Yangtzone Glass Cutting Disc 4.5 inch Diamond Blade – Ultra-Thin 5-Pack for Angle Grinders

Precision glass cutting with a purpose-built diamond blade

Yangtzone’s 4.5 inch glass cutting disc blends premium materials with thoughtful design to deliver reliable performance across glass, bottles, tile, jade, crystal, and beyond. This blade uses diamond high-manganese steel with brazed edges, delivering strong heat resistance and steady cutting action from start to finish. The ultra-thin profile minimizes edge chipping while maintaining robust cutting power, enabling cleaner edges with less dust and noise on the job.

Designed to work with most 4.5 inch angle grinders, it supports a 7/8 inch arbor and includes 4/5 inch bushing rings for flexible tool fitting. Whether you are refining a glass bottle project or trimming ceramic tile, the blade provides predictable control and dependable results in dry or wet cutting conditions.

Versatility, tips, and best practices

These discs are designed for flexibility: cut, bevel, or grind glass, wine bottles, jade, crystal, ceramics, and tile. They perform well in both dry and wet cutting scenarios, which can help manage heat and edge quality depending on your material and workflow.

For best results, maintain a steady pace, support the workpiece, and adjust speed to the material. When cutting glass, a light water mist can help control heat and dust, while consistent feeding pressure promotes smooth edges and better control.

Safety and care

Always wear safety glasses, gloves, a dust mask, and hearing protection. Inspect discs before use and stop if you notice edge chipping or vibration. Store in a dry place and clean after use to extend life.
