ABSTRACT:
This disclosure relates to the construction and method of using synthetic diamond dies for drawing wire through a land or throat of a passage through the diamond die with the land or throat located midway between the opposite sides of the synthetic diamond and with approach passages located at opposite ends of the land so that the wire can be pulled through the die in either direction. This increases the useful life of the die before it becomes necessary to resize the die. The object of the invention is to reduce the cost of wire drawing through synthetic diamond dies.
