The 7BA40 is a surgical dissecting / cutting tool in the Midas Rex Legend line, designed for precision bone work. The 4 mm ball‑shaped tip gives a rounded geometry that is less aggressive than sharp burs, which helps when sculpting curved surfaces, smoothing, debriding in tight anatomical areas, or performing delicate entry points without creating crests or sharp transitions. The fluted design allows efficient bone removal while also facilitating evacuation of bone chips and cooling fluid (if irrigation is used), reducing heat generation during use.

With a 7 cm shaft length, this tool balances access depth with maneuverability. It allows the surgeon to reach moderately deep or less accessible cavities, such as those in spinal, cranial, ENT or orthopedic surgery, while remaining controllable in hand and visible within the surgical field. The 4 mm head diameter provides a moderate volume of contact—a compromise between smaller heads (for fine detail) and larger ones (for bulk removal).

Because it is sterile and single‑use, the 7BA40 is intended to maintain consistent sharpness, avoid fatigue from repeated sterilization cycles, and minimize risk of cross‑contamination. The compatibility with the Legend system and various Small Bore attachments (straight and angled) ensures this tool can be swapped in and out efficiently, adapting to the needs of differing anatomies and surgical approaches. Its fluted ball tip style makes it a useful general‑purpose bur in the Legend line, especially when surgeons require smoother bone resection with less risk of cutting into surrounding soft tissues.
