well its a hobby machine and I have bought used machines with dimples in the table. But I make it a point to fire anyone who drills into my milling tables. While your doing it intentionaly

most of the time its a careless accident, and I can do without careless accidents into my 30k to 150k machine tools.
Just out of curiousity is this a purpose build machine? becuase you can't take those holes back! ahhhhhhhhh the horror of it!
