75mmx36mm 240 Grit Flexible Diamond Sanding Belt – Efficient Polishing & Grinding for Hard Materials

Overview: The 75mm x 36mm (236mm length) 240 Grit Flexible Diamond Sanding Belt is crafted for 75mm (3-inch) diameter expanding rubber drums, hand-held pipe sanders, and lapidary grinders. Featuring precision electroplated 240-grit industrial diamond abrasive on a flexible waterproof backing, this belt smoothly transitions surfaces from rough grinding to fine smoothing across stones, glass, ceramics, and hard alloys.

Key Features

• 240 Grit Medium-Fine Smoothing: Uniformly eliminates coarser 120-grit scratch patterns while preparing surfaces for pre-polish stages.
• Engineered for 75mm Expanding Drums: 236mm true developed circumference provides a precise slip-fit that grips securely during centrifugal drum expansion.
• Waterproof Synthetic Backing: Designed for continuous wet operation with water coolants, resisting edge fraying and dimensional stretching.
• Precision Butt-Joint Seam: Smooth, seamless joint ensures vibration-free running and flawless workpiece surface finishes.

Applications

• Fine pre-polish cabochon smoothing and facet surface prep on agate, jade, quartz, and jasper
• Glass edge fine smoothing, arrising, and glass craft bevel finishing
• Ceramic and porcelain tile edge smoothing and contour refining
• Precision metal deburring, weld smoothing, and coating surface refinement

Operating Guidelines

• Coolant: Use with continuous water flood or coolant spray to flush fine slurry and extend diamond abrasive life.
• Speed: Recommended surface speed 3,000 to 5,500 SFPM with light to moderate pressure.
