How to use glass perforator:

glass perforator is installed on ordinary electric hand drill (electric drill can speed up better), because this hole opener does not have a center positioning drill, be careful when operating, first, let the hole opener open a Crescent groove on the side where the hole is not used to touch the glass at a slow speed, then put the drill bit and use this Crescent groove to locate it, so that the opening operation can be successfully completed, note that the speed should not be too fast when opening the hole, and it must be slow. As the saying goes, slow work makes fine work. During the opening process, water must be added to cool the hole opener. If the hole opener Burns, don't contact us!
