Circular Cutting Punch, 3.5mm Diameter, Upturned, Working Length 160mm

This upturned circular cutting punch produces a 3.5mm diameter aperture in a single motion for tympanic membrane perforation creation or round window niche work during otologic and skull base procedures. The upturned geometry maintains visualization during the cutting stroke, and the 160mm working length reaches into the mastoid cavity. Stainless steel provides durable cutting performance.

Features & Benefits

• 3.5mm diameter circular aperture for tympanic and osseous work
• Upturned geometry preserves intraoperative visualization
• 160mm working length reaches mastoid depths
• Single‑motion design improves procedural efficiency
