What are these? Die half’s?

A chap at a company i go to gave me a box of these

What do i need to hold these…I’m presuming they are die nuts that go in a special holder?

They are similar [but not identical] to some I had in a long holder that took several sizes at once.

Big thumbscrew at the end to adjust the one currently in use.

Sorry, no photo because I don’t have it now.

They look like American style dies. Google "little giant" taps and dies for an example

Hi Ian, these types have been asked about a while back, and are similar to the ones shown below.

Regards Nick.

Complete adjustability with the added ease of restoring damaged threads.

The half dies were also made by Warrior. I posted this picture before in another thread.

This shows the holder and securing piece as well as 4 different dies with their respective sized guides

Hi MichaelG, well I do like coconut, had just a couple of weeks ago. A Previous Thread is the one that both Derek Lane and myself, posted other makes of these types.

Regards Nick.

The ones i was given today are a set of metric pairs 5,6,7,8,9,11and 12mm. No 10mm sadly

theres a date on them 1944 with an arrow…is that a MOD mark?

i wonder how many metric threads were needed in the post war years and I’ve never needed 7,9 and 11mm threads

the die holder i pictured i have bought on eBay looks to be the same brand “easterbrook” so hopefully it will work
