The Diablo 12" x 120-Tooth Aluminum Saw Blade for Thin Non-Ferrous Metal is a next-generation circular saw blade engineered for precision cutting of aluminum, copper, brass, plastic, and fiberglass. Designed for use on miter saws and slide miter saws, this 12" blade pairs an aggressive 120-tooth count with a -5 deg. hook angle and Diablo's specially formulated TiCo Super-Density Micro-Grain Carbide to deliver clean, burr-free cuts through thin non-ferrous metals - reducing rework and keeping job sites moving efficiently. Whether you're cutting aluminum extrusions, copper pipe, or brass plate, this blade is built for corded and cordless saw compatibility alike.

Key Features

• TiCo Super-Density Micro-Grain Carbide - withstands impact, reduces wear, and provides clog-free cuts that last longer than standard carbide in metal cutting applications, meaning fewer blade changes over time.
• Triple Chip Grind (TCG) Tooth Geometry - delivers clean, burr-free finishes on aluminum and non-ferrous metals, virtually eliminating rework and saving time on the job.
• Tri-Metal Shock Resistant Brazing - bonds carbide teeth to the steel plate with extreme impact resistance for maximum durability when cutting hard non-ferrous materials.
• Laser-Cut Stabilizer Vents - trap noise and reduce vibration during cutting, improving cut accuracy and extending the working life of the blade.
• Perma-SHIELD Non-Stick Coating - protects the blade body against heat, gumming, and corrosion, keeping the blade running smoothly through aluminum and other materials that tend to load up standard blades.
• 120-Tooth Count at 12" Diameter - provides a high tooth density suited to thin non-ferrous stock (up to 1/8"), producing smooth surface finishes without burring or tearing.
• -5 deg. Hook Angle - a negative hook controls the cut aggressiveness for safer, more controlled feeding through metal stock, reducing the risk of blade grab.
• .091" Kerf /.071" Plate - a thin plate with a controlled kerf reduces material waste and keeps cutting effort low, particularly on thinner aluminum stock.

Why This Product

• Built specifically for thin non-ferrous metal cutting (aluminum up to 1/8"), this blade's 120-tooth carbide configuration produces finished-quality cuts that eliminate the need for secondary deburring or sanding after each pass.
• The TiCo Super-Density Micro-Grain Carbide formulation is designed to outlast standard carbide in metal cutting applications - making this blade a cost-effective choice for shops and contractors who regularly cut aluminum extrusions, copper pipe, or brass plate.
• With a 1" arbor and a maximum rating of 5000 RPM, this blade is compatible with both corded and cordless 12" miter saws and slide miter saws, giving it broad versatility across jobsite setups and equipment brands.
• The combination of Laser-Cut Stabilizer Vents and Perma-SHIELD Non-Stick Coating reduces heat buildup and blade flex during extended cuts through aluminum and plastic - helping maintain cut-line accuracy on repeat production runs.

Frequently Asked Questions

What materials can this Diablo blade cut?

This blade is designed for cutting aluminum, copper, brass, plastics, and fiberglass. It is optimized for thin non-ferrous metal stock and is particularly well suited to cutting aluminum extrusions, copper pipe, and brass plate on the jobsite.

What saws is the D12120N compatible with?

The D12120N is designed for use with miter saws and slide miter saws. It features a 1" arbor and a maximum rating of 5000 RPM, and is suitable for both corded and cordless saw configurations.

What tooth geometry does this blade use, and why does it matter for metal cutting?

This blade uses a Triple Chip Grind (TCG) tooth design. TCG geometry is specifically suited to cutting non-ferrous metals and hard materials because it alternates between a flat-top tooth and a chamfered tooth, resulting in clean, burr-free finishes that virtually eliminate rework after each cut.

How does the TiCo Super-Density Micro-Grain Carbide differ from standard carbide?

Diablo's TiCo Super-Density Micro-Grain Carbide is a specially formulated carbide designed to withstand impact, reduce wear, and provide clog-free cuts in metal cutting applications. According to Diablo's product data, this formulation lasts longer than standard carbide when used for cutting aluminum and other non-ferrous metals.
