I just got some 1/8" diam x 1.5" Mitsubishi C4 carbide rods
from eBay that seem to have a nice polish on them, but under
30x magnification they are covered with fine scratches.
Does anyone have any recommendations for polishing
techniques for carbide rods? I am guessing that diamond
polish is required.
