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

The 8" x 2" 6-Grit Set Diamond Nova Resin Soft Grinding Wheels is a commercial-grade, full-spectrum pre-polishing and fine-finishing system designed for high-capacity lapidary shops, gemstone cabbing studios, and glass artists. Featuring an extra-wide 2-inch abrasive width and an 8-inch diameter, this complete 6-wheel progression delivers maximum surface area coverage, high surface speed, and uniform cushioning, guiding workpieces effortlessly from coarse scratch cleanup all the way to a brilliant, near-mirror pre-polish across large mineral slabs, cabochons, and glassware.

Set Inclusions & Progressive Grit Sequence

• 280 Grit (Coarse Smoothing): Rapidly erases deep saw marks, flat spots, and aggressive scratches left by electroplated or sintered wheels.
• 600 Grit (Fine Smoothing): Eliminates micro-scratches, refines dome curvature, and establishes a uniform satin texture.
• 1200 Grit (Initial Pre-Polish): Imparts an ultra-smooth, translucent surface on semi-precious stones and glass edges.
• 3000 Grit (Intermediate Pre-Polish): Produces a high-clarity gloss, significantly reducing buffing time.
• 8000 Grit (Fine Pre-Polish): Delivers brilliant gloss and color depth across quartz, chalcedony, agate, and hard gemstones.
• 14000 Grit (Final Optical Pre-Polish): Produces a mirror-like optical finish, preparing workpieces for final cerium oxide or diamond paste buffing.

Key Features

• Extra-Wide 2" Working Width: Covers extensive surface area per rotation, dramatically reducing shaping time on large slabs and art glass.
• High-Velocity 8" Diameter: Maximizes SFPM (surface feet per minute) for rapid, effortless cutting action with minimal hand fatigue.
• Resilient Resin-Bond Cushioning: Soft flexible matrix absorbs shock, conforms to curved cabochon crowns, and eliminates flat spots and micro-facets.
• Homogeneous Diamond Dispersion: Uniformly embedded synthetic diamond particles continuously reveal fresh cutting edges as the wheel gently wears.
• 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 Finishing Progression: All-in-one comprehensive solution 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.

Technical Specifications

• Set Quantity: 6 Wheels (280, 600, 1200, 3000, 8000, 14000 Grit)
• Hub Construction: High-Impact Balanced Composite Core with Resilient Foam Cushion
• Bond Type: Resilient Resin Bond Diamond Matrix
• Recommended Operating Speed: 1400–1800 RPM

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.
