Hi Larry,
I agree that the wall thickness is definitely something to consider when it comes to very long increment borers. Do you know if the wall thickness increases with length on Haglöf borers? I hear that Sweden has access to some very high quality iron ore deposits which they use to make what one guy described as high yield "unobtanium" alloyed tubes from companies such as Sandvik.
