6" x 1-1/2" 360 Grit Lapidary Diamond Hard Flat Grinding Wheel

The 6" x 1-1/2" 360 Grit Lapidary Diamond Hard Flat Grinding Wheel is a fine pre-polishing wheel engineered for 6-inch vertical cabbing units and bench grinding machines. Built with a solid precision-machined steel core electroplated with high-purity 360-grit monocrystalline diamonds, this hard wheel delivers delicate, vibration-free surface refinement. It systematically eliminates 220- and 280-grit scratches, imparting an ultra-smooth, uniform matte finish across agate, jasper, quartz, jade, ceramic, and art glass while preserving sharp corners and crisp flat planes.

Key Features

• Solid Steel Core Balance: Precision-turned rigid steel construction prevents deflection and runout, providing whisper-quiet rotation at 1400–1800 RPM and protecting machine bearings.
• Uniform Electroplated Diamond Coating: Dense 360-grit diamond coating bonded in tough nickel provides smooth cutting action, long working life, and zero wheel dressing required.
• Fine Pre-Polish Surface Refinement: Removes prior grinding lines effortlessly, establishing a flawless foundation that cuts down fine resin-wheel sanding stages.
• True-Flat Face Profile: Retains strict dimensional stability across the full 1-1/2" width, perfect for grinding crisp edges, flats, and precise 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

• Fine Cabochon Pre-Polishing: Pre-polishing cabochon domes and calibrating girdles on agate, jasper, jade, and quartz.
• Glass Cold Work Edge Refinement: Fine edge seaming, bevel smoothing, and finishing on art glass and fused glass pieces.
• Mineral Specimen Prep: Finishing flat display faces, quartz geodes, and petrified wood slabs.

Technical Specifications

Operating Guidelines

• Always use continuous water cooling to flush mineral slurry and keep work surfaces cool.
• Apply light, gentle hand pressure; let the diamond do the cutting to achieve the finest possible surface finish.
• Avoid concentrated corner point pressure to protect the rim edge diamonds.
