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.

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 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

    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 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.
