Thought that I had found a hidden gem, but it seems lots of you already have them.
I already have a few of the smaller sizes of the Chinese gold coloured ones but they are far better than those, in particular the accuracy of the sizing.
They are within a few microns of the listed sizes, which is very rare for relatively low cost drills, a trait normally found in expensive Dormer and the like.
Try this one then, but I suspect many of you guys already know it.
Mike.
