The High Speed Steel Ball Burs Size 23 (5.4mm) Round is a professional-grade cutting tool engineered for jewelers who demand power, precision, and long-lasting tool performance. Manufactured from premium high-speed steel (HSS), this large-diameter bur provides exceptional cutting strength and durability, making it ideal for shaping, hollowing, carving, and refining larger areas in metal.
The 5.4mm round head delivers clean, controlled material removal for applications requiring wider cuts and deeper cavities. Its precise spherical geometry ensures uniform shaping, perfect rounding, and smooth interior surfaces across a variety of jewelry metals. This bur is especially useful for carving recesses, forming domed profiles, opening wider holes, refining channel interiors, and creating smooth sculpted shapes in professional jewelry fabrication.
Engineered with precision spiral-cut flutes, the Size 23 HSS ball bur ensures efficient chip removal, reduced friction, and minimal heat buildup—even during extended cutting sessions. The standard 3/32" (2.35mm) shank guarantees compatibility with all professional-grade flex shafts, micromotors, and rotary handpieces.
Suitable for gold, silver, platinum, brass, copper, and other jewelry alloys, this bur maintains sharpness and performance even under demanding use. Its high-speed steel composition provides superior resistance to wear, extending tool life and ensuring consistent results for stone setters, wax carvers, metal sculptors, and fabrication experts.
The High Speed Steel Ball Burs Size 23 (5.4mm) Round is an essential tool for professionals seeking reliable cutting performance, smooth control, and precision shaping in larger-scale jewelry applications.
