Thanks guys, the white stripe is indeed nice. I set it up to run across like that, but of course had no real idea exactly where it would turn up.
I get these bits at a local machine shop which makes them. Pretty sure they do mail order, and they sell a bit on ebay too, real nice guys there. I went a few weeks ago and bought 4 bits, and he gave me 2 nice bits as samples. Here is their contact info
