Creating a matching thread using a mould

I have 2 separate part files.

One has male thread and the other one does not have any thread yet.

I would like to insert the one with male thread into the part without thread yet, so that i can use it to 'remove material' from the part to creating a matching female thread.

How do i do it?

Thanks heaps guys i really appreciate it. I'm just teaching myself to use Solidworks now as I was taught a different program and am struggling to transfer my knowledge.

Cheers,

Joe
