The High Speed Steel Ball Burs Size 22 (5.2mm) Round is a high-performance cutting tool designed for professional jewelers who require precision, control, and exceptional durability. Crafted from premium high-speed steel (HSS), this bur delivers maximum cutting efficiency and long-lasting sharpness, making it ideal for heavy-duty jewelry work and advanced metal shaping processes.
With its 5.2mm round cutting head, this bur offers a larger cutting surface perfect for creating deep, smooth cavities, broad shaping, hollowing, bevel refinement, and large stone-seat preparations. Its spherical geometry ensures controlled metal removal while maintaining power, balance, and stability at high rotational speeds. This makes it a superior choice for professional jewelers who need accuracy in larger-scale detailing and shaping tasks.
Equipped with spiral-cut precision flutes, the bur provides smooth material evacuation and minimizes heat buildup, allowing clean, consistent cutting on gold, silver, platinum, brass, copper, and other jewelry alloys. The standard 3/32" (2.35mm) shank ensures full compatibility with rotary handpieces, flex shafts, and micromotors used across professional jewelry workshops.
Engineered to maintain cutting integrity under demanding workloads, this HSS ball bur significantly reduces friction, tool wear, and the need for frequent replacements. Its performance and longevity make it an essential tool for bench jewelers who require top-level accuracy in large cavity formation, stone setting preparation, and advanced metal sculpting.
The High Speed Steel Ball Burs Size 22 (5.2mm) Round blends strength, efficiency, and precision to deliver industry-level results for demanding jewelry applications.
