100mmx50mm Flexible Diamond Sanding Belt ¨C Efficient Polishing & Grinding for Hard Materials

Overview: The 100mm x 50mm Flexible Diamond Sanding Belt – Efficient Polishing & Grinding for Hard Materials (314mm x 50mm circumference) is a heavy-duty flexible diamond abrasive belt engineered for wet grinding, surface leveling, and fine polishing on expanding rubber drums and finishing machines. Featuring electroplated diamond particles bonded to a tear-resistant backing, it offers rapid material removal and extended belt longevity across glass, natural stone, technical ceramics, and hard metals.

Key Features

• Durable Electroplated Diamond Surface: Delivers sharp, aggressive cutting and consistent scratch patterns across all grit stages.
• Expanded Drum Fit (100mm Dia. / 314mm Length): Sized for standard 100mm diameter expanding drums with a wide 50mm contact face.
• Heavy-Duty Flexible Backing: Flexes smoothly over curved surfaces and contoured profiles without peeling or edge cracking.
• Seamless Precision Joint: Engineered splice guarantees smooth, chatter-free rotation under steady hand pressure.

Applications

• Glass cold-working, curved edge smoothing, and bottle neck contour grinding
• Lapidary cabochon shaping, gemstone pre-polishing, and mineral specimen finishing
• Ceramic profiling, hard porcelain edge finishing, and carbide blending

Operating Guidelines

• Coolant: Always use with adequate water coolant or wet spray to flush debris and maximize diamond durability.
• Mounting: Ensure the belt is properly centered on the expanding drum before bringing to operating speed.
• Speed: Recommended operating speed 2,500 to 5,000 SFPM.
