Testing a Vevor 800W EDM machine designed for broken tap removal. There are several versions of this on Aliexpress and similar - my test part was simple enough to recreate, but wanted to know if in the future could have an easier way to remove a broken tap. In this case it broke off well inside the part because the upper half was a clearance hole, so removed from the "untapped" side instead (which wouldn't be possible with a normal tap remover).

See a nice description in the comments by @ArionRaine for how the EDM/servo method works! Makes more sense when you see it!
