Thought just occurred to me, EMC will thread mill, right? Given the number of holes, you might consider popping for a Thriller made by Emuge. Properly programmed, it will drill, thread, and chamfer the hole. Emuge has details of how to program the thread milling, use that data in a subroutine. I'm not familiar with subroutine calls with repeats, but done properly, I think you could get away with a sub call for one row, a sub call repeating that row call in the other axis, and the subroutine itself. A potential job several years ago would have involved huge amounts of drilling and tapping 1/4-20 blind holes. Had the job come through I would have quickly gotten into a machining center. I contacted Emuge for some details on cycle time. Given a 10K spindle and proper coolant, an engineer told me to expect a cycle time of a few seconds per hole. You don't have that RPM or high volume coolant, but it should give you an idea. Of course, being mostly hobby, gotta weigh time vs money...
