Drilling with a hand drill is a nightmare in situ and honestly going down the drilling route that will leave you with your sanity would require it to be done with a bench drill of sorts and removing the strut. The point about replacing it can be an issue if its stuck fast or damage has occurred in the frustration of trying to remove the bolt - 1st hand experience as have sold them for this reason.
There is a special VAG tool for doing these bolts. The other workshop tool out there is like wrapping a flexible kettle element around the top of the hub, which heats it to huge temperature and expands the outer casing and breaks the bond. I have not used one or seen it in action but have heard they are effective from one source, obviously same idea as heat which is the 1st thing to try imo.
