Nice job on the tools. Did you get the carbide from someplace like mc master - carr or the likes. Only thing that I might do is on the detail tool sweep the round stock back so that it is not square. If you push the detail tool in and it hit the end of the stock you will bind and get a catch grind off some of the stock and that will reduce the chance.
Might want to try some if the machine shops in your area they might sell to you at little to no mark up they have stuff that is very close to what you have posted. Carbide last a long time starts to get dull simply rotate a small amount good to go.
