I'm after a 152mm (Or thereabouts) core bit.

It needs to do two holes through soft brick/Breeze.

Hire shops want ?40+VAT per day plus a "wear charge".

Anyone seen cheap ones for sale anywhere? It doesn't need to be too
good as it's only going to be used for two holes.

If you're feeling especially cheap, and especially for only two holes,
have you considered chain drilling?
