1. Is equipped with upper and lower drill bit., 2. Holes of different sizes can be achieved with bits of different diameters. - details see: https://www.machineto.com/glass-drilling-machine-10084490

Glass Drilling Machine (two drilling bits) is suitable for drilling hole for different glass thickness and drilling different diameter hole by equipping different drilling bits. The machine is good for batch processing.

1.Detailed description:

1.1) The Glass drilling machine is a cold processing machine which is easy to drill holes on sheets of glass and is equipped with upper and lower drilling bit.. An automatic cylinder drives the lower-drill bit while the upper bit is operated by manual. When the glass is put on the table, it is fixed pneumatically and the lower drilling bit will rise up automatically to drill from the bottom side of the glass. Then the upper drilling bit will drill the top side of the glass and then the hole is drilled through.

1.2) The cooling water runs inside the core drill so that the cooling effect is directly acted onto the glass without any loss.

1.3) The spindle design is sophisticated such that it is strong enough for 24 hours running a day. The rigid and anticorrosive spindle enables maintenance free.

1.4) Holes of different sizes can be achieved with bits of different diameters.

1.5) This machine works efficiently, it has low glass damage and is easy to operate.
