Product Details

🔩 Product Overview

This is a Black Vacuum Brazed Diamond Drill Core Bit—a high-performance professional tool specially designed for precise drilling on tiles, marble, granite, and various other stone materials. It covers a full size range from 6mm to 130mm, comprehensively fitting diverse drilling scenarios such as home renovation, construction projects, and stone processing. Crafted with premium materials and advanced technology, this drill core bit stands out in durability, efficiency, and usability, becoming an ideal choice for both professionals and DIY enthusiasts.

⭐ 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 Extended Lifespan

    Adopting 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 Drilling Accuracy

    With 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 USE Versatile Application

    Widely 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 Does the Black Vacuum Brazed Diamond Drill Core Bit require water during drilling?
For sizes 5–12mm, no water is needed. These sizes feature built-in high-quality cooling wax that melts during high-speed rotation to absorb heat and cool the bit. For larger sizes, water cooling may be recommended depending on the application and material hardness.
Q What materials can this diamond drill core bit cut through?
This drill core bit is suitable for tiles, ceramics, granite, marble, natural stone, and concrete walls. It is designed for hard and brittle materials commonly used in home decoration, construction engineering, and stone processing.
Q How does vacuum brazing technology improve the lifespan of this drill bit?
Vacuum brazing technology creates a strong metallurgical bond between the diamond particles and the steel body. This makes the bond far more durable than standard electroplating, resulting in 3–5 times longer tool life and significantly reducing replacement frequency and overall costs.
Q What size range does this drill core bit cover?
The Black Vacuum Brazed Diamond Drill Core Bit is available in sizes ranging from 6mm to 130mm, making it suitable for a wide variety of drilling scenarios from small precision holes to larger openings required in construction projects.
