6" x 1-1/2" 600 Grit Sintered Diamond Grinding Wheel (Metal Bonded)

The 6" x 1-1/2" 600 Grit Sintered Diamond Grinding Wheel (Metal Bonded) is a premium fine-grit sintered wheel engineered for precision lapidary cabbing machines, fine gemstone smoothing, and optical glass cold working. Manufactured with a 5mm deep continuous sintered bronze metal matrix impregnated with monocrystalline micro-diamonds, this wheel provides an ultra-smooth satin surface on hard gemstones, eliminating residual scratches from 280/360-grit wheels and preparing stones directly for final pre-polish and cerium oxide/diamond compound polishing.

Key Features

• 5mm Continuous Sintered Diamond Depth: Micro-fine 600-grit diamond crystals are distributed completely through a solid 5mm bronze matrix layer, ensuring continuous performance across decades of heavy shop use.
• Flawless Satin Finishing: Delivers exceptional surface refinement on hard agates, jade, quartz, and petrified wood with zero risk of flaking, stripping, or diamond loss common to thin-plated wheels.
• True-Running Balanced Steel Hub: Precision-turned core runs without vibration or chatter at standard cabbing speeds (1400–1800 RPM), protecting arbor bearings and delivering uniform hand feel.
• Dressable Surface: Can be conditioned easily with an aluminum oxide dressing stick to maintain peak cutting speed and true rim flatness.
• Standard 1" Arbor with Reducer Bushings: Includes precision bushings to adapt to 3/4", 5/8", and 1/2" machine arbors seamlessly.

Applications

• Final Fine Smoothing & Pre-Polishing: Erasing all preliminary scratch patterns on agate, jasper, quartz, jade, sapphire, and hard mineral cabochons.
• Glass Cold Working & Bevel Finishing: Imparting a satin edge finish and pre-polishing optical glass, crystal art pieces, and fused glass components.
• Technical Ceramic & Hard Specimen Finishing: Micro-fine dimensional smoothing on alumina ceramics, silicon carbide, and mineral displays.

Operating Guidelines

• Always operate with continuous, generous flood water lubrication to keep temperatures low and prevent stone thermal shock.
• Apply light touch pressure; allow the fine sintered matrix to hone the surface smoothly without forcing the workpiece.
• Rinse and wipe clean after use; store dry to maintain wheel balance and matrix integrity.
