I am happy that Bean Jewelries are received well and often asked what kind of tools I use to make jewelries with beans. So here I list up my suggestions.

Basic Tools for making bean jewelries
Micro drill bits to make holes on beans
Set of micro drills for workshop (0.8mm-1.0mm)
Your favorite beans! I especially like large beans to make a simple necklace.
Micro drill 0.8-1.0 mm up to the size of your parts and beans. A set of drill bits is a good option to save cost for a workshop.
If you make a lot of holes, it may make sense to invest on milling machine. I use the one from Proxxon, which has worked fine for more than 5 years.
