3.Craft & Performance

This 4.5‑Inch Vacuum Brazed Diamond Multi‑Purpose Composite Saw Blade is manufactured with advanced vacuum brazing craft. Diamond abrasive grains are metallurgically bonded firmly to the steel substrate, preventing grit shedding during heavy‑load cutting. The 4.5‑Inch Vacuum Brazed Diamond Multi‑Purpose Composite Saw Blade is designed with serrated segmented cutting rim and multiple round cooling holes across the disc surface. These holes accelerate air circulation to dissipate cutting heat rapidly, effectively reduce blade deformation and thermal wear during continuous operation.

Compared with ordinary cutting wheels, the 4.5‑Inch Vacuum Brazed Diamond Multi‑Purpose Composite Saw Blade delivers sharper cuts with less burr. It avoids easy‑to‑break thin resin cutting wheels. The rigid steel base provides high stability, less vibration while cutting. The 4.5‑Inch Vacuum Brazed Diamond Multi‑Purpose Composite Saw Blade supports both dry and wet cutting. When cutting hard materials, wet‑cutting is strongly recommended to extend service life. Every 4.5‑Inch Vacuum Brazed Diamond Multi‑Purpose Composite Saw Blade goes through strict visual and dynamic balance inspection before shipment to ensure safe and reliable performance for end‑users.
