    I'm not sure what you're asking.
    Are you looking for a recommendation for magnets to hold slugs as you cut them free so they don't foul the lower head?

    Hi RJT:
    How successful have you been trying to sinker EDM titanium in general?
    I have found that significant electrode wear is a big issue.

    Good morning cc22288:
