High Frequency Welded Diamond Blade with BigU-slot for Asphalt
Short Description:
This product series comprises high-frequency welded diamond blades with BigU-slot designed specifically for cutting asphalt. The range includes multiple models (JC125121230, JC125141232, JC125161236, JC125181238, JC125201240, JC125241245, JC125281250, JC125321255) with diameters spanning 12″ (314mm) to 32″ (814mm), all featuring a 12mm segment height and 25.4mm bore. Thickness varies by model (3mm–5.5mm), and other larger sizes can also be supplied.
a. Product Features and Advantages:
- High-Frequency Welding Process: Ensures strong economic applicability by securely bonding diamond segments to the steel core, balancing cost-effectiveness with reliable cutting performance.
- BigU-Slot Design: Features large U-shaped notches precisely cut around the entire circumference (extending from the cutting edge toward the center but not fully penetrating). This reduces friction and heat buildup during operation, enables efficient debris expulsion, improves cutting efficiency, and prevents blade warping.
- Robust Construction: Built from high-grade steel with a durable circular design, finished in metallic silver-grey for corrosion resistance and aesthetic consistency.
- Reinforced Cutting Edge: The cutting edge is reinforced with a darker, diamond-impregnated segment for enhanced hardness and wear resistance, ensuring sustained sharpness in demanding asphalt cutting.
- Central Mounting Hole: Equipped with a central hole for easy attachment to standard cutting equipment (e.g., asphalt saws), facilitating stable and precise operation.
- Varied Specifications: Offers diameters from 12″ to 32″ and thicknesses from 3mm to 5.5mm (model-dependent) to accommodate different cutting depths and precision needs in asphalt applications.
- Extended Service Life: The combination of BigU-slots (for heat/debris management) and reinforced edges minimizes wear, extending operational lifespan under harsh asphalt sawing conditions.
b. Product Applications:
Ideal for cutting asphalt materials, particularly in asphalt sawing applications where efficient cutting, reduced heat generation, and prolonged blade durability are critical. Suitable for road construction, pavement repair, and asphalt surface processing tasks.
