Engineered for Abrasive Mastery
"In asphalt and green concrete cutting, the abrasive slurry acts like sandpaper on the steel core. At Supreme Diamond Tools, we’ve engineered the GP-DA-P series with Drop Segment Protection specifically to combat this 'undercutting' effect. This ensures you use every millimeter of the massive 12mm segment height, delivering the highest ROI for road crews and rental fleets."
— The Supreme Diamond Technical Team
The Supreme Premium Asphalt Series is a high-performance solution designed for the most abrasive environments. Whether you are cutting green concrete expansion joints or performing road patching, these laser-welded blades provide the heat resistance and structural integrity required for intensive dry cutting applications.
| Product Code | Diameter | Width | Segment Height |
|---|---|---|---|
| GP-DA12P | 12" (300mm) | .125" | 12mm (.475") |
| GP-DA14P | 14" (350mm) | .125" | 12mm (.475") |
| GP-DA16P | 16" (400mm) | .125" | 12mm (.475") |
| GP-DA18P | 18" (450mm) | .140" | 12mm (.475") |
| GP-DA20P | 20" (500mm) | .140" | 12mm (.475") |
Green concrete is exceptionally abrasive because the sand particles are still loose. If you are cutting expansion joints within 4 to 8 hours of pouring, the GP-DA-P Series is your best defense. The 12mm drop segments are critical here to prevent the high-velocity sand from eroding the segment-to-core bond.

I’ve been using the 18-inch blade on a high-speed handheld saw for asphalt patching and utility trench work, and it’s been a dependable performer in dry-cutting conditions. 5 star
The 18" Supreme dry asphalt blade has been our go-to for 3 months now, and it’s solved our biggest dry-cutting headaches. It’s tough, fast, and made dry asphalt cutting less of a hassle. this blade gets the job done right, every time. Five stars easy.
I was initially concerned about core erosion, but the drop segment protection seems to be doing its job perfectly. I highly recommend it to any contractor looking for a reliable and long-lasting dry-cutting solution.
Cuts asphalt and green concrete like a pro! The blade stays cool and durable even on long jobs—definitely worth the investment
Used it on asphalt for roadwork, and it performed flawlessly. Smooth cuts, minimal dust, and long-lasting. Highly recommend this asphalt cutting blade for high-speed saws.
