PJs,
The boring boring bars are a super sharp type of cobalt (5%) HSS boring bars honed with an extra fine diamond hone. For health reasons I don't like grinding cobalt HSS cutters but they are very tough. It took about one year to collect the individual boring bars from various KBC Tools sales during their super discount sales days and of course waiting for their back-orders because these were so popular and out of stock.
I have lots of left-over oak, birch, and mahogany from my cabinet milling work. I would like to burn the left-over oak in our fireplaces but would rather keep it for reuse.
Thanks,
Paul
