4" x 132" 400 Grit Flexible Diamond Sanding Belt – Efficient Polishing & Grinding for Hard Materials

Overview: The 4" x 132" 400 Grit Flexible Diamond Sanding Belt – Efficient Polishing & Grinding for Hard Materials is a professional-grade flexible diamond sanding belt engineered for heavy-duty material removal, precise wet grinding, and fine polishing on glass, stone, granite, marble, technical ceramics, and hard metals. Featuring electroplated diamond particles securely bonded to a tough, tear-resistant flexible backing, it delivers cool, aggressive cutting and consistent scratch patterns. Key Features Electroplated Diamond Matrix: Uniformly electroplated diamond crystals provide aggressive cutting speed and resist thermal loading. Flexible, Heavy-Duty Backing: Conforms smoothly to rubber contact wheels, slack-belt contouring, and flat platen grinding. Durable Precision Joint: Reinforced seamless splice joint ensures smooth, chatter-free rotation across grinder pulleys. Applications Glass cold working, bottle neck grinding, edge beveling, and art glass finishing Lapidary gemstone cabbing, mineral specimen pre-polishing, and granite edge profiling Ceramic tile contouring, porcelain smoothing, and thermal spray coating finishing Operating Guidelines Coolant: Always operate with continuous water lubrication to flush slurry, prevent thermal loading, and extend belt lifespan. Tension: Maintain proper belt tension without over-stretching the splice. Recommended Speed: 2,000 to 4,500 SFPM depending on machine configuration.
