And it turns out when googling, that part number is a 1/16" radius bit, no damned wonder its not doing the job! Amazon miss-described it. Thats twice they've bit my ass in the last month. And the only hit I can get on a 1/8" radius pointed round over is at Carbide Processors, at $108 a copy that is un-obtainium personified! Does anyone else have better google foo than that? I have some diamond burrs for a dremel. I might be able to make these 3 $13 versions into a more pleasing profile on the toy mill. > 2.
