1...it could be, but be very careful where the shavings go

2...you drill out 90% of the stud, there is just a thin circle left when you finish drilling.

3...No, there is not a hole all the way through, you have to be carefull not to drill too deep.

4...Pinning is putting a pin sideways through part of the casting of the head and through the stud so that it doesn't pull out
