Asphalt Saw Blade
Product Description
Laser Welded Heavy-Duty Road Cutting Diamond Blade - Asphalt & Concrete
Industrial Grade Laser Welding for Maximum Safety and Longevity
Engineered for professional road contractors and demolition crews working on highways, airport runways, and heavy infrastructure. This large-diameter diamond blade features advanced laser welding technology that creates a metallurgical bond between the steel core and diamond segments, eliminating the risk of segment loss during deep cutting. The optimized 15mm segment height provides extended life for continuous wet cutting of reinforced concrete and abrasive asphalt.
Key Features
- Laser Welded Segments: Metallurgical bond strength exceeds 800MPa - segment retention guaranteed even under overload conditions
- Deep Cutting Design: 15mm segment height allows cutting depths up to 350mm depending on saw configuration
- Drop-Segment Protection: Laser welding prevents dangerous segment ejection that occurs with sintered blades under heat stress
- Hybrid Bond Matrix: Cobalt-copper bond optimized for both abrasive asphalt and hard concrete with rebar
- Silent Core Option: Laser-cut noise-reduction slots with copper inserts reduce operating noise by 50%
- Reinforced Center: 60mm or 80mm arbor with heavy-duty steel plate (3.5mm thickness) resists warping under load

Primary Applications
- Highway Repair: Cutting expansion joints, removing damaged pavement sections
- Airport Runways: Precision cutting of asphalt and concrete without spalling edges
- Bridge Decks: Demolition cutting with rebar penetration capability
- Utility Trenches: Road cutting for water, gas, and electrical line installation
- Industrial Floors: Warehouse concrete slab modification and expansion joint cutting
⚠️ Safety & Operational Requirements
Segment Retention: Laser welding provides superior safety, but inspect welds before each use. Never use if cracks appear in core or segments.
Deep Cutting: When cutting >200mm depth, reduce feed speed by 30% to prevent core overheating and warping.
Pin Drive Requirement: Blades 400mm+ must use pin drive flanges to prevent arbor hole elongation under torque.
Wet Cutting Only: Dry cutting voids warranty and creates silica dust hazards. Minimum water flow 8 liters/minute.
