The Busch® Burs Pearl Drills 0.9mm, ISO #090 – Pack of 6 are expertly designed for professional jewelers seeking precision and care when working with delicate materials such as pearls. Since 1905, Busch has been a global leader in manufacturing high-precision rotary tools, renowned for their exceptional durability, sharpness, and consistent quality that jewelers rely on for intricate and delicate work. These pearl drills feature a unique smooth flat head with a 0.9mm diameter, crafted from hardened steel for superior strength and longevity. The carefully engineered design ensures the creation of clean, soft-edged holes in pearls, minimizing the risk of chipping or cracking the fragile nacre. With a 4.2mm working head depth, these burs provide consistent, reliable results whether drilling fresh holes or enlarging existing ones. Compatible with various rotary tools—including pendant drills, micromotors, flex shafts, and pin vices—these burs allow jewelers to maintain full control and accuracy throughout their work. For optimal performance, pearls should be secured in a pearl vice or held gently between fingers wrapped in protective tape. Drilling under water or a damp environment is recommended to reduce friction, prevent overheating, and preserve the pearl’s natural luster.
Manufactured in Germany under rigorous quality standards, Busch® Burs Pearl Drills are prized for their longevity and precision. Their smooth finish and minimal vibration reduce user fatigue, making them essential tools in any jeweler’s toolkit. Whether crafting fine jewelry, repairing pearls, or performing delicate beadwork, these burs deliver the quality and precision demanded by professional artisans.
