Are the threads on core drills standardised and a universal fit on all arbo rs or are they manufacturer specific. I have an Erbaur arbor but cannot get the specific diam. drill but can get one from another source just wondered if I need to invest in another arbor and pilot drill?

I've got a Macrist ddm1 and the 1/2 BSP arbor that came with it has fitted every core I've tried.
And the various makes and models at work all fit each other.
Thanks Steve and Adam, I have just checked mine and it is 1/2" BSP so it should be OK to go ahead and get the core drill I require.
