收藏: Sintered Diamond Bur

The Sintered Diamond Bur is a professional-grade lapidary diamond bur designed for grinding, carving, shaping, and engraving the hardest materials including gemstones, jade, quartz, agate, marble, granite, ceramics, and glass. Unlike standard plated burs that lose cutting power once the coating wears off, this diamond carving bur is fully sintered, meaning diamond grit runs throughout the entire head, exposing fresh layers of diamond as it wears down for maximum durability and consistent performance. Available in multiple shapes such as ball, bullet, cone, cylinder, and flame, and with common shank sizes (2.35mm, 3mm, and 6mm) to fit Dremel, Foredom, and air grinders, these diamond rotary burs deliver precise control for both rough shaping and fine detailing. Perfect as a gemstone grinding bur, glass engraving bur, or ceramic carving tool, the sintered design ensures a long lifespan, efficient cutting, and professional-quality finishes for lapidary artists, stone carvers, and glassworkers alike.
