we priced a tap and die set from Atul in our last order - almost 300 bucks -never mind, ordered instead a few "boxes" of nuts and bolts for a few bucks. Nice to have extras.
You try finding 2" or 2-1/2" BSP taps and dies!
£500 for a 2" BSP die
We've got all the sizes from 1/8" BSP up to 2", the 2-1/2" is pretty rare on the Listers etc., but the 2" is CS exhaust pipe size.
A few years back these were being thrown away as engineering companies went bust, we bought as much as we could afford at the time, and now find them VERY useful!
The other thing to remember is that a 2" tap is almost impossible to use for tapping a hole, it's only really usable (by hand) for cleaning threads up, which of course if what we use them for.
