Usage: It can be used for opening glass. It is suitable for hand drill/bench drill (do not drill tempered glass).

Warm Tip:

Water must be added in the process of drilling. Good cooling can prolong the service life of the drill. Do not drill without water, otherwise it will easily cause damage to the drill.

Since there is no central drill for the glass opener, it should contact the glass slowly at an angle of 45 degrees. After a month\'s alveolar traces have been opened, it can play a positioning role, and then set the positive electric drill to open the hole vertically.
