5" 360 Grit Diamond Twin Spin Grinder Disk for Lapidary Grinding

The 5" 360 Grit Diamond Twin Spin Grinder Disk is engineered specifically for Inland Twin Spin glass grinders and lapidary machines. Built on a precision-machined steel core with premium electroplated fine 360-grit diamond particles, this disc delivers smooth pre-polishing, delicate edge finishing, and micro-scratch elimination on glass, ceramics, porcelain, and gemstones.

Key Features

• Dual Grinding Surfaces: Flat face for straight edge smoothing, leveling, and pre-polishing; radiused outer perimeter for contouring, beveling, and fine edge shaping.
• Fine 360-Grit Diamond Matrix: Produces a satin finish that drastically reduces subsequent polishing stages while preventing edge chipping on delicate glass and minerals.
• Precision-Balanced Core: Solid metal base runs true and vibration-free on standard 5" Inland Twin Spin grinder arbors.
• Long-Lasting Bond: High-adhesion electroplated nickel matrix resists diamond stripping and premature wear.

Applications

• Art Glass & Stained Glass: Ultra-smooth edge refinement, delicate bevel finishing, and chip repair on stained glass, fused glass, and architectural glass.
• Tile & Ceramics: Fine edge truing, delicate corner smoothing, and micro-beveling on glazed tiles and precision technical ceramics.
• Lapidary & Gemstones: Final pre-polish smoothing and facet refinement on agate, jasper, quartz, turquoise, and jade cabochons.
