Diamond Coated Grinding Bit
Precision Diamond-Coated Rotary Burrs
Upgrade your rotary tool setup with these high-performance grinding bits. Designed for hardness and durability, they deliver sharp, consistent cuts on tough materials.
Forged with Real Diamond
These bits are crafted using premium diamond particles embedded directly into the metal core. This ensures extreme hardness that standard steel burrs simply cannot match. The result is a tool that stays sharp longer and grinds through hard surfaces with ease.
Titanium Plating for Long Life
The golden finish isn't just for looksâit's a titanium plating layer designed to resist wear and corrosion. Combined with evenly distributed abrasive particles, you get smooth, predictable grinding action without the bit deforming under pressure.
Built for Heavy-Duty Grinding
Whether you are deburring metal edges, shaping stone, or refining ceramic components, these cylindrical bits provide the stability and cutting power required for professional results. They handle high speeds effectively while maintaining their structural integrity.
Fine Detail Work
The slim profile allows for precise access into corners and detailed areas. Ideal for jewelry making, model building, and intricate DIY repairs where control is just as important as power.
Select Your Size
All variations share a standard 3.0mm shank, ensuring compatibility with most common rotary tools (such as Dremel). Choose the diameter that best fits your specific project needs.

| 4.0 mm | 3.0 mm | 20 mm | 45 mm | 3.0 g |
| 4.8 mm | 3.0 mm | 20 mm | 45 mm | 4.0 g |
| 5.5 mm | 3.0 mm | 20 mm | 45 mm | 4.9 g |
Frequently Asked Questions
Yes, these bits feature a standard 3.0mm shank. They are compatible with most major rotary tool brands and chucks that accept 3mm accessories.
The diamond coating makes them suitable for very hard materials including glass, ceramics, stone, marble, granite, and hardened metals.
The diameter refers to the width of the grinding surface. A smaller diameter (4.0mm) offers more precision for tight spots, while a larger diameter (5.5mm) removes material faster on broader surfaces.
While not strictly mandatory for short bursts, we highly recommend using water or coolant when grinding heat-sensitive materials like glass or stone to prolong the life of the bit and prevent cracking.
