6" x 1-1/2" Diamond Steel Hub Textured Grinding Wheel for Lapidary & Gemstone Shaping

The 6" x 1-1/2" Diamond Steel Hub Textured Grinding Wheel is a precision heavy-duty lapidary grinding wheel built for maximum rigidity, vibration-free rotation, and aggressive stock removal across gemstones, hard minerals, and cold glass. Featuring a solid, precision-machined heavy steel hub plated with an advanced cross-hatch textured diamond matrix, this 6-inch wheel channels coolant efficiently across the contact zone, dissipating frictional heat and preventing surface chipping during demanding cabochon shaping and pre-forming.

Key Features

• Solid Machined Steel Core: Heavy-duty steel body ensures zero flex, exceptional balance, and true running without arbor deflection even under heavy grinding pressure.
• Cross-Hatch Textured Diamond Matrix: Patterned diamond channels continuously evacuate stone swarf and coolant slurry, preventing wheel loading and maintaining razor-sharp cutting speed.
• High-Concentration Monocrystalline Diamond: Premium electroplated diamond coating guarantees aggressive material removal and prolonged wheel service life.
• Universal 1" Arbor with Bushings: Precision 1-inch center bore includes reducer bushings to fit 3/4", 5/8", and 1/2" machine shafts.
• Full Progressive Grit Progression: Available from aggressive 60 grit for fast rough pre-forming down to 600 grit for smooth, scratch-free pre-polish finishing.

Applications

• Lapidary Cabbing & Pre-Forming: Fast stock removal, dome shaping, and contouring on agate, jasper, quartz, jade, petrified wood, and tough lapidary stones.
• Glass Cold Working: Grinding punties, beveling bottle edges, smoothing fused glass edges, and shaping sculptural glass pieces.
• Ceramic & Porcelain Fabrication: Leveling bottom rims, smoothing pottery edges, and correcting technical ceramic tile profiles.

Technical Specifications

Operating Guidelines

• Always operate with continuous water coolant to keep the workpiece cool and flush swarf out of the textured channels.
• Apply light to moderate contact pressure; let the rigid steel core and sharp diamond texture cut naturally.
• Rinse thoroughly after each grinding session and dry completely before storage to protect the steel body and diamond plating.
