I despair.
You've done the Awareness course, you should now know that you do not drill it if you suspect it is any sort of asbestos.
As stated above, there are numerous different types, and some can be worked, with limitations, but you must be aware of what type it is, if you dont, then you dont get the drill out.
It isnt just you, the fibres will fall onto you, go through the house you are working on, blow off you onto anyoen near to you, then you'll be taking the fibres home with you, where the family will get the chance to breathe the dust.
Dont touch it.
