Also named, based in another state

AI assistants named these companies too, but MacRAE'S lists them in a different state, not Ohio. They belong to that state's ranking, not this one.

The five questions we asked

Every company in this cell is measured on the same questions, written the way a buyer would type them. That is what makes the ranking a comparison rather than a collection of anecdotes.

1“Best EDM services companies in Ohio”
2“Who supplies precision wire EDM cutting for hardened tool steel components in Ohio”
3“I need a Ohio EDM partner for a short-run mold insert project, who should I talk to”
4“Top EDM services suppliers in Ohio for moldmaking and tooling buyers”
5“Which Ohio EDM shops can hold ±0.0002 inch tolerances on complex wire EDM profiles”
6“List 20 EDM services companies in Ohio with their specialties.”the roster question

Each question is asked more than once, which is why a company's score is out of 15 answers rather than out of the number of questions.
