The Diablo 5-1/2" x 50-Tooth Aluminum Cutting Saw Blade is purpose-built for fast, accurate cuts through aluminum and other non-ferrous metals using cordless trim saws. Featuring a 20mm arbor with three included bushings for compatibility with 1/2", 5/8", and 10mm arbor saws, this blade delivers the versatility professionals need across multiple tool platforms. Diablo's proprietary TiCo Hi-Density Carbide construction and Triple Chip Grind tooth geometry produce clean, burr-free results in medium aluminum, copper, brass, plastic, and fiberglass - making it the right choice when rework is not an option and battery runtime matters.

Key Features

• TiCo Hi-Density Carbide teeth engineered specifically for aluminum cutting - delivers extreme cutting life and clog-free performance in non-ferrous metal applications
• Triple Chip Grind (TCG) tooth design with 50 teeth - produces clean, burr-free finishes in aluminum and non-ferrous materials, virtually eliminating rework
• Tri-Metal Shock Resistant Brazing bonds carbide tips to the blade body - withstands extreme impact forces encountered in metal cutting for maximum long-term durability
• Advanced laser-cut thin kerf body at.061" - minimizes material removal and reduces cutting power demand, extending cordless saw battery life per charge
• Laser-cut stabilizer vents trap noise and vibration - keep the blade running cooler and reduce blade warp for more accurate, consistent cuts
• Non-stick Perma-SHIELD coating on the blade body - resists gumming from aluminum buildup, rusting, and corrosion for longer service life
• Includes three arbor bushings (1/2", 5/8", and 10mm) in addition to the native 20mm arbor - compatible with DeWalt, Makita, Black and Decker, Ryobi, Porter Cable, and Craftsman cordless saws
• -5 deg. hook angle optimized for non-ferrous metal cutting - controls chip load and reduces grabbing for safer, smoother cuts through aluminum stock
• Maximum rated speed of 14,500 RPM - suited for high-speed cordless trim saw operation without compromising blade integrity
• Rated for medium aluminum from 3/32" to 1/4" thickness, plus copper, brass, plastic, and fiberglass - covers a wide range of non-ferrous and composite materials in one blade

Why This Product

• Multi-arbor compatibility out of the box - the 20mm native arbor plus three included bushings (1/2", 5/8", 10mm) mean one blade works across DeWalt, Makita, Ryobi, Porter Cable, Craftsman, and Black and Decker cordless trim saws without purchasing additional adapters.
• Designed to protect cordless battery runtime - the thin.061" kerf removes less material per pass, requiring less motor effort, which translates directly to more cuts per battery charge on cordless saws.
• Burr-free cuts reduce finishing labor - the 50-tooth TCG geometry leaves clean edges in aluminum (3/32" to 1/4"), copper, brass, and plastic, so parts are ready to use without secondary grinding or filing.
• Italy-sourced construction with premium Diablo carbide - TiCo Hi-Density Carbide with Tri-Metal Shock Resistant Brazing provides durability in demanding metal-cutting environments where standard wood blades would fail quickly.

Frequently Asked Questions

Which cordless saw brands is this blade compatible with?

This blade includes four arbor sizes via the native 20mm arbor and three additional bushings: 1/2", 5/8", and 10mm. That covers DeWalt (20mm arbor), Makita (5/8" arbor), Black and Decker (1/2" arbor), Ryobi (10mm arbor), Porter Cable (10mm arbor), and Craftsman (10mm arbor) cordless trim saws.

What materials can this blade cut?

This 50-tooth TCG blade is designed to cut medium aluminum from 3/32" to 1/4" thick, as well as copper, brass, plastic, and fiberglass. It is not intended for ferrous metals such as steel or iron.

Why does this blade use a Triple Chip Grind (TCG) tooth design instead of a standard ATB grind?

The Triple Chip Grind tooth geometry is specifically engineered for non-ferrous metals and hard materials. It alternates between a flat-topped raker tooth and a chamfered tooth to shear material cleanly and reduce burr formation, which is critical when cutting aluminum, brass, copper, and similar materials where a standard Alternate Top Bevel grind would chip or load up.

What is the maximum cutting speed for this blade?

This blade is rated to a maximum of 14,500 RPM. Always confirm your saw's operating speed does not exceed this rating before use to ensure safe operation.
