Sintered Diamond Core Drills

13mm

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.

FAQ

Q: How do you use a diamond pad?

A diamond hand pad is a handheld abrasive tool with a flexible surface coated with diamond particles. It is used for grinding, smoothing, and polishing various materials, including stone, concrete, glass, and metal.

Q: How do I choose the right grit size for my project?

Select the grit size based on the initial condition of your workpiece and the desired level of surface finish. Coarse grits are suitable for rough grinding, while finer grits are used for smoothing and polishing.

Q: What safety precautions should I take when using diamond hand pads?

Wear safety goggles, a dust mask, and gloves to protect yourself from dust and debris. Additionally, work in a well-ventilated area or wear a respirator if working with fine dust particles.

Q: How do I maintain and clean my diamond hand pad?

After use, rinse the diamond hand pad with clean water to remove debris and residues. Gently pat it dry or allow it to air dry. Proper maintenance can prolong the pad's lifespan.

Q: What are some common applications for diamond hand pads?

Wear safety goggles, a dust mask, and gloves to protect yourself from dust and debris. Additionally, work in a well-ventilated area or wear a respirator if working with fine dust particles.

Q: What are the common grit sizes for diamond hand pads?

Diamond hand pads come in a range of grit sizes, from coarse (e.g., 50 grit) to fine (e.g., 3000 grit). The choice of grit depends on the specific task, with coarser grits used for material removal and finer grits for polishing.

Q: Do I need to use water or lubricant with a diamond hand pad?

Yes, using water or a specific lubricant is often necessary. It helps keep the surface cool, prevents overheating, and improves the effectiveness of the diamond particles in grinding and polishing. Some materials require dry grinding, so it's essential to check the manufacturer's recommendations.

Q: Can I use a diamond hand pad for dry grinding and wet grinding?

The suitability of a diamond hand pad for dry or wet grinding depends on the material and the pad itself. Some diamond hand pads are designed for wet use, while others are suitable for dry grinding. Check the manufacturer's specifications for guidance.

Q: Can diamond hand pads be used on curved or irregular surfaces?

Yes, diamond hand pads are versatile and can be used on flat, curved, or irregular surfaces. Their flexibility allows for contouring and shaping of various workpieces.

Q: Can I achieve a high-polish finish with a diamond hand pad?

Yes, with the right technique and progression through finer grits, you can achieve a high-polish finish on various materials using diamond hand pads. The finest grits are typically used for the polishing stage.
