This robust High Speed Steel Cylinder Bur #34 (11mm) with a 3/32" shank is manufactured from premium M2 High Speed Steel, ensuring exceptional durability and performance for demanding metalworking, jewelry making, and wax carving projects. The precisely engineered spiral-cut flutes provide efficient material removal, maintain a sharp cutting edge, and minimize chip loading, offering a significantly longer lifespan compared to burs made from tungsten, vanadium, or carbon steel.

This versatile 11mm cylinder bur functions like a miniature rotary file, enabling rapid material removal and precise shaping of various materials. Its larger diameter is particularly well-suited for enlarging ring shanks, creating smooth inner surfaces, and refining larger details on metal and wax models. The industry-standard 3/32" (2.35mm) shank ensures compatibility with the majority of flex shaft handpieces, rotary tools, and micro motors commonly used by jewelers, metalworkers, and hobbyists.
