Mine are all coming in 2 medium flat rate boxes. 100 drills lol. So no tubes for me.Mine came in plastic cases. I marked each case (in really large characters on 2 sides) with the size of the MT drill. The tapered shank drills are well protected in these plastic cases.
I have the marked cases laying flat one layer deep on the shelf of a cart.
A block of wood seems like a good idea.
I like that idea and i know exactly what you are talking about. That would not take much to do either.My preference is to not use wood for storing cutting tools. Wood can absorb moisture which can lead to rusting. It also swells with moisture which can make tool removal more difficult There is expanded PVC material which is used for outdoor trim and railing which is easy to machine and dimensionally stable.
