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

The 8" x 1-1/2" 6-Grit Set Diamond Nova Resin Soft Grinding Wheel is a comprehensive cabbing and polishing set engineered for standard 8-inch vertical cabbing machines and bench grinding units. Each wheel features a proprietary resin-bonded diamond matrix backed by a thick, resilient foam cushion mounted on a precision-balanced plastic hub. This complete 6-wheel progression effortlessly contours to convex cabochons, eliminating flats and scratches while taking raw gemstones and art glass smoothly from fine shaping to a high-gloss polish.

Key Features

• Complete 6-Wheel Progression: Includes six essential grits (280, 600, 1200, 3000, 8000, and 14000 Grit) to handle every stage from intermediate smoothing through mirror finishing.
• Resilient Foam Cushioning: Conforms smoothly to cabochon dome contours and curves, absorbing surface pressure and preventing accidental flat spots.
• Premium Resin Diamond Bond: High-concentration diamond micro-particles bonded in durable resin deliver consistent, streak-free polishing across diverse lapidary materials.
• Balanced Plastic Hub: Precision-molded core guarantees true running, eliminates wobble, and operates vibration-free at 1400–1800 RPM.
• Standard 1" Arbor with Reducer Bushings: Bored to 1" and supplied with precision bushing sets to fit 3/4", 5/8", and 1/2" machine arbors.

Applications

• Gemstone Cabbing & Polishing: Smoothing and high-luster polishing on agate, jasper, quartz, jade, turquoise, and opal cabochons.
• Glass Cold Working: Refining cut edges, beveling borders, and polishing curved art glass sculptures.
• Ceramic & Specimen Finishing: Pre-polishing and final buffing on mineral slabs and dense technical ceramics.

Operating Guidelines

• Always operate with adequate continuous water coolant; never run resin-bonded diamond wheels dry.
• Use light, uniform hand pressure; allowing the diamond to cut freely prevents overheating and maximizes wheel lifespan.
• Maintain a dedicated water drip or spray nozzle per wheel to avoid cross-contamination of coarse grit onto fine polishing wheels.
