8" x 1-1/2" 8000 Grit Diamond Resin Grinding Wheel – REZ Premium Soft Wheel for Lapidary Polishing & Glass Grinding

The 8" x 1-1/2" 8000 Grit Diamond Resin Grinding Wheel (REZ Premium Soft Wheel) is precision-engineered for the ultra-fine optical polishing stage, producing an extraordinary wet-look, mirror-bright polish on cabochons and fine glass workpieces. Built with sub-micron monocrystalline diamond particles uniformly dispersed throughout a premium resin matrix over a resilient closed-cell foam cushion, this versatile soft wheel conforms smoothly to curved contours, eliminating flat spots and harsh edge facets.

Key Features

• Closed-Cell Flexible Foam Cushion: Resilient cushion layer conforms naturally to convex cabochon domes and curved workpieces, preventing chatter marks and facet flats.
• Ultra-Fine 8000-Grit Diamond Formulation: Produces a stunning mirror-gloss polish with crystal-clear depth and zero residual haze or swirl marks.
• Heavy-Duty Precision Plastic Hub: True-running, corrosion-proof composite hub guarantees balanced rotation and eliminates vibration at standard cabbing speeds.
• Standard 1-1/2" Working Surface: Popular 1-1/2" face width fits standard 8-inch cabbing machine arbor configurations and multi-wheel shaft setups.
• Superior Wet Grinding Life: Designed for continuous water coolant operation to maintain cool cutting, flush swarf, 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" cabbing machine shafts.

Applications

• Lapidary Mirror Polishing & Cabbing: Final optical-grade polish stage for agate, jasper, chalcedony, quartz, jade, turquoise, and petrified wood.
• Glass Cold Working & Beveling: Ultra-fine mirror luster refinement on decorative and art glass, crystal sculptures, and optical edges.
• Specimen Finishing: Museum-quality gloss surface polishing on mineral slabs, fossil displays, and ornamental stones.

Operating Guidelines

• Always use continuous water lubrication to flush ground slurry and keep the diamond-resin matrix cool.
• Apply light to moderate, uniform pressure across the wheel face; excessive force causes premature wheel wear without improving cutting speed.
• Keep workpieces moving continuously across the wheel to ensure even surface wear and maintain concentric wheel balance.
