I have a sheet of styroglass, which I assume by the name to be a clear polystyrene.
I want to drill some M4 holes into it, which are about 2.5cm separated from each other.
However, I only have drillbits for wood and stone here. Will I be able to dill the holes with these or do I risk to crack the material? Should I go for another type of dillbit or just use strong glue?
