I worked in a machining and manufacturing shop. I don't understand why a shop would tell you it would break their machine. We made products like this for customers frequently. It would seem to me this shop didn't want to do this for you. Setup and programming the machine takes a lot of time and then there are tool costs, power costs, coolant and labor costs. The problem is expense. The reality is your little job would either cost you immensely more than it is worth or the shop would lose money from not making a larger volume of profitable parts and from downtime to help you with yours.If you have a drill press or know someone that does. You can easily drill these holes yourself.
