Donut Shape
Diamond Drill Bits
Diamond donut burs are specialized tools designed for carving and grinding ring or donut shapes into pre-drilled precious or non-precious stones or crystals. These burs feature a slightly concave shape with a raised central point, allowing for precise shaping of the desired ring or donut form.
They typically come with an 80# 240# and 320# and have a 6mm shank, making them compatible with various rotary tools. These burrs are available in different diameter sizes, ranging from 20mm to 50mm, providing options for different-sized rings or donuts.
Popular in lapidary work, these burrs are used with a wide variety of gemstones such as jade. Additionally, they are suitable for working on crystals, hard woods, bone, ceramics, glass, and stones due to their diamond-coated surface, which provides efficient grinding and shaping capabilities.
Their ability to precisely carve and grind specific shapes makes them valuable tools in jewelry making, lapidary crafts, and various artisanal endeavors where shaping stones or crystals into unique forms is required.

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.
