Conmed 4.0mm, Large Hub, Sterling, Bur, Tapered H9121
H9121 is a 4.0 mm diameter tapered bur with a large-hub Sterling connection. It’s designed for arthroscopic or orthopedic shaver/bur handpieces. It’s used for controlled bone and cartilage shaping in joint surgeries.
This tapered bur is engineered for precision bone and cartilage resection, sculpting, and contouring during procedures such as acromioplasty or notchplasty. The tapered head geometry enables smooth shaping in tight or irregular spaces while minimizing risk to adjacent tissue. It is compatible with large-hub Sterling shaver systems for stable, high-speed rotation. The bur is sterile, single-use and designed to deliver consistent cutting performance and reliable torque transfer throughout surgical use.
