8" x 2" 4-Grit Set Diamond REZ Resin Grinding Wheel for Lapidary & Glass

The 8" x 2" 4-Grit Set Diamond REZ Resin Soft Grinding Wheels provides a heavy-duty, commercial-grade fine-smoothing and pre-polishing solution for commercial lapidary studios, production cabbers, and glass artisans. Designed with an expansive 2-inch wide working face, high-resilience thick foam backing, and proprietary REZ resin-bonded diamond formulation, this 4-wheel progression delivers high surface throughput, exceptional curve compliance, and rapid scratch elimination across quartz, jade, agate, jasper, opals, and art glass.

Set Inclusions & Progressive Grit Sequence

• 280 Grit (Coarse Smoothing): Rapidly removes coarse scratches, flat spots, and faceting lines left by hard metal/sintered wheels.
• 600 Grit (Fine Smoothing): Smooths stone domes, refines contours, and eliminates micro-scratches with an even satin surface.
• 1200 Grit (Initial Pre-Polish): Creates an ultra-fine, silky pre-polish that prepares semi-precious gems and glass for brilliant finishing.
• 3000 Grit (High-Luster Pre-Polish): Generates a rich reflective gloss, bringing out true natural color and optical depth before final buffing.

Key Features

• Expansive 2" Broad Grinding Face: Offers greater surface area for rapid material processing on large cabochons, slab faces, and sculptures.
• Advanced REZ Resin Bond Formulation: Superior diamond retention and thermal resistance prevent premature diamond loss and wheel glazing.
• High-Rebound Thick Foam Cushioning: Conforms dynamically to domed cabochons and curved contours, preventing flat spots and micro-chipping.
• Heavy-Duty Precision-Balanced Composite Hub: Machined 1-inch core runs true without vibration, ensuring ultra-smooth grinding and operator comfort.
• Universal 1" Arbor with Reducer Bushings: Includes precision bushings to adapt effortlessly to 3/4", 5/8", and 1/2" machine arbors.

Applications

• Production Lapidary Cabochon Finishing: Rapid pre-polishing of agate, jasper, turquoise, jade, opal, quartz, and petrified wood.
• Glass Cold Working & Art Glass: Bevel smoothing, removing ground marks, and edge pre-polishing on art glass and crystal.
• Fossil & Large Specimen Prep: Finishing large fossil cross-sections, nodules, and collector mineral specimens.

Operating Guidelines

• Always use a continuous, generous flow of clean water coolant to keep the wheel cool and clear grinding debris.
• Use light to moderate hand pressure; letting the diamond abrasive work naturally extends wheel longevity.
• Avoid digging sharp points or edges into the wheel face to maintain an even, flat working surface.
