Eddy RPM heads: Should I be concerned about this casting defect?

Send them back. The only way things are going to improve is if people stop accepting sub-standard products. If enough people start returning these heads, they will hopefully improve the QA process and everyone benefits. If people keep accepting crap, then crap is what they will keep making.

The tiny little spot that I can see on this head doesn't deserve the hammering I'm reading in my opinion.
If it is sent back it will be sold again. We might even see it ebay... with a discount and without mfgs warranty of course.
And by the way .. Recon the Chinaman would just Keep cutting it down until it did clean up ? I would bet on it. Want a thinner head or it's geometry fudged ?
I know for a fact that American Mfgrs cannot pay their help to run the same part repeatedly. I'll bet they toss those nearly completed heads for a tap broke off in them. China would not. Their labor cost is much less.
Lots of parts can't be ran in CNC a second time anyway.
