The enormous and prestigious B6 boring machine that was used to dig the passageway has been innovatively recycled and put to new uses by Kents leading metal advocate Reclamet.
But while pieces of the 560 tonne machine responsible for one of the greatest modern engineering feats are spread all around society, its historical significance didnt extend to recycling the B6 in its entirety.
Reclamet chief executive Tony Wilkinson is offering some of the teeth which cut the channel tunnel to interested parties in a move designed to raise money for the Cancer Care Appeal.
There are now 215 teeth left from a machine that the company bought for nearly £40,000 after a fiercely fought E-bay auction battle.
Details of how to obtain one of the mounted, individually numbered, certificated and authenticated pieces of history are available at www.reclamet.co.uk.
