Usage Note 2

After using it for a period of time, the sharpness of the drill bit may decrease. At this time, you only need to drill the drill bit back and forth on the grinding wheel a few times (it is recommended that the drill bit depth is 2mm and cannot drill through) to expose the diamond on the drill bit again. The drill bit becomes sharper and can continue to be used.

When the diamond part on the drill bit is used up, the drill bit cannot be used again.
