6" x 1-1/2" Sintered Diamond Grinding Wheel – Metal Bonded for Lapidary & Glass

The 6" x 1-1/2" Sintered Diamond Grinding Wheel (Metal Bonded) is a heavy-duty, commercial-grade grinding and preforming wheel built for lapidary cabbing machines, gemstone preforming, and precision glass cold working. Engineered with a full 5mm deep sintered diamond-impregnated bronze-metal matrix, this wheel provides continuous self-sharpening abrasive exposure, exceptional wheel longevity, and fast, chip-free material removal on the hardest mineral and glass workpieces.

Key Features

• Full 5mm Sintered Diamond Rim: Premium diamond abrasive impregnated completely through a 5mm bronze-metal layer, outlasting electroplated wheels up to 50 to 100 times.
• Continuous Self-Sharpening Action: As the bronze bond wears during wet grinding, new sharp diamond points are continuously exposed to ensure steady cutting performance.
• Aggressive Stock Removal & True Cabbing Precision: Ideal for rapid gemstone preforming, slab edge beveling, and heavy glass waste reduction without surface glazing.
• Precision-Balanced Solid Steel Core: Perfectly balanced machined steel hub runs completely vibration-free, protecting machine bearings and ensuring precise hand control.
• Standard 1" Arbor with Precision Reducer Bushings: Includes precision bushings to adapt seamlessly to 3/4", 5/8", and 1/2" standard lapidary arbors.

Applications

• Hard Mineral & Gemstone Preforming: High-speed rough shaping of agate, jasper, quartz, sapphire, corundum, beryl, jadeite, and petrified wood.
• Glass Cold Working & Beveling: Edge grinding, facet roughing, and bulk stock removal on art glass, thick crystal, and optical materials.
• Technical Ceramics & Refractories: Precise shaping and dimensional grinding of alumina, silicon carbide, and technical ceramic components.

Technical Specifications

• Diameter: 6 inches (152 mm)
• Width: 1-1/2 inches (38 mm)
• Diamond Rim Depth: 5 mm
• Arbor Size: 1 inch (includes 3/4", 5/8", 1/2" reducer bushings)
• Bond Type: Sintered Bronze / Metal Bond Matrix
• Available Grits: 60, 80, 100, 180, 220, 360, 600 Grit
• Recommended Operating Speed: 1400–1800 RPM

Operating Guidelines & Dressing

• Always operate with continuous, generous flood water coolant to lubricate the wheel, suppress dust, and flush metal swarf.
• Apply light to moderate, consistent hand pressure; excessive force will not increase cutting speed and may cause premature matrix wear.
• Periodic dressing with an aluminum oxide dressing stick (or silicon carbide stone) easily re-opens the matrix if the wheel becomes glazed or loaded with rock sediment.
