TOMAX 12-Inch 100 Tooth TCG Blade
The TOMAX 12-Inch 100 Tooth TCG blade is designed for cutting aluminum and non-ferrous metals with high-tooth geometry that promotes smooth, burr-free cuts. Construction-grade carbide teeth provide longer life, while an electrophoretic coating resists rust and corrosion. The 1-inch arbor matches most standard miter saws, and the blade’s fine tooth count prioritizes clean edges on thin materials, making it a versatile choice for metal fabrication and aluminum framing projects.
Diablo Steel Demon Cermet II Saw Blade
The Diablo Steel Demon Cermet II blade delivers up to 25x longer life and cooler cuts via advanced Cermet II teeth, designed for metalworking where heat build-up is a concern. The 80-tooth configuration and 1″ arbor enable precise, fast cutting with reduced burrs on thin metals. Laser-cut stabilizer vents and Tri-Metal shock-resistant brazing minimize vibration and deflection, helping you achieve straight, accurate cuts even on challenging materials.
FOXBC 12 Inch Aluminum Cutting Blade – 120T
The FOXBC 12-Inch Aluminum Cutting Blade features 120 teeth and a 1-inch arbor, optimized for cutting thin to medium aluminum sections and related non-ferrous materials. The high-density carbide teeth promote long cutting life and clog-free performance, while the fine kerf and negative hook angle help deliver smooth finishes with reduced chipping. Its design aims to balance speed with precise edge quality on aluminum extrusions and similar metals.
Diablo Saw Blade for Medium Aluminum – 12″ 96 TCG
Designed for clean aluminum cuts, this Diablo blade uses 96 TCG teeth paired with Tri-Metal Shock-Resistant Brazing to endure impact and resist heat, producing burr-free finishes. The Perma-SHIELD non-stick coating reduces gumming and coating buildup, helping maintain peak performance and extending blade life in repetitive aluminum cutting tasks.
TOMAX 12 Inch 60 Tooth Industrial Blade
The TOMAX 12-Inch 60-Tooth Industrial Blade is designed for ferrous metal cutting, offering a heat-tolerant Cermet tooth set that provides longer life than traditional abrasive discs. It’s tuned for steel profiles, pipes, and channels, delivering reliable performance for fabrication or light fabrication shop workflows that require steady, cooler cutting in mild steel and related ferrous materials.
Buying Guide
- Material compatibility: Determine whether you primarily cut aluminum, non-ferrous metals, or ferrous metals to pick the correct tooth geometry and kerf. Higher tooth counts (80–120) typically yield smoother finishes on softer metals, while lower counts (60) favor faster cuts in ferrous steel.
- Arbor and compatibility: Most 12-inch blades use a 1-inch arbor. Verify your miter saw’s arbor size and compatibility with the blade’s mount hardware to ensure safe, proper installation.
- Tooth design: Triple Chip Grind (TCG) is common for metal cutting, delivering smooth edges and reduced burrs on aluminum and non-ferrous metals. Cermet blades offer heat resistance and longer life in demanding environments; consider them if you cut hot or repeatedly.
- Coatings and finishes: Non-stick coatings (e.g., Perma-SHIELD) reduce gum-up and heat buildup, helping extend blade life and maintain performance. Coatings are especially beneficial when cutting brass, copper, or heavily lubricated metals.
- Cool cutting and burr control: Look for blades with stabilizers or venting to minimize vibration and deflection, improving accuracy on long cuts and reducing blade warp.
- Application notes: Some blades are optimized for thin extrusions, others for thicker profiles. Match the blade’s intended range (thin, medium, thick) to your typical material thicknesses to maximize performance and lifespan.
- Safety and maintenance: Always use the appropriate guard and push-stops. Regularly inspect teeth for chipping or wear and replace blades when performance declines to preserve work quality and tool safety.
