I've been learning how bad the low cost brazed carbide boring bars are (incorrectly ground) and was looking for indexable carbide - but saw these C12 babies and went for them. Now in hand, I half fear they are ground as badly as the brazed bars (not totally confirmed yet) but at least I can grind them.
Def take a look at their dial indicator! There is a video there of a fellow running accuracy test on the Shars and other top names - and it came out with FLYING colors - for $11!
