8" x 2" 50000 Grit Diamond Resin Grinding Wheel – Nova Soft Wheel for Precision Glass & Stone Grinding

The 8" x 2" 50000 Grit Diamond Resin Grinding Wheel (Nova Premium Soft Wheel) is an industry-standard lapidary soft grinding wheel engineered for final mirror polishing, ultra-fine scratch elimination, and optical-grade high-gloss finishing on gemstone cabochons, glass cold work, and mineral specimens. Built with premium resin-bonded diamond abrasives uniformly dispersed over a resilient closed-cell foam cushion mounted on a heavy-duty balanced plastic hub, it effortlessly conforms to curved stone surfaces to eliminate flats and chatter marks.

Key Features

• Resilient Foam Cushioning: Thick cushion layer conforms smoothly to cabochon contours, preventing flat spots and ensuring uniform surface contact across all curved workpieces.
• Ultra-Fine 50000-Grit Diamond Formulation: Produces an immaculate optical mirror polish on hard gemstones, facet contours, and glass creations.
• Heavy-Duty Precision Plastic Hub: Precision molded plastic core ensures smooth, vibration-free operation at standard cabbing speeds.
• Wide 2" Working Width: Provides a broad working surface for large slabs, wide cabochons, and extensive mineral specimens.
• Superior Wet Grinding Performance: Engineered for continuous water coolant operation to maintain cool cutting and prevent resin glazing.
• Standard 1" Arbor with Reducer Bushings: Precision 1-inch bore supplied with reducer bushings to fit 3/4", 5/8", and 1/2" shafts.

Applications

• Lapidary Cabochon Contouring: Final mirror polishing on agate, jasper, jade, quartz, turquoise, and petrified wood.
• Glass Cold Working & Beveling: Optical mirror polishing and edge refinement on decorative glass and crystal sculptures.
• Ceramic & Specimen Prep: Precision high-gloss surface polishing on ceramics and mineral display pieces.

Operating Guidelines

• Always operate with continuous water lubrication to flush slurry and prevent thermal damage to the resin matrix.
• Apply light, gentle pressure across the wheel face; excessive force causes premature wear without improving polish quality.
• Move workpieces continuously across the wheel to ensure even surface wear and maintain concentric wheel balance.
