Summary

Description
English: A "blowhole" casting defect in a commercial steel lathe face plate. A bubble of air became mixed into the molten iron, then froze with the metal into the plate, and was only exposed while machining the bolt slots. This part is still usable, although overtightening a bolt over the hole could crush part of the plate.
