Ferrous Forgings

Trepanning

Trepanning is the process whereby a circular cutting tool is used to core out hollow sections as required. Ferrous Forgings do vertical trepan boring of holes in sizes of 4.5 inches (115mm) through to 21 inches (530mm) diameter over a length of 30 inches (750mm).  This service is extremely useful when you are trying to source a heavy wall hollow bar. Using this methodology Ferrous Forgings forge a bar to the desired diameter and then trepan the most suitable sized hole, leaving you with either a thin wall or heavy thick wall thickness in any material you require.
