Tips:
When drilling, the drill bit should be drilled reciprocally, not all the way into. The reciprocating drilling can bring the debris out to avoid blocking the hole. When it is about to be drilled through, it should be played on the other side, not once, to avoid the edge of the drilling collapse.
