How to use glass hole opener:

The glass hole opener is installed on an ordinary electric hand drill (the electric drill can adjust the speed better), because this kind of hole opener does not have a central positioning drill bit, be careful when operating, first let the hole opener contact the glass slowly and diagonally Make a crescent socket on the side where the hole is not used, then position the drill bit and use this crescent socket to locate, so that the drilling operation can be completed smoothly. Note that the rotation speed should not be too fast when the hole is drilled, and it must be slow, as the saying goes Slow work produces fine work. In the process of drilling holes, water must be added to cool the hole opener. (It doesn't need much, but keep adding water). Dry drilling is strictly prohibited! (Dry drilling will cause high temperature friction, which will cause serious wear, affect the use effect, and shorten the service life of the hole opener!)
