    I'd guess it isn't o1 or it wasn't 800C (maybe 800F?) or the oil isn't what you think.
    Was it red hot when you quenched? Non-magnetic?
    Take the same material and revert to your old method (veg oil). Does that work? If so, that oil isn't like Parks 50.

    I prefer diamond plates for flat areas. You can hold them in a hand vice and use them like files. 6"x2 or 4"x1 cheap off amazon.
    I do use EDM for other things.
