What measures can be taken to prevent the bit from breaking?
I. to drill through, reduce the pressure. Slow down. Two. Drill the bit into a group
Especially in the hole is drilled, the drill tip has been exposed to the bottom surface, the feed speed must be slowed down, feed pressure must be reduced. In addition, if the drill is not fast, do not force to continue to use, so that the most likely to break the drill bit.
In drilling, the pressure must not be too great for the drilling hole to avoid breaking the bit.
