The commercial stuff for that would be something like cast tetrahedral stars, that gives the points to reach into holes and edges to wear off the flash/slag/dross.
In practice all the small bits of scrap coming off the bandsaw, and your cutting scraps will work fine.
The parts will also wear against each other. When I tumble the chasing tools it burnishes the hardened ends and deburrs the edges of the struck end.
If all the edges of your parts are critical and need to be protected, you may need to float them in enough media that they only tend to bump into each other occasionally. A vibratory tumbler would be best then.
