6" x 1-1/2" 180 Grit Lapidary Diamond Hard Flat Grinding Wheel

The 6" x 1-1/2" 180 Grit Lapidary Diamond Hard Flat Grinding Wheel is a precision-engineered rough-to-intermediate shaping wheel designed for standard 6-inch vertical cabbing units and arbor grinding machines. Manufactured with a seamless, precision-machined solid steel core and an electroplated layer of uniform monocrystalline diamonds, this hard flat wheel delivers true-running performance and rapid stock removal without surface deflection. It is ideal for grinding flat facets, preforming cabochon contours, and squaring edges on hard materials including agate, jasper, quartz, jade, ceramic, and glass.

Key Features

• Precision Steel Core Construction: Rigid, balanced steel body eliminates runout, providing absolute rim flatness and vibration-free rotation at 1400–1800 RPM.
• Heavy-Duty Electroplated Diamond Bond: Premium 180-grit diamond particles are nickel-bonded securely to the cylindrical face, ensuring high cutting aggression and resistance to diamond stripping.
• Intermediate Stock Removal & Shaping: Bridges coarse rough grinding and fine pre-polishing, quickly removing 80/100-grit scratches while holding strict dimensional tolerances.
• True Flat Profile: Delivers sharp 90-degree corners and flat, uniform grinds on slabs, preforms, and cabochon girdles.
• 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 & Preforming: Smoothing cabochon dome contours and calibrating girdle thickness on agate, jasper, quartz, petrified wood, and jade.
• Glass Cold Working & Beveling: Truing saw cuts, edge beveling, and shaping cold-worked art glass components.
• Ceramic & Mineral Sizing: Grinding specimen backs, fossil slabs, and dense technical ceramics flat and true.

Technical Specifications

• Diameter: 6 inches (150 mm)
• Width: 1-1/2 inches (38 mm)
• Grit: 180 Grit (Medium Shaping)
• Core Material: Solid Steel
• Bond Type: Electroplated Diamond
• Arbor Size: 1 inch (includes 3/4", 5/8", 1/2" reducer bushings)
• Recommended Operating Speed: 1400–1800 RPM

Operating Guidelines

• Always operate with adequate continuous water coolant to keep the work piece cool and flush swarf from the diamond surface.
• Apply light to moderate, uniform hand pressure; let the diamond cut freely without forcing the workpiece against the steel core.
• Avoid grinding on the corner edges to prevent premature diamond stripping along the rim shoulder.
