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

The 6" x 1.5" 60 Grit Diamond Hard Flat Grinding Wheel is engineered with a solid, seamless steel core and a premium electroplated diamond rim. Designed for aggressive material removal, initial cabochon roughing, and precision edge beveling on tough materials including gemstones, rocks, glass, ceramics, and porcelain. Built for vibration-free running on standard lapidary cabbing arbors.

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 fast, efficient stock removal and long-lasting edge stability.
• 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: Fast rough shaping and pre-forming of agate, jasper, quartz, jade, and petrified wood cabochons.
• Glass Cold Working: Rapid edge grinding, dimensioning, and bevel pre-forming on art glass and thick plate glass.
• Ceramic & Porcelain: Clean shaping and contour beveling of dense technical ceramics and mineral specimens.
