Instructions:
The glass hole opener can be installed on professional drilling machines such as ordinary hand drills or bench drills. Since this kind of hole opener does not have a central positioning drill bit, During operation, first tilt the hole opener at 45 degrees , slow down the speed of the electric drill, and slowly touch the side of the glass without a hole to create a crescent socket.( The crescent socket can play a positioning role) , and then vertically drill the electric drill, so that the hole drilling operation can be completed smoothly. Note that the rotation speed cannot be too fast when drilling the hole, it must be slow, especially when starting to drill and when it is about to be drilled through. As the saying goes, slow work makes fine work. During the hole opening process, water must be added continuously to cool the hole opener. .
