The kit includes three discs plus bushings to fit a range of arbors, making setup straightforward for diverse projects.

Why this disc stands out

Crafted from diamond-coated high manganese steel and upgraded with advanced brazing technology, the blade is built for speed and dependable edge retention. At 1 mm thickness, the blade creates a narrow kerf that helps preserve the original surface while you work, reducing the chance of accidental chipping on delicate pieces.

• Material & tech: diamond-coated, high manganese steel with upgraded brazing for durability and faster cutting
• Ultra-thin & precise: 1 mm thickness to minimize kerf and protect surface integrity
• Multipurpose: designed for cutting, grinding, and chamfering on glass, ceramics, tiles, jade, crystal, wine bottles, and more
• Packaging: includes 3 discs and 3 bushing rings (7/8" to 4/5") for flexible arbor compatibility

Practical uses

Whether you’re refashioning glassware, polishing tile edges, or preparing decorative pieces from bottles or crystal, this disc helps you achieve cleaner edges with greater control. The kit’s versatility supports a range of crafting and renovation tasks without swapping tools mid-project.
