Engineered for Burr-Free Precision
"Cutting non-ferrous metals like aluminum requires specialized heat management. Standard wood blades will 'gall' or clog almost instantly. At Supreme Diamond Tools, we engineered the GC-A Series with a specific Triple-Chip Grind (TCG) geometry. This allows the blade to slice through aluminum and brass without melting the material, ensuring a cool, burr-free finish that is ready for assembly immediately after the cut."
— The Supreme Diamond Engineering Team
The Supreme GC-A Series is a professional-grade Tungsten Carbide Tipped (TCT) solution designed for the rigorous demands of metal fabrication and window/door installation. Whether you are cutting thin-walled aluminum extrusions or thick copper busbars, these blades deliver industrial-level precision and an exceptionally long service life.
| Diameter | Tooth Count | Arbor Size | Primary Application |
|---|---|---|---|
| 7-1/4" – 8-1/4" | 60T / 80T | DM-5/8" | Portable Circular Saws |
| 10" (255mm) | 100T | 5/8" | Miter / Table Saws |
| 12" – 14" | 100T | 5/8" – 1" – 20mm | Heavy Fabrication Saws |
Lubrication is Key: To prevent aluminum 'chips' from welding themselves to the carbide teeth (galling), we highly recommend using a wax stick or a mist cooling system during the cut. This dramatically extends the life of your 100T blade and ensures a mirror-like finish on the cut edge. For thin plastics, ensure your material is firmly clamped to prevent shattering.
Aluminum Extrusions | Brass Sheets | Copper Busbars | Bronze Tubing | PVC Pipe | Acrylic & Plexiglas Panels | Fiberglass Grating
Q: Why is Triple-Chip Grind (TCG) necessary for aluminum?
A: TCG features a higher 'trapezoidal' tooth that does the heavy work and a lower 'flat' tooth that cleans up. This sequence breaks the metal chips into smaller pieces, which are easier to eject, preventing the blade from clogging and overheating.
Q: Can I use this on my DeWalt or Bosch miter saw?
A: Yes. Our 10" and 12" blades are precision-bored for a perfect fit on all major professional saw brands, ensuring a vibration-free performance.
