Howard Hughes invented the tricon bit drill head, the fearsome looking three-section rotary drill that in magnified form, spearheaded Elliot Carver’s efforts to core out British ships in Tomorrow Never Dies.

Since Hughes, personal friend of Bond producer Cubby Broccoli, was the inspiration for Diamonds Are Forever’s uber-baron Willard Whyte, we thus have a fascinating link between the two films… and so it goes.
