🔥 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
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.
-
Q Does this diamond drill bit require water cooling during use?For sizes 5–12mm, no water is needed. These bits feature built-in high-quality cooling wax that melts during high-speed rotation to absorb heat automatically. Larger sizes may benefit from occasional water cooling for optimal performance on very dense materials.
-
Q What materials can this drill core bit be used on?This bit is suitable for tiles, ceramics, granite, marble, natural stone, and concrete walls. It is ideal for home decoration, construction engineering, and professional stone processing applications.
-
Q How does vacuum brazing technology improve the drill bit's lifespan?Vacuum brazing creates a strong metallurgical bond between the diamond particles and the steel body, far stronger than standard electroplating. This results in 3–5 times longer durability, reducing the need for frequent tool replacements and lowering overall cost.
-
Q What size range does this drill core bit set cover?The set covers a diameter range of 25mm to 68mm across 5 components, making it suitable for a wide variety of hole sizes required in different renovation and construction scenarios.
-
Q Will this bit cause chipping or cracking on delicate tiles or marble?The optimized diamond distribution and high exposure rate are specifically designed to minimize chipping and breakage. The excellent heat dissipation also prevents thermal damage to brittle materials, resulting in clean and smooth finished surfaces.
