200mmx65mm 60Grit Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 200mm x 65mm (628mm length) 60 Grit Flexible Diamond Sanding Belt is tailored for standard 200mm (8-inch) expanding rubber drums, heavy lapidary cabbing units, and glass arrising machines. Featuring an aggressive electroplated 60-grit industrial diamond coating on a flexible, waterproof backing, this belt delivers rapid stock removal, fast pre-forming, and heavy edge beveling on hard brittle minerals, dense glass, and ceramics.

Key Features

• Rapid 60 Grit Stock Removal: Aggressive diamond grain cuts freely to shape cabochons, level slab edges, and arriss thick glass quickly.
• Engineered for 200mm (8") Expanding Drums: 628mm developed length grips securely under centrifugal drum expansion for slip-free operation.
• Heavy-Duty Waterproof Backing: Retains dimensional stability, flexibility, and tracking under continuous water flush and high mechanical tension.
• Smooth Butt-Joint Seam: Minimizes joint impact, eliminating surface chatter marks during continuous high-speed passes.

Applications

• Lapidary gemstone rough cabbing, agate/jasper pre-forming, and specimen leveling
• Architectural flat glass arrising, thick glass edge leveling, and bevel shaping
• Granite, quartz, marble, and porcelain tile edge shaping and rapid calibration
• Hard alloy deburring, thermal spray coating finishing, and weld seam leveling

Operating Guidelines

• Coolant: Always operate with continuous water flood or coolant spray to prevent diamond heat buildup and maintain fast cutting speed.
• Tension & Tracking: Mount securely onto 200mm expanding drums before reaching full operational RPM.
• Speed: Recommended surface speed 3,000 to 5,500 SFPM.
