy-duty aluminum cutting but are usually overkill for general DIY tasks.
Do you need a special blade to cut aluminum?
Yes, using a standard wood-cutting blade is not recommended. Aluminum is softer than steel but can gum up wood or universal blades, causing rough edges and slowing progress. A specialized metal or aluminum-specific blade prevents binding, maintains precision, and extends blade life. Even a multi-purpose blade may perform inconsistently, so selecting a blade labeled for non-ferrous metals ensures optimal results.
How many tooth blade for cutting aluminum?
For aluminum, 14–18 TPI is ideal for sheets and thin profiles, offering smooth cuts without tearing the metal. Thicker aluminum (over 1/4 inch) can use 10–12 TPI blades for faster cutting but may leave a rougher finish. Always choose blades designed for non-ferrous metals, as they have geometry that prevents aluminum from sticking to the teeth and reduces vibration.
Conclusion
Selecting the best sawzall blade for cutting aluminum makes all the difference in precision, efficiency, and overall project quality. Fine-toothed bi-metal blades labeled for aluminum offer clean cuts and longer lifespan, while proper tooth count ensures smooth edges. Avoid generic wood or universal blades to prevent binding and reduce wear on your sawzall. By choosing the right blade, you can tackle aluminum projects confidently, whether for DIY home tasks or professional metalworking applications.
