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 Lifespan 3–5× Durability

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

It is 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 What sizes are available for the Black Vacuum Brazed Diamond Drill Core Bit?

The drill core bit is available in a full size range from 6mm to 130mm, making it suitable for a wide variety of hole sizes required in home renovation, construction projects, and professional 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. Larger sizes may require standard cooling methods depending on the application and material.

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. Unlike standard electroplated bits where diamonds are surface-bonded, this fusion ensures the diamonds are held firmly in place, resulting in 3–5 times longer durability and significantly reduced tool replacement frequency.

Q What materials can this diamond drill core bit cut through?

This drill core bit is designed to work on a broad range of hard materials, including ceramic tiles, marble, granite, natural stone, and concrete walls. It is ideal for both decorative and structural drilling tasks in home decoration and construction engineering.

Q Will this drill bit cause chipping or cracking on delicate tile surfaces?

No. The optimized diamond distribution and high exposure rate of the drill bit minimize chipping and breakage. Its excellent heat dissipation also prevents thermal damage to brittle materials, resulting in smoother, cleaner hole edges on tiles and stone surfaces.

Q What packaging set options are available for purchase?

The drill core bits are available in multiple set options to suit different project needs: 6pcs, 8pcs, 9pcs, 10pcs, and 12pcs sets. Each set comes in a dedicated box for easy storage and transport, making them convenient for both professionals and DIY users.
