I was at work when I noticed one of the machinists flycutting a piece of aluminum on one of the Bridgeports. The surface finish he was getting was amazing. I stopped and asked him how he ground the cutter. Not only did he show me, he was kind enough to grind one for me.
I brought it home, put it in my fly cutter and got terrific results.
So, I thought I'd share his grind with you guys. Rather than try to explain it, I took closeup pictures. This bit started life as a brazed carbide AL (left hand) bit. I don't see any reason this couldn't be duplicated in HSS.
Here are the pictures... Note the slight radius appiled to the cuitting edge...
