I found these blades to be real junk and found absolutely no advantage to using them especially for the higher price. Irons always seem to be best cut with a band saw by an experienced technician. Why cut a Nantan? You are asking for trouble....that sucker will likely rust in front of your eyes!!

I purchased a 10-inch Pro-Slicer (10 x 0.012) CBN blade from Lapidary Discounts in California and used it to cut a 2 1/2 inch Nantan. It worked very well for the first 10 cuts, then, very quuckly, started to bind up indicating that the CBN was gone from the blade. For the cost I expected to get much longer life from it. Any opinions on what kind of a life one can expect from such a blade. Altogether I cut about 22 linear inches before the blade was useless. I think I followed good cutting practices, using pella oil for lubrication, and feeding at a rate of about 1 inch every 5 minutes (0.2 inch per minute). Motor speed was 1750 rpm. Any ideas?
