True, striations should always go with the 'grain' and if not, then a crosshatch pattern if unable to, so in this case where an antioxidant lubricant is desired, the latter is my choice same as when honing a piston ring/cylinder bore.
Why can't they be used in a drill? Too soft?
I noticed that this has been around for decades, dropped and re-issued in 2001, so really surprised I've never seen it mentioned, especially back then when I was browsing dozens of audio/video related forums as well as a few holdout email BBs.
