The Volcano Quartzite Silent Blade 350mm (Part Number: NSSQ353220) is a professional, industrial-grade diamond bridge saw blade engineered specifically for high-efficiency wet processing of exceptionally hard natural quartzite slabs (such as Taj Mahal).
Because quartzite contains ultra-dense, highly abrasive quartz crystals, it easily glazes or destroys standard diamond tooling. This 350mm (14 inch) blade addresses that specific failure point by fusing an extremely soft metal-matrix segment bond with silver-brazed construction, forcing the blade to constantly shed its metal layer and expose razor-sharp industrial diamond grits continuously.
Key Specifications & Performance Features
• Physical Dimensions: Built with a 350mm (14 inch) outer diameter (D), a 3.2mm cutting thickness (W), and an extra-deep 20mm segment height (H) ensuring an extended operational life under production conditions.
• Ultra-Soft Matrix Bond: Tailored to intentionally erode at a controlled, uniform speed against quartzite's extreme hardness, eliminating structural glazing and maintaining clean feed speeds.
• Split Segment Geometry: Formulated with aggressive split/slotted segments that instantly eject thick, abrasive stone slurry, minimising peripheral friction and ensuring a chip-free edge finish.
• Dampened Silent Core: Built using a laminated steel sandwich plate that dynamically dampens high-frequency resonance and screaming during high-RPM wet cutting routines, protecting operators' hearing.
