8" x 1-1/2" 60 Grit Diamond Nova Resin Soft Grinding Wheel for Lapidary & Glass

The 8" x 1-1/2" 60 Grit Diamond Nova Resin Soft Grinding Wheel is a powerful coarse shaping and material-removal soft wheel engineered for standard 8-inch vertical cabbing units and bench grinding machinery. Built with a proprietary coarse resin-bonded diamond matrix over a thick, resilient foam cushion mounted on a precision-balanced plastic hub, this wheel conforms smoothly to curved gemstone contours, eliminating flat spots and harsh facet lines while delivering aggressive, chatter-free stock removal on agate, jasper, quartz, jade, ceramic, and art glass.

Key Features

• Resilient Foam Cushioning: Cushioned core conforms effortlessly to domed cabochons and curved silhouettes, preventing gouges and flat spots.
• Aggressive Coarse 60-Grit Diamond Matrix: Formulated with concentrated 60-grit monocrystalline diamonds in a durable resin bond for rapid stock removal with minimal chipping.
• Precision Balanced Plastic Hub: Guarantees true-running, wobble-free rotation at standard cabbing speeds of 1400–1800 RPM.
• Standard 1" Arbor with Reducer Bushings: Bored to 1" and supplied with precision bushing spacers to adapt seamlessly to 3/4", 5/8", and 1/2" machine arbors.

Applications

• Gemstone Cabbing & Rapid Shaping: Rough shaping and contouring cabochons and mineral specimens in agate, jasper, quartz, petrified wood, and jade.
• Glass Cold Working & Beveling: Rapid stock removal, edge truing, and beveling on fused glass panels and art glass sculptures.
• Ceramic & Specimen Leveling: Grinding specimen backs, fossil slabs, and dense technical ceramics flat and uniform.

Operating Guidelines

• Always operate with adequate continuous water coolant; never run resin-bonded diamond wheels dry.
• Use light, uniform hand pressure; letting the diamond cut freely prevents premature resin wear and heat buildup.
• New wheels have a brief initial break-in period; use a scrap piece of agate or glass with plenty of water to condition the diamond face.
