Made in Mainland China.
Key Features
- Brazed Diamond Technology: Diamonds are brazed directly onto the wheel, creating a stronger, more stable bond than electroplated alternatives — resulting in higher efficiency and significantly longer working life.
- P60 Grit: Aggressive enough for rapid material removal on hard surfaces, while still delivering a clean, controlled edge finish.
- Dry & Wet Use: Flexible for use with or without water, adapting to your workflow and material requirements.
- Wide Material Compatibility: Ideal for marble, granite, quartz, ceramic, artificial stone, glass, and concrete — perfect for construction, renovation, and decorative finishing work.
- Universal Angle Grinder Fit: 20mm inner hole fits most standard angle grinders for quick, hassle-free attachment.

Frequently Asked Questions
Q: What materials can this 3-inch brazed diamond grinding disc cut or grind?
A: This brazed diamond abrasive disc is designed for hard materials including marble, granite, quartz, ceramics, porcelain, artificial stone, glass, and concrete. It is especially effective for edge grinding of marble or granite boards and surface flattening of concrete floors.
Q: What is the difference between a brazed diamond wheel and an electroplated diamond wheel?
A: Brazed diamond wheels use a high-temperature brazing process to bond diamond particles directly to the metal substrate, resulting in a much stronger and more secure bond. This means greater grinding efficiency, more diamond exposure for faster cutting, and a significantly longer service life compared to standard electroplated diamond wheels.
Q: Can I use this disc with water (wet grinding)?
A: Yes. This grinding disc is fully compatible with both dry and wet grinding methods. Using water during wet grinding can help reduce dust, manage heat, and extend the life of the disc — especially useful when working with delicate stone surfaces.
Q: What size angle grinder does this disc fit?
A: This disc has a 20mm inner arbor hole and a 75mm (3-inch) diameter, making it compatible with most standard angle grinders that accept a 3-inch wheel with a 20mm arbor. Always ensure your grinder's maximum RPM rating is compatible before use.
