A part of the review has been auto-translated.
These tungsten carbide boring bars are excellent for very small bores. They are perfectly ground and cut beautifully. These used to be very hard to find so Im really pleased to be able to buy them now.

now I can bore holes that I couldn't get into with my 7mm boring bar. great surface finish Had to make a special holder to hold it in my QCTP.
Perfect for boring small holes very accurately. Indispensable tool to have for the lathe.
