Hi all,

Still looking for those small etching bits for engraving boards.

T-Tech wants $15.00 a pop for them and it seems there is no one that 
sharpens them.


Three questions,

does anybody have a source for cheap etching bits ?  These are the 60 
deg Vee point engravers.


And, what do you guys pay for them ?   I think $15.00 a pop is a 
little steep.


Third question is what about a group purchase to get discounts on 
costs ?   Probably only good for those of us in the U.S.
