Adjustable Boring Bar

[jamesgates1000]

Hi does anyone know where i could get a reasonably priced adjustable boring bar, i need to open out a 22mm hole to 25mm with an accuracy of 0.01?
Alternatively does anyone in south dorset or bristol have one i could borrow?

Search for Boring Head.
There's a good few options listed on ebay, and I just noticed Arc Euro Trade have a new range of various sizes.

Final accuracy will be down to the operator far more than the quality of boring head used.

I'm assuming this is for a milling machine not a lathe?
