Help selecting diamond coated burrs for cutting glass

I need to cut a profile of about 34 linear inches around an ovoid in 3/16" mirror glass. I had heard of using diamond coated burrs with lots of coolant and a slow speed. So I tested it and it works with only very, very small micro fractures on the edge. Question though, is where to get high quality burrs as those that I have are the cheap asian type from a kit of several. I looked in MSC and couldn't find anything that stood out. I don't want to have to worry about the burr failing during the cut.

Thanks, I haven't been here in a long time...
