Hello, We would like to know: What type of drill should we use (drills, corers, helical drills) for sampling operations?

Solved by Pierre-Yves Huet

Hello,
I'm not sure I fully understand your need, but know that in general, when you design your part and subcontract the manufacturing to a machinist, you don't need to select the tool yourself, simply specify the type of hole (drilling, boring, tapping), and indicate on your plans the associated dimensions and tolerances. For example, for a simple drilling, you can select the drilling option in your CAD software, and the nominal diameter will be the drilling diameter. If greater precision than the general tolerances is required, it is recommended to indicate the tolerance on the diameter, for example H7 or H8, the most common choices for bores or simple drillings.
I hope I have been able to help you. Don't hesitate to consult this article on the Xometry pro platform: https://xometry.pro/fr/guides/livre-blanc-types-trous-ingenierie/
Good luck with your project!
