Core drills
Cast Iron is not produced as a standard tube. Maatmetaal Rotterdam B.V. has 6 drilling machines and 4 lathes with which, among other things, we can drill and/or turn the core from a solid bar to almost any desired size.
If the size turns out to be too large, there is still the possibility to offer as permanent mould casting.
