The CORI Handpiece can power up to how many RPM?

• A. 30,000 RPM
• B. 60,000 RPM
• C. 90,000 RPM
• D. 120,000 RPM

Answer: (B)

The speed a handpiece can reach is tied to how it balances cutting power with heat and wear on the instrument. The CORI Handpiece is designed to deliver up to 60,000 RPM. This ceiling gives enough cutting speed for efficient preparation while keeping heat generation and bearing wear under control, especially when used with proper cooling water. Speeds higher than that would demand more cooling and stronger heat management, and could push the system toward overheating or faster wear. Slower speeds, like 30,000 RPM, would reduce cutting efficiency, making procedures slower and tougher on hard tissues. So 60,000 RPM is the right, practical limit for this device.
