The following selections offer a balance of high tooth counts for clean finishes and robust carbides for durable performance in metal cutting environments.
COMOWARE 12″ Circular Saw Blade
This 12-inch, 100T TCG metal cutting blade is designed specifically for aluminum and non-ferrous metals. Its tungsten carbide teeth resist heat and wear, enabling extended durability during repetitive cuts. The 15-degree hook angle and trapezoidal teeth initiate scoring for clean starts, then clear material efficiently to minimize tear-out. The universal 1″ arbor fits a wide range of circular saws, ensuring stable operation and consistent results.
Key features include:
- Tungsten carbide teeth for wear resistance and heat tolerance
- TCG design with clean-cut initiation and effective material clearance
- 1″ arbor for versatile compatibility
Excel Blades 6-Inch Metal Mitre Box Set
The Excel Blades mitre box set is a compact option for precise 45° and 90° cuts, suitable for aluminum and plastic work. While primarily targeted at hobbyists and crafts, its hardened carbon steel blade and aluminum mitre box contribute to steady, accurate cuts in small runs or model-building tasks. The 46 TPI razor pull saw blade provides clean line work for softer materials and soft metals, supporting meticulous projects where precision matters.
Highlights include:
- Sturdy K5 handle for reliable control
- Predetermined angle slots for accuracy
- Aluminum mitre box and hardened blade for stability
TOMAX 7-1/4-Inch 60T Blade
This 7-1/4 inch blade is designed for cutting aluminum and non-ferrous metals with a 60T configuration. The construction-grade carbide teeth offer durability for longer blade life, and an electrophoretic coating helps reduce rust and corrosion, extending the blade’s service life in workshop conditions where exposure to moisture or humidity is possible.
Notable aspects:
- Coated surface to resist rust and corrosion
- Carbide teeth for life and performance in metal work
- Ideal for small-to-medium aluminum tasks and plastics
TOMAX 10-Inch 80 Tooth Blade
This 10-inch blade uses an 80-tooth TCG configuration designed for aluminum and non-ferrous metals. Tomax emphasizes durability via construction-grade carbide teeth and an electrophoretic coating to combat rust. The 5/8″ arbor matches many standard chop and miter saws, making it a versatile option for aluminum extrusion work where a finer cut is desired.
Key takeaways:
- TCG grind for smooth, precise cuts
- High-tooth count for clean finishes
- Electrophoretic coating for corrosion resistance
FOXBC 12 Inch Aluminum Cutting Blade
This 12-inch blade is built specifically for aluminum with a 120T tooth count and a 1″ arbor. The high-density carbide delivers long blade life, and the included 120-teeth configuration supports thin, burr-free cuts through aluminum extrusions while providing stable performance and reduced clogging. The TCG grind enhances cut quality across varying thicknesses of aluminum.
Important points:
- 120T TCG configuration for fine, burr-free cuts
- 1″ arbor compatibility with common saws
- Durable carbide for extended life in metal cutting
FOXBC 10-Inch 80-Tooth Blade
This 10-inch blade with 80 teeth is designed for aluminum, non-ferrous metals, and plastics. It features a 5/8″ arbor and tungsten carbide teeth to provide wear resistance, reduce tool load, and help maintain sharpness over time. Laser-cut stabilizer vents reduce noise and vibration for better accuracy during cutting tasks.
Key characteristics:
- 80-Tooth TCG for smooth cuts
- 5/8″ arbor compatibility with many saws
- Laser-cut stabilizer vents to minimize vibration
Buying Guide: Key Purchase Considerations
When selecting a blade for aluminum extrusion cutting, consider the following factors to ensure optimal performance and tool life:
- Tooth count and grind type: Higher tooth counts (80–120T) and Triple Chip Grind (TCG) offer smoother finishes and cleaner cuts in aluminum. For thicker extrusions, a lower T count with robust carbide can be more economical and durable.
- Material and coating: Tungsten carbide teeth deliver long life in metal cutting. An electrophoretic coating helps resist rust in humid environments.
- Arbor size and compatibility: Confirm your saw’s arbor size (1″ vs 5/8″) and ensure the blade fits securely to reduce runout and vibration.
- Blade diameter: Larger diameters cut deeper; ensure your saw is rated for the blade size and that the kerf suits the material thickness without excessive waste.
- Heat management: Aluminum cuts generate heat; blades with sharper teeth and efficient chip clearance reduce heat buildup and maintain cutting accuracy.
- Application fit: For hobby projects or intricate work, a smaller blade with precise angles (mitre box sets) may be ideal. For continuous extrusion work, a high-durability metal-cutting blade is preferred.
Comparing the five blades above shows a spectrum from compact, craft-focused options to high-durability, industrial-grade blades. For frequent aluminum extrusion work, blades with 100–120 teeth and robust carbide tips (like the 12″ FOXBC and MAZING blades) tend to deliver cleaner cuts and longer life. For smaller projects or hobbyist tasks, the TOMAX options provide adequate performance with good rust resistance and compatibility with common saws.
