Key Advantages
-
💧 Dry Drilling (No Water Needed)The 5–12mm sizes are equipped with built-in high-quality cooling wax. During high-speed rotation, the wax melts to effectively absorb heat, eliminating the need for water cooling. This design simplifies operation, avoids water stains on workpieces and surrounding areas, and makes drilling in narrow spaces or indoor environments more convenient and clean.
-
⚙️ 3X Longer LifespanAdopting advanced vacuum brazing technology, the diamond particles are firmly fused with the steel body, forming a strong metallurgical bond. This ensures 3–5 times longer durability than standard electroplated drill bits, greatly reducing tool replacement frequency and use cost.
-
🎯 Precise DrillingWith optimized diamond distribution and high exposure rate, the drill bit achieves fast drilling speed while minimizing chipping and breakage of workpieces. Its excellent heat dissipation performance prevents thermal damage to brittle materials, ensuring smoother and flatter finished surfaces.
-
🏗️ Wide ApplicationWidely suitable for opening holes in tiles, ceramics, granite, marble, natural stone, concrete walls, and other hard materials, meeting various drilling needs in home decoration, construction engineering, and stone processing fields.

Frequently Asked Questions
Q What materials can the Black Vacuum Brazed Diamond Drill Core Bit drill through?
This drill core bit is suitable for tiles, ceramics, granite, marble, natural stone, concrete walls, and other hard materials. It is designed to handle a wide range of hard surfaces commonly found in home decoration, construction engineering, and stone processing applications.
Q Do I need water cooling when using this drill bit?
For sizes between 5mm and 12mm, no water cooling is required. These sizes feature built-in high-quality cooling wax that melts during high-speed rotation to absorb heat effectively. For larger sizes, we recommend checking the product specifications or using water cooling as needed.
Q How much longer does this drill bit last compared to standard electroplated bits?
Thanks to advanced vacuum brazing technology, the diamond particles form a strong metallurgical bond with the steel body. This results in 3 to 5 times longer lifespan compared to standard electroplated drill bits, significantly reducing replacement frequency and overall tool costs.
Q What size range does this drill core bit cover?
The Black Vacuum Brazed Diamond Drill Core Bit covers a full size range from 6mm to 130mm, making it suitable for a wide variety of drilling scenarios from small precise holes to larger openings required in construction and stone processing.
Q Will this drill bit cause chipping or cracking on delicate surfaces like marble or tiles?
No. The optimized diamond distribution and high exposure rate allow for fast, precise drilling while minimizing chipping and breakage. The excellent heat dissipation also prevents thermal damage to brittle materials, ensuring smooth and flat finished surfaces.
Q What package set options are available for this drill core bit?
This drill core bit is available in multiple set configurations to suit different needs: 6pcs, 8pcs, 9pcs, 10pcs, and 12pcs sets. Each set comes packaged in a dedicated box for easy storage and transport.
