1. The Horizontal Glass Drilling Machine is suitable for drilling hole for different glass thickness and drilling different diameter hole by equipping with different drilling bits. The machine is good for batch processing. 2. Two drilling spindles, one at the lower side and another upper side. When the glass is put on the table, it is fixed pneumatically and the lower spindle will rise up automatically to drill from the bottom side while the upper bit is operated by manual. 3. The cooling water runs inside the core drill so that the cooling effect is directly acted onto the glass without any loss. Holes of different sizes can be achieved with bits of different diameters.
