oh man, i'm pretty sure this one wasn't $700.. i forget the brand, but there's a catalog around the shop somewhere with different ends and bits. i think it was more like $300 or something? still spendy.
even with the 90deg, it's scary in there..
it has this nut on the back that spins and you gotta keep that off the nikasil or else!
i stick my thumb up next to it so that it never hits
