The Diablo D0654NA 6-1/2 in. x 54 Tooth Medium Aluminum Cutting Saw Blade is a carbide-tipped circular saw blade made for cutting aluminum and other non-ferrous materials with a standard 6-1/2 inch saw. This is a circular saw blade designed for medium aluminum cutting. Model D0654NA gives you a 54-tooth layout for cleaner, more controlled cuts than a rough framing blade can deliver.

What matters here is how the specs work together. The 6-1/2 inch diameter fits compact circular saws that tradespeople already use for trim, punch work, and light fabrication. The 54-tooth count is aimed at smoother cutting in aluminum, while the carbide tooth construction helps the blade hold up better when you are working through repeated cuts in non-ferrous stock.

The Diablo D0654NA is not just limited to aluminum. Source data lists it for cutting aluminum, copper, plastics, brass, and fiberglass, which makes it a practical choice when your work jumps between different materials and you do not want to keep swapping blades. For installers, fabricators, and remodelers, that kind of versatility saves time.

Fitment is straightforward. This blade uses a 5/8 inch arbor and includes a diamond knockout, with the blade marking also showing a 13/16 inch knockout size. That gives you broader compatibility with saws that accept those common arbor configurations. It is also marked for use with corded or cordless saws, which is useful if your setup changes between shop work and jobsite work.

On the performance side, the maximum speed is rated at 10,000 RPM. That is an important number because it tells you this blade is built to run safely within the speed range of many 6-1/2 inch circular saws, provided your saw and application match the blade specifications. The thin .083 inch kerf and approximately 0.06 inch plate thickness help keep cuts efficient without making the blade overly heavy for a smaller saw platform.

If you cut aluminum trim, channel, sheet, or similar non-ferrous materials and want a blade that is purpose-built for that work, this one makes sense. It is a better fit for controlled aluminum cutting than trying to get by with a general wood blade, and it is especially useful for pros and serious DIY users who need cleaner edges and more predictable results from a compact circular saw.

Diablo D0654NA is a smart pick for cleaner aluminum cuts

If you are trying to cut aluminum with a standard wood blade, this is the upgrade that actually makes sense.

• Who it's for: Contractors, installers, and serious DIY users cutting aluminum and other non-ferrous materials with a 6-1/2 inch circular saw.
• Why it stands out: The 54-tooth carbide layout, 10,000 RPM rating, and common 5/8 inch arbor make it a practical purpose-built blade instead of a compromise.
• Worth knowing: This is a specialized cutting blade for aluminum and similar materials, not a general framing blade for wood.

• What materials can this blade cut? Source data lists aluminum, copper, brass, plastics, and fiberglass.
• What arbor size does it use? The arbor size is 5/8 inch, and the blade includes a diamond knockout.
• What is the maximum blade speed? The maximum rated speed is 10,000 RPM.
• Is this a wood cutting blade? No. Source data identifies the wood cutting type as not applicable and the application as medium aluminum cutting.
