Where is the file to load this into my tool database in my CNC software program?

Sorry we do not have the files. The manufacturer's image should have a 2D diagram that can be traced.

What is the diameter in mm?

The cutting diameter is 1/8" which is 3.175mm. The shank is 1/4" which is 6.35mm

We do have tapered ones but this bit is not tapered.

What is the helix angle of this bit?

It's a 33 degree sheer. The manufacturer's image has the information but Amazon removed it.
