Has anyone ever used one of these? Got a chance to buy one cheap-ish about half of what they seem to be going for on ebay atm, wondered if they're good kit?
They are excellent bits of kit if you need to thread away from the workshop. I got mine probably 15 years ago when I was re-plumbing the 1/2" and 3/4" gas barrel for the driers in my launderettes (Mind you I still had to do the 2" BSP with a ratchet stock and much sweating )
Handy also as you can use them down a narrow trench. As has been said use a cordless drill in place of the handle.
Mine sits on the shelf and very rarely comes out to play these days - I think last time I did some 20 mm re-bar for my brother when his pagoda was disintegrating !
