Another of my weird questions - Counterbores and piloted D bits?

[R.G.]

Thanks for all the pointers. I'm once again stuck with needing to make tools to make tools that make the stuff I want.

I don't think anybody ever had that problem before... :roflmao: did they?

Real life has intervened and it'll be some time before I can get back to the shop. I'll post back when I get some results.
