200mmx65mm 1500Grit Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 200mm x 65mm (628mm length) 1500 Grit Flexible Diamond Sanding Belt is tailored for standard 200mm (8-inch) expandable rubber drums, wet lapidary cabbing units, and glass edge polishing equipment. Engineered with electroplated 1500-grit micro-diamond crystals securely anchored to a flexible, waterproof backing, it delivers smooth pre-polishing and eliminates sub-surface micro-scratches across hard stones, glass, and composites.

Key Features

• Micro-Diamond 1500 Grit Pre-Polish: Blends fine scratches and establishes a silky satin pre-polish on cabochons and glass bevels.
• Engineered for 200mm (8") Expanding Drums: 628mm developed length ensures a secure, slip-free friction fit under centrifugal drum expansion.
• Reinforced Waterproof Backing: Designed to withstand heavy continuous water flow, chemical coolants, and high mechanical tension.
• Precision Butt-Joint Seam: Smooth, seamless joint prevents chatter and ensures vibration-free tracking at high operating speeds.

Applications

• Lapidary gemstone pre-polishing, cabochon refinement, and specimen display finishing
• 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: Use with continuous water flood or coolant spray to flush fine swarf and protect diamond plating.
• Tension & Tracking: Mount securely onto 200mm expanding drums before reaching full operational RPM.
• Speed: Recommended surface speed 3,000 to 5,500 SFPM.
