5" 180 Grit Diamond Twin Spin Grinder Disk for Lapidary Grinding

The 5" 180 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 180-grit diamond particles, this versatile disc provides the ideal balance between material removal and surface smoothing on glass, tile, ceramics, and gemstones.

Key Features

• Dual Grinding Surfaces: Flat face for straight edge smoothing, leveling, and pre-finishing; radiused outer perimeter for contouring, beveling, and miter edge shaping.
• Medium 180-Grit Diamond Matrix: Uniform electroplated diamond layer smoothly transitions workpieces from rough cutting to fine finishing without chipping.
• 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: Medium edge finishing, precision beveling, and chip-free contouring on art glass panels, fused glass, and stained glass pieces.
• Tile & Ceramics: Smooth edge beveling, corner rounding, and transition grinding on porcelain, ceramic, and quarry tiles.
• Lapidary & Gemstones: Intermediate cabochon shaping, facet truing, and scratch reduction on agate, jasper, quartz, and jade.

Technical Specifications

• Diameter: 5 inches (125 mm)
• Grit: 180 Grit (Medium Pre-Finishing / General Shaping)

Operating Guidelines

• Continuous Water Coolant Required: Always operate with continuous water coolant to keep the diamond layer cool and flush grinding slurry.
• Apply light, even pressure across the wheel to prevent localized wear and preserve uniform surface geometry.
