5" 60 Grit Diamond Twin Spin Grinder Disk for Lapidary Grinding

The 5" 60 Grit Diamond Twin Spin Grinder Disk is specifically engineered for Inland Twin Spin glass grinders and lapidary machines. Built on a precision-machined steel core with premium electroplated coarse 60-grit diamond particles, this heavy-duty disc delivers rapid stock removal, fast glass edging, tile shaping, and lapidary pre-forming with true rotational balance and zero chatter.

Key Features

• Dual Grinding Surfaces: Flat face for straight edge smoothing, leveling, and stock removal; radiused outer perimeter for contouring, beveling, and miter edge shaping.
• Heavy-Duty Coarse Diamond Rim: 60-grit electroplated diamond layer provides aggressive, fast cutting action across dense, hard materials.
• 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: Fast edge trimming, gross shaping, and rough beveling on art glass panels, thick fused glass, and stained glass pieces.
• Tile & Ceramics: Rapid corner rounding, edge shaping, and thickness reduction on porcelain, ceramic, and quarry tiles.
• Lapidary & Gemstones: Rough contouring, slab pre-shaping, and aggressive stock removal on agate, jasper, quartz, and jade.
