Drilling instructions

1. Glass has to lay down on a leveled , not too hard surface.

2. Glass should be never drilled completely from only one side, always from both

sides to  prevent glass from flaking.

3. To avoid overheating when drilling when splinters of glass in your eyes, you have

to use an oily liquid as a coolant and lubricant , for example Paraffin.

4. Drilling in glass is a slow operation.You have to work really carefully.

5. The revolutions when drilling should not exceed 100 rpm.

6. To fix hinges in a glass door you need really good drilled holes. For that 

we recommend shatter-proof glass.
