During the drilling process, water must be continuously added. Remember not to open holes on the tempered glass. During the drilling process, because the center drill position is in a sealed state and cannot be cooled by water, the center positioning drill is easy to burn out. The center drill is removed and the hole is continued, thus avoiding the rapid wear of the center drill.

2. Select the processing material, do not drill holes in the tempered glass.
3. The appearance of the product will be slightly different. For example: the hole opener below 25mm is a hollow handle, and the hole opener above 28mm is a solid handle. This is designed according to different product specifications for the convenience of users, please rest assured to buy!
