6"x2.5" Diamond Flexible Abrasive Finishing Sanding Belts For Polishing Glass Ceramic Porcelain Lapidary and Stone

Overview: The 6" x 2.5" (479mm x 64mm) Flexible Diamond Sanding Belt is engineered for heavy-duty 6" wide expandable rubber drums on lapidary cabbing arbors, glass finishing units, and wide-drum contour grinders. Premium electroplated diamond abrasive securely anchored to a flexible, high-tensile waterproof backing delivers broad contact area, rapid stock removal, and uniform wet grinding without delamination.

Key Features

• Engineered for 6" x 2.5" Expanding Drums: True 479mm length (approx. 18.85" circumference) expands securely onto standard 6" x 2.5" rubber wheels at operational RPM.
• Full Range of Grits & Patterns: Available in Dot and Arrow patterns across grit sizes from coarse 60 Grit calibration down to 1800 Grit ultra-fine pre-polishing.
• Heavy-Duty Waterproof Backing: Resists continuous water spray, coolants, and lateral edge loading during intensive workshop grinding.
• Precision Low-Profile Seam: Smooth, seamless joint prevents chatter, bouncing, or surface gouging on delicate gemstones and optical glass.

Applications

• Lapidary gemstone roughing, large cabochon dome smoothing, and slab edge shaping
• Glass cold-working, rim leveling, sculptural glass smoothing, and bottle finishing
• Engineered stone and marble tile edge rounding and bevel prep
• Hard ceramic contouring and thermal spray coating surface prep

Operating Guidelines

• Coolant: Always operate with continuous water coolant to keep diamond cool, flush away slurry, and maintain cutting speed.
• Drum Mount: Mount onto stationary 6" x 2.5" expanding drum; centrifugal force secures the belt firmly when the arbor rotates.
• Speed: Recommended operating speed 1,200 to 1,800 RPM.
