Thanks boys.

I have got a lot of suggestions, I am overwhelmed of the response,

everyone is correct, however not all are “workable? in this Project .

I ended up with a very short drill ?and a center drill from FIRST BROWN TOOLS LTD SHEFFIELD England . Both should be of a better quality.

They ?smell correct in original paper box. ?

The result is better than necessary. Only 600 holes have to be drilled.
