Flexible Diamond Sanding Belts

Professional flexible diamond sanding belts for belt sanders, lapidary combination machines, and industrial finishing equipment. Available in 2400x50mm and 2130x60mm/100mm sizes across 240 to 1800 grit in dot and arrow diamond patterns for optimized coolant flow and swarf removal. The flexible diamond abrasive backing conforms smoothly to both curved and flat surfaces for consistent cutting performance throughout the belt's service life.

Frequently Asked Questions

  • Q: What is the difference between dot and arrow diamond patterns?
    A: Both patterns create open channels between diamond segments for coolant circulation and swarf evacuation. The dot pattern provides multi-directional, uniform coverage across the workpiece. The arrow pattern creates directional channels that accelerate swarf expulsion in high-throughput grinding setups. Both deliver excellent results in wet lapidary grinding.
  • Q: Should flexible diamond belts be used wet?
    A: Yes — always operate flexible diamond belts with continuous water coolant. Wet sanding prevents thermal degradation of the bond, extends diamond belt life, and produces flawless, scratch-free finishes on hard lapidary materials and glass.
