OEM Asphalt Over Concrete Blade Manufacturers & Exporter

Standard blades are formulated for a single material. Asphalt-only blades use an extremely hard bond that glazes over and ceases cutting when it contacts cured concrete or steel rebar. Conversely, concrete blades feature a soft bond that erodes rapidly in abrasive asphalt, causing severe undercutting and segment detachment. OEM Asphalt Over Concrete (AOC) blades use hybrid bonds and undercut drop segments to handle both materials effectively.

Undercut protection segments extend deeper down the steel core than standard cutting segments. When cutting through highly abrasive asphalt topping, the slurry flows toward the blade core. These deeper segments displace the abrasive slurry, preventing it from washing away the weld zone and preserving structural stability throughout the blade's operating life.

Yes. We regularly formulate bonds for specific regional materials, from hard river gravel and quartzite to softer limestone and recycled asphalt pavement (RAP). By analyzing your jobsite parameters—including equipment horsepower and wet/dry requirements—our metallurgists tailor diamond grit size, concentration, and matrix hardness to your operational needs.

Every batch undergoes automated optical segment dimension verification, computerized dynamic balancing to eliminate high-RPM vibration, radial runout inspection, and destructive shear-torque testing in line with EN13236 protocols. Mill test certificates, balance reports, and CE/SGS documentation accompany all international orders.

Standard OEM production runs start at 50 to 100 units per diameter for custom packaging and laser branding. Standard turnaround times range between 20 to 30 calendar days from CAD drawing approval. Rapid sample production is available within 7 business days for qualification testing.
