6" x 1-1/2" 100 Grit Lapidary Diamond Hard Flat Grinding Wheel for Gemstone Shaping

The 6" x 1-1/2" 100 Grit Lapidary Diamond Hard Flat Grinding Wheel is an essential electroplated shaping wheel designed for standard 6-inch lapidary cabbing machines, gemstone preforming, and precision glass cold working. Featuring a precision-balanced composite hub and a densely electroplated 100-grit diamond cutting surface, this wheel bridges initial rough reduction and intermediate pre-polishing, allowing lapidaries and glass artisans to establish smooth contours while cleanly removing coarse grind marks.

Key Features

• High-Density 100 Grit Diamond Surface: Premium electroplated diamond abrasive delivers consistent material removal and smooth cutting action on hard agates, quartz, and jaspers.
• Precision-Balanced Hub Construction: Eliminates vibration and runout at standard machine speeds, protecting arbor bearings and ensuring uniform grinding contact.
• Rigid Flat Profile: True 1-1/2" flat grinding face maintains crisp edges, flat specimen surfaces, and accurate cabochon girdles.
• Standard 1" Arbor with Reducer Bushings: Includes precision reducer bushings to fit 3/4", 5/8", and 1/2" machine arbors seamlessly.

Applications

• Cabochon Shaping & Girdle Profiling: Refining rough cabochon profiles and defining uniform girdle lines on agate, jade, petrified wood, and beryl.
• Glass Cold Working & Beveling: Smoothing sawed edges, removing chips, and shaping art glass or crystal pieces.
• Mineral Specimen Prep: Pre-polishing flat faces and squaring edges on slabs and mineral specimens.

Technical Specifications

• Diameter: 6 inches (152 mm)
• Width: 1-1/2 inches (38 mm)
• Grit: 100 Grit (Intermediate Shaping)
• Arbor Size: 1 inch (includes 3/4", 5/8", 1/2" reducer bushings)
• Bond Type: Heavy-Duty Nickel Electroplated Diamond
• Recommended Operating Speed: 1400–1800 RPM

Operating Guidelines

• Always operate with continuous, generous water cooling to lubricate the wheel, suppress dust, and flush swarf.
• Use light to moderate hand contact; allow the sharp diamond particles to grind without forcing the workpiece.
• Rinse and dry the wheel after use to maintain abrasive cleanliness and long service life.
