I found a D.B. Die Works n. 39 kick press on marketplace recently, it came without dies, the diameter of the holes on my press is 9mm (I used a caliper tool to figure out the diameter of the hole, which I recommend you do the same) -- I figured out Tandy Leather dies fit nicely, I tried to use other brands but found the height on the DB die works press was too high for most. If your press also takes 9mm dies then I recommend seeing if their 'hand press dies' work, the rivet dies at tandy come in a three pack and they have line snap dies.
