3. Rinse under running water to rinse off the disinfectant.

With proper care and intensive use, the life of the bit is 6 months or more!

Note:  If you are using a nail drill with an Easy bit change system (pull-out & push-in type) such as MediPro or MediPower, we cannot guarantee that all of our bits will hold well in the handpieces and will not fly out at work. This is due to the fact that handpieces with automatic clamping mechanisms are very sensitive to the diameter of the shank, and if this size is not exactly 2.35 mm,  the bit may not hold well and may fall out during operation. In this case, we recommend that you use bits that are designed for your handpiece. At the same time, we guarantee that there will be no problems in all other devices with a collet clamp.
