8" x 2" 6-Grit Set Diamond REZ Resin Grinding Wheel for Lapidary & Glass

The 8" x 2" 6-Grit Set Diamond REZ Resin Soft Grinding Wheels is the ultimate commercial-capacity pre-polishing and fine-finishing wheel progression engineered for high-volume lapidary production studios, master cabochon cutters, and professional glass artists. Featuring an extra-wide 2-inch width and an 8-inch diameter, this heavy-duty 6-wheel set combines advanced REZ resin-bond diamond formulations with high-rebound cushioning foam, delivering maximum surface area coverage, high surface speed, and aggressive yet scratch-free pre-polishing across large mineral slabs, cabochons, and glassware.

Set Inclusions & Progressive Grit Sequence

• 280 Grit (Coarse Smoothing): Swiftly erases coarse tool marks, saw ridges, and aggressive scratches left by electroplated or sintered hard wheels.
• 600 Grit (Fine Smoothing): Eliminates micro-scratches, refines cabochon dome curvature, and establishes a uniform satin finish.
• 1200 Grit (Initial Pre-Polish): Imparts an ultra-smooth, translucent surface on semi-precious stones and glass edges.
• 3000 Grit (Intermediate Pre-Polish): Develops rich color depth and an intense initial gloss across mineral matrices.
• 8000 Grit (Fine Pre-Polish): Delivers brilliant, optical-grade luster on chalcedony, agate, quartz, jade, and opal.
• 14000 Grit (Final Optical Pre-Polish): Imparts an extraordinary mirror pre-polish, reducing final cerium oxide buffing time to seconds.

Key Features

• Extra-Wide 2" Working Width: Covers extensive surface area per rotation, dramatically reducing processing time on large mineral slabs, architectural glass, and large cabochons.
• High-Velocity 8" Diameter: Maximizes SFPM (surface feet per minute) for rapid, effortless cutting action with minimal hand fatigue.
• Advanced REZ Resin Bond Formulation: Superior diamond retention and heat resistance provide significantly longer working life compared to standard soft wheels.
• High-Rebound Thick Foam Cushioning: Absorbs hand pressure, conforms smoothly to curved contours, and prevents flat-spotting or edge chipping.
• Universal 1" Arbor with Reducer Bushings: Each wheel features a precision 1-inch arbor hole and includes reducer bushings to fit 3/4", 5/8", and 1/2" shafts.
• Complete 6-Wheel Workflow Kit: Cost-effective professional progression covering every critical smoothing and pre-polishing stage.

Applications

• Large Lapidary Cabbing & Slabs: Smoothing and high-grade pre-polishing of large agate, jasper, quartz, jade, opal, and petrified wood specimens.
• Glass Cold Working & Art Glass: Edge beveling, punty scar smoothing, and surface finishing on cast, blown, or fused glass.
• Mineral & Fossil Specimen Preparation: Finishing curved display faces on ammonites, geodes, and decorative mineral carvings.

Operating Guidelines

• Always operate with continuous, steady water coolant to lubricate the wheel face, flush mineral swarf, and prevent heat buildup in the resin bond.
• Apply light to gentle hand contact; excessive pressure causes premature resin wear without improving cutting speed.
• Never dig sharp gemstone corners or points into the wheel face to prevent gouging the flexible resin layer.
