6" x 1-1/2" 4-Grit Set Diamond REZ Resin Grinding Wheel for Lapidary & Glass

The 6" x 1-1/2" 4-Grit Set Diamond REZ Resin Soft Grinding Wheels is a premium pre-polishing and fine-smoothing collection engineered for lapidary cabochon cutters, gemstone enthusiasts, and studio glass artisans. Utilizing advanced REZ resin-bond technology with a dense, proprietary diamond formulation over a thick, high-rebound cushioning foam layer, this 4-wheel progression ensures rapid scratch elimination, smooth curve compliance, and an exceptional high-luster pre-polish across agates, jaspers, quartz, opals, and glass.

Set Inclusions & Progressive Grit Sequence

• 280 Grit (Coarse Smoothing): Swiftly erases coarse grinding marks, flat spots, and ridges left by electroplated or sintered hard wheels.
• 600 Grit (Fine Smoothing): Removes sub-surface micro-scratches, refines cabochon dome curvature, and imparts an even satin finish.
• 1200 Grit (Initial Pre-Polish): Imparts an ultra-smooth, translucent surface on semi-precious stones and glass edges.
• 3000 Grit (High-Luster Pre-Polish): Develops rich color depth and an intense initial gloss, readying stones for final buffing.

Key Features

• Advanced REZ Resin Bond Formulation: Superior diamond retention and thermal resistance provide exceptionally long working life without premature shedding.
• High-Rebound Thick Foam Cushioning: Effortlessly absorbs hand pressure, conforms to tight cabochon 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 4-Wheel Workflow Kit: Cost-effective professional progression covering every essential stage from initial smoothing to brilliant pre-polish.

Applications

• High-End Lapidary Cabbing: Pre-polishing cabochons of agate, jasper, turquoise, quartz, opal, jade, and petrified wood.
• 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.
