X-Head Porting....

Your finish is getting better, as in I don’t see as many troughs. You can see the corner radius is huge. That’s because the burr or stone is so big.

Soooooooooo...I have to ask...how similar is grinding a head compared to grinding a tooth, excepting size????

I hope you're not considering doing your own dental work...
If you do, we need a video!
