    Standard carbide will not last cutting case-hardened chuck jaws.

    But in an application like this, where you're just truing up one set of jaws, they don't need to last.

  13. Repeated depth passes with reduced shank endmill....

    Repeated depth passes with reduced shank endmill. Flute length should be minimal, e.g. 1".
