Experience superior drilling performance with our Sintered Diamond Core Drills, engineered with a specialized metal bond for unmatched strength and reliability. These core drills are designed to withstand the rigors of demanding drilling tasks, making them the preferred choice for professionals in the construction, manufacturing, and gemstone industries.

Sintered Diamond Core Drills made with our exclusive metal bond developed for high strength and longevity，metal bond diamond core drills are the finest core drills manufactured in the world. Diamonds held in a metal matrix bond for core drilling glass, alumina quartz, ruby yag, silicon and other hard abrasive non-metallic ceramics.Sintered diamond drill bits are heavy-duty bits designed for long life.  Generally, sintered bits will have a long life of 20 to 30 or more times the life of a bonded diamond drill bit, if used properly.  The heavy-duty design provides long life when drilling in very hard materials such as porcelain tile, granite and hard stones.  However, there are some disadvantages.  Sintered core bits are much more expensive than nickel bonded diamond bits and the thick heavy-duty tip causes them to drill more slowly than thin-wall bonded diamond drill bit.

1. High Strength and Longevity: The exclusive metal bond used in these Core Drills is formulated to provide exceptional strength and durability. This makes them ideal for challenging applications where other drill bits might wear out quickly.

2. Long Life: Sintered diamond Core Drills are known for their extended lifespan. When used correctly, they can last 20 to 30 times longer than bonded diamond drill bits. This longevity can make them a cost-effective choice in the long run, especially for professionals and industries that require frequent core drilling in hard materials.

3. Suitable for Hard Materials: These Core Drills are specifically designed for drilling through extremely hard materials, including porcelain tile, granite, and hard stones. Their heavy-duty construction allows them to withstand the rigors of drilling in such challenging materials without premature wear.

Despite their advantages, there are a few drawbacks to sintered diamond core drills:

1. Higher Cost: Sintered Core Drills are generally more expensive than nickel-bonded diamond bits. This higher cost is primarily due to the advanced manufacturing processes and high-quality materials used in their construction.

2. Slower Drilling : The thick, heavy-duty tip of sintered Core Drills  can result in slower drilling speeds compared to thin-wall bonded diamond drill bit. The slower drilling pace is a trade-off for the durability and longevity offered by Sintered Core Drills .
