Conmed 5.5mm, Sterling, Bur, Spherical, 20° Reduced Hood 55SPH-EL-RH
This is a 5.5 mm diameter spherical bur designed for arthroscopic resection and debridement. It features a 20° reduced-hood geometry to enhance access in constrained joint spaces. The large-hub “Sterling” connection allows compatibility with standard arthroscopic handpieces.
This spherical bur is engineered to provide efficient cartilage, osteophyte or bone debridement with a full spherical cutting surface for smooth, predictable removal. The 20° reduced hood design improves visibility and maneuverability in tight anatomical locations, such as the hip or shoulder joint. With the extended-length 19.0 cm design, it enables deeper joint reach while maintaining ergonomic handling. Its Sterling manufacturing ensures a sharp, consistent edge and reduces clogging for a more efficient surgical procedure.
