PRECAUTIONS

1. When drilling large diameter holes and the hardness of the material is high, water should be added to cool the drill bit. Water cooling while drilling can effectively prolong the service life of the drill bit.

2. During the use of the drill bit, the rotation speed should not be too fast. The drill bit must be drilled vertically with the workpiece to be processed. When the drill is stuck, do not force the drilling. It is better to take it out and continue drilling.
