6"x1.5" Diamond Flexible Abrasive Finishing Sanding Belts For Polishing Glass Ceramic Porcelain Lapidary and Stone

Overview: The 6" x 1.5" (479mm x 38mm) Flexible Diamond Sanding Belt is specifically manufactured to run on 6" diameter expanding rubber drums commonly found on lapidary cabbing arbors, glass finishing lathes, and contour sanders. Built with high-purity electroplated industrial diamond crystals on a tough, waterproof backing, this belt delivers rapid stock removal and exceptionally consistent surface prep under continuous wet grinding.

Key Features

• Precision Fit for 6" Expanding Drums: True 479mm perimeter (approx. 18.85" circumference) expands tightly over standard 6" x 1.5" rubber drums during operation.
• Full Range of Grits & Patterns: Available in Dot and Arrow diamond patterns from coarse 60 Grit calibration down to 1800 Grit ultra-fine pre-polishing.
• Waterproof High-Strength Backing: Resists water soaking, chemical coolants, and edge tearing under sustained workshop use.
• Smooth Flat Seam: Precision joint construction prevents bumping, vibration, and chatter marks on delicate gemstone or glass surfaces.

Applications

• Lapidary cabochon roughing, dome pre-shaping, and edge profiling on expanding wheels
• Glass cold-working, vase and bowl rim beveling, and art glass smoothing
• Hard mineral and fossil preparation, leveling flat cuts, and contour blending
• Ceramic tile edge chamfering and hard composite deburring

Operating Guidelines

• Coolant: Always operate with adequate water coolant to lubricate the cut, flush away sludge, and prolong diamond life.
• Drum Mount: Slide belt onto expanding rubber drum while stationary; the drum expands with centrifugal force to lock the belt securely at speed.
• Speed: Recommended operating speed 1,200 to 1,800 RPM on 6" arbor setups.
