8" x 1.5" 60 Grit Diamond Hard Flat Grinding Wheel for Hard Materials

The 8" x 1.5" 60 Grit Diamond Hard Flat Grinding Wheel is constructed with a heavy-duty, seamless solid steel core and an aggressive electroplated diamond rim. Built for rapid material removal, primary cabochon roughing, and bulk stock shaping on tough lapidary materials including gemstones, rocks, glass, ceramics, and porcelain. Engineered for vibration-free running on standard 8" arbor machines.

Key Features

• Solid Seamless Steel Core: Heavy-duty steel body ensures true-running concentricity and eliminates wheel vibration.
• Aggressive Electroplated Diamond Rim: Uniform 60-grit diamond plating delivers rapid, efficient material hogging and long edge durability.
• True Flat Profile: Perfectly flat grinding face prevents dishing or crowning during shaping and faceting pre-forming.
• Universal 1" Arbor: Standard 1-inch inner bore fits standard lapidary cabbing machines (compatible with 3/4", 5/8", and 1/2" reducer bushings).

Applications

• Lapidary & Gemstones: Aggressive pre-forming and rough material removal on agate, jasper, quartz, jade, and petrified wood slabs.
• Glass Cold Working: Rapid edge grinding, gross dimensioning, and bevel pre-forming on thick art glass and plate glass.
• Ceramic & Porcelain: Heavy shaping, stock reduction, and edge beveling on dense technical ceramics and mineral specimens.

Technical Specifications

• Diameter: 8 inches (200 mm)
• Width: 1.5 inches (38 mm)
• Grit: 60 Grit (Coarse Roughing / Rapid Stock Removal)
• Bond Type: Electroplated Diamond
• Core Material: Solid Steel
• Arbor Size: 1 inch (compatible with reducer bushings)
• Recommended Operating Speed: 1400–1800 RPM

Operating Guidelines

• Continuous Water Coolant Required: Always operate with adequate water flow to flush grinding swarf and keep diamond particles cool.
• Apply light, consistent workpiece pressure across the wheel face to prevent localized grooving.
