Direct Answer: Silent core diamond blades feature a composite steel core engineered with a thin noise-damping copper or acoustic foil laminated between two outer steel plates. This sandwich structure absorbs high-frequency sawing vibrations, reducing blade resonance noise by 10 to 15 decibels (a 50% perceived reduction in sound volume). They are essential for indoor hospital renovations, occupied office buildings, and urban night sawing.
Standard solid steel core blades act like tuning forks during sawing, producing high-decibel screeching noise that violates municipal noise ordinances and indoor decibel limits.
