The 8" x 1-1/2" Diamond Nova Resin Soft Grinding Wheel is a high-performance, extra-large diameter flexible lapidary cabbing wheel engineered for rapid scratch removal, pre-polishing, and precision contour finishing on gemstones, minerals, and studio glass. Combining an 8-inch diameter for greater surface speed and grinding area with a resilient, shock-absorbing resin bond matrix, this soft wheel delivers exceptionally smooth, flat-spot-free finishes on cabochons of all sizes.

Key Features

  • Cushioned Resin-Bond Matrix: Flexible resin layer conforms naturally to curved cabochon domes, eliminating flat spots, micro-faceting, and chipping.
  • Expanded 8" Grinding Diameter: Delivers higher SFPM (surface feet per minute) and a larger working surface than 6" wheels, smoothing large stones and glass projects with greater efficiency.
  • Uniform Diamond Dispersion: Premium synthetic diamond particles are homogeneously distributed through the resin layer, providing consistent, repeatable cutting throughout wheel life.
  • Seamless Scratch Elimination: Rapidly removes coarse grinding marks left by hard electroplated or sintered wheels, establishing a uniform satin pre-polish ready for final polish.
  • Universal 1" Arbor with Reducer Bushings: Includes precision reducer bushings to fit 3/4", 5/8", and 1/2" standard lapidary machine shafts.
  • Full Progressive Grit Range: Available from aggressive 60 grit for rapid smoothing up to 50,000 grit for mirror-like optical polishing.

Applications

  • Lapidary Cabbing & Pre-Polishing: Smoothing and pre-polishing large agate, jasper, quartz, jade, turquoise, and opal cabochons.
  • Glass Cold Working: Blending ground bevels, smoothing punty marks, and finishing fused glass artworks.
  • Fossil & Mineral Specimen Finishing: Polishing curved faces of ammonites, petrified wood slabs, and contoured mineral specimens.

Technical Specifications

  • Diameter: 8 inches (203 mm)
  • Width: 1-1/2 inches (38 mm)
  • Arbor Size: 1 inch (includes 3/4", 5/8", 1/2" reducer bushings)
  • Hub Construction: High-Impact Balanced Composite Core with Resilient Foam Cushion
  • Bond Type: Resilient Resin Bond Diamond Matrix
  • Available Grits: 60, 140, 280, 325, 600, 1200, 3000, 8000, 14000, 50000
  • Recommended Operating Speed: 1400–1800 RPM

Operating Guidelines

  • Always operate with a continuous, steady water drip to lubricate the wheel face, flush mineral swarf, and prevent heat buildup.
  • Apply light to gentle hand contact; excessive pressure does not increase cutting speed and may cause premature resin wear.
  • Never dig sharp gemstone edges, points, or corners into the wheel surface to protect the resilient resin matrix from gouging.
