Wrong drilling method (woodworking drill)
It is not enough to increase the rotation speed of the electric. The tip of the drill may be seized or chipped. </ span>
Maintain the proper rotation speed of the optimum drill.
In the case of a through hole, at the end, it assists after idling.
Drilling deeper than the groove length (effective length) will lead to damage to the drill, so drill with a drill that has a slight margin beyond the depth of the hole to be drilled. (We do not recommend the effective length of the last minute) </ span>
