Whether you’re a professional jeweler or a dedicated hobbyist, these burs excel in engraving, deburring, drilling, and surface texturing on soft and hard metals such as gold, silver, platinum, brass, and more.
With an approximate length of 1-3/4" (44.5 mm) and a 3/32" (2.35 mm) shank, they are fully compatible with standard rotary tools, including flex shafts, micromotors, and Dremel-style tools. The consistent shank diameter ensures a secure fit for optimal control and precision during use.
To achieve maximum performance and extend tool life, it is highly recommended to use a quality lubricant such as Lube-Stik, which reduces friction, prevents overheating, and enhances cutting efficiency.
Each pack includes 6 meticulously crafted burs, made in Germany—renowned for engineering excellence and superior wear resistance. These burs are designed to maintain their edge longer, offering excellent value and professional-grade durability for all your metalworking projects.
