Carbide blades provide unmatched durability and precision in asphalt cutting, with tungsten carbide inserts lasting 5-10 times longer than standard steel. SENTHAI manufactures OEM-grade blades optimized for graders, saws, and pavers, ensuring minimal downtime, superior wear resistance, and consistent performance across high-abrasion road projects.
What Are Carbide Blades for Asphalt Cutting?
Carbide blades consist of tungsten carbide tips or inserts brazed onto steel bases, designed specifically to resist abrasion from silica-rich asphalt. SENTHAI produces these using automated sintering, welding, and vulcanization for strong, long-lasting bonds. These blades are ideal for walk-behind saws, handheld cutters, and grader edges, preventing segment loss and maintaining sharpness over extended use.
Key advantages include reduced replacement frequency, lower operational costs, and consistent cutting precision. SENTHAI’s JOMA-style and I.C.E. blades integrate seamlessly into existing road construction equipment, delivering reliable performance in demanding environments.
| Blade Type | Material | Best Use | Wear Life Multiplier |
|---|---|---|---|
| Carbide Insert | Tungsten Carbide + Steel | Asphalt Grading | 5-10x Steel |
| Carbide Tipped | WC Overlay | Saw Cutting | 3-7x Steel |
| Serrated Carbide | WC + Heat-Treated Steel | Abrasive Roads | 4-8x Steel |
How Do Carbide Blades Work in Road Construction?
Carbide blades cut asphalt using the extreme hardness of tungsten carbide, shearing material while the steel base absorbs shock. Inserts may rotate or self-sharpen, preventing uneven wear on graders. SENTHAI’s wet grinding process ensures uniform carbide distribution for consistent cutting.
During milling or scarifying, blades penetrate asphalt layers efficiently, loosening material for repaving. Vibration reduction and precise welding help prevent fatigue cracks. For high-HP saw applications, these blades provide clean, precise grooves with minimal chipping. Regular insert rotation extends service life.
What Makes Carbide Blades Superior for Asphalt?
Carbide outperforms steel by resisting abrasion 5-10 times longer, maintaining sharpness under heat and friction. SENTHAI ensures consistent carbide density through automated production. Their blades tolerate impact without breaking, while overlay designs distribute wear evenly to maintain road surface quality. Longer lifespan reduces environmental waste, and ISO14001 certification confirms SENTHAI’s commitment to sustainable production.
Which Carbide Blade Type Is Best for Your Project?
For graders on abrasive asphalt, curved double-bevel blades excel. Flat serrated blades are optimal for utility saw cuts. SENTHAI provides a range of widths from 6-16 inches, with OEM customization options to match equipment specifications. Blade choice should consider machine horsepower, cutting depth, and material abrasiveness.
| Application | Recommended Blade | SENTHAI Model | Arbor Size |
|---|---|---|---|
| Road Grading | Curved Carbide | JOMA Style | 5/8″ |
| Asphalt Sawing | Drop Segment | Carbide Insert | 1″ |
| Milling | Serrated Tipped | I.C.E. Blade | 20mm |
