8" x 2" 600 Grit Diamond Resin Grinding Wheel – REZ Premium Soft Wheel for Lapidary Polishing & Glass Grinding

The 8" x 2" 600 Grit Diamond Resin Grinding Wheel (REZ Premium Soft Wheel) is precision-engineered for essential pre-polishing surface refining, eliminating fine micro-scratches, and bringing cabochon contours to an ultra-smooth satin luster before final high-gloss polishing. Built with a high-density monocrystalline diamond matrix embedded in an advanced thermo-setting resin layer over an impact-absorbing closed-cell foam cushion, this heavy-duty 2-inch wide soft wheel hugs curved contours, eliminating flat spots and harsh edge facets.

Key Features

• Closed-Cell Flexible Foam Cushion: Thick resilient cushion layer conforms to convex cabochon domes and curved workpieces, preventing chatter marks and facet flats.
• Ultra-Fine 600-Grit Diamond Formulation: Delivers flawless pre-polish smoothing, completely erasing 280/325-grit sanding marks and establishing a uniform semi-reflective sheen.
• Heavy-Duty Precision Plastic Hub: True-running, corrosion-proof composite hub guarantees balanced rotation and eliminates vibration at standard cabbing speeds.
• Extra-Wide 2" Working Surface: Full 2-inch width provides substantial surface area for large cabochons, slab edges, and broad art glass surfaces.
• 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 Cabochon Pre-Polishing & Cabbing: Essential pre-polishing stage for agate, jasper, chalcedony, quartz, jade, turquoise, and petrified wood.
• Glass Cold Working & Beveling: Fine edge smoothing, facet blending, and satin surface preparation on decorative and art glass.
• Specimen Finishing: Pre-polish surface preparation on mineral slabs, fossil displays, and ornamental stones.

Technical Specifications

• Grit: 600 Grit (Fine Pre-Polishing & Scratch Elimination)
• Bond Type: Resin Bond with Flexible Closed-Cell Cushion
• Hub Material: Precision Injection-Molded Polymer Core
• Arbor Size: 1 inch (includes 3/4", 5/8", 1/2" reducer bushings)
• Recommended Operating Speed: 1400–1800 RPM

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 full 2-inch 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.
