Shariff DMC2: CNC Coins and breaking the DMC2.

I cover the process of making some challenge coins as a gift. There were several problems in the process, ordering the wrong blanks, breaking the last of my favorite cutters and even breaking the DMC2. But it all worked out in the end.

Here is the link to the 60 degree 1/8" V bits I used on the copper and brass. They are ok but not great. If you do an extra finish pass and plan on polishing or deburring by hand, they are fine. The tips will break after a few uses (I'm guessing they dull just enough to create heat, gum up then chip because they are not cutting) I broke 2 doing 2 coins (4 sides) and ended with the 3rd.
On the plus side, they are cheap and got me through since I was running out of time to get this project done.
