• Safe design – minimizes the risk of cutting or irritating the skin.
• High durability – diamond coating built for long-lasting use.
• Work comfort – stable performance even at high speeds up to 40,000 RPM.

2. Set the speed up to 40,000 RPM.
3. Work using light, controlled motions with minimal pressure.
4. Do not keep the bit in one spot to avoid heat build-up.

Disinfection & sterilization
