5" Diamond Twin Spin Grinder Disc for Glass, Tile & Stone Shaping

The 5" Diamond Twin Spin Grinder Disc is engineered specifically for Inland Twin Spin glass grinders and lapidary equipment. Featuring a precision-machined steel body coated with commercial-grade electroplated diamond abrasive across both its top flat face and outer perimeter, this versatile disc provides aggressive stock removal, straight edge beveling, and contour shaping on glass, ceramics, and stone.

Key Features

• Dual Working Surfaces: Flat top face designed for straight edge beveling, thickness thinning, and surface leveling; radiused outer perimeter shaped for curved edge contouring and miter shaping.
• Multi-Grit Availability: Available in 60 Grit (coarse stock removal), 180 Grit (medium shaping), and 360 Grit (fine pre-polishing).
• Precision-Balanced Hub: Perfectly balanced solid metal construction eliminates vibration and chatter on standard 5" Inland Twin Spin arbors.
• High-Durability Electroplated Bond: Premium diamond matrix resists stripping and premature edge rounding under demanding use.

Applications

• Art Glass & Stained Glass: Fast edge trimming, custom contour beveling, and chip-free edge refinement on stained glass and thick fused glass panels.
• Tile & Ceramics: Clean edge truing, miter corner grinding, and leveling on porcelain, ceramic, and stone tiles.
• Lapidary & Gemstones: Slab pre-forming, cabochon shaping, and pre-polish scratch smoothing on agate, jasper, quartz, and jade.
