UNF HSS Dies and Dienuts. Unified National Fine Dies and Dienuts to BS 949 , ISO 529.

Split circular Dies are stocked as standard. General purpose dies for use on most common materials. The chamfer is ground, with lapped threads and cut thread consistently to size.

Dies are available in the solid version on request and also with a spiral entry. The spiral entry causes a peeling cut with swarf being forced ahead of the die - use recommended for use in attachments or machines.

If your size requirement is not listed please enquire all Dies and Die nuts can be sourced.
