6" x 1-1/2" 6-Grit Set Diamond REZ Resin Grinding Wheel for Lapidary & Glass

The 6" x 1-1/2" 6-Grit Set Diamond REZ Resin Soft Grinding Wheels is a premium-tier, resilient pre-polishing and fine-finishing wheel progression engineered for high-performance lapidary shops, commercial gemstone cabbers, and precision glass cold workers. Utilizing advanced REZ resin-bond technology with a dense, proprietary diamond formulation over a thick, high-rebound cushioning foam layer, this 6-wheel set provides unmatched conformability, aggressive yet scratch-free pre-polishing, and exceptional wear resistance across cabochons and mineral slabs.

Set Inclusions & Progressive Grit Sequence

• 280 Grit (Coarse Smoothing): Swiftly erases grinding marks, flat spots, and ridges left by electroplated or sintered hard wheels.
• 600 Grit (Fine Smoothing): Removes sub-surface micro-fractures, refines cabochon dome curvature, and imparts a silky 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 deep color clarity 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

• Advanced REZ Resin Bond Formulation: Superior diamond retention and heat resistance deliver significantly longer working life compared to standard soft wheels.
• High-Rebound Thick Foam Cushioning: Effortlessly absorbs hand pressure, conforms to tight curves, and eliminates micro-faceting or edge chipping.
• Precision-Balanced Composite Hub: Machined 1-inch core runs true without rotational wobble, ensuring maximum contact stability and minimal hand fatigue.
• Universal 1" Arbor with Reducer Bushings: Includes precision reducer bushings to fit 3/4", 5/8", and 1/2" standard lapidary machine shafts.
• Complete 6-Wheel Workflow Kit: Cost-effective full finishing progression covering every stage from initial smoothing to brilliant pre-polish.

Applications

• High-End Lapidary Cabbing: Pre-polishing high-value gemstones including Australian opal, turquoise, jade, tourmaline, agate, and jasper.
• Glass Cold Working & Art Glass: Smoothing ground glass edges, removing punty marks, and pre-polishing studio glass sculptures.
• Mineral & Fossil Specimen Finishing: Polishing delicate fossil surfaces, ammonites, and fine mineral display specimens.

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.
