Install NEI to see the correct recipe for whatever version of IC2exp you've installed. Also, it's better to specify the build number rather than just say "the latest", in case a build goes up between you installing the mod and someone else replying.
Anyway, I'm still on build 667, in which the diamond drill requires an iron turning blank, and looking at the changes in Jenkins, it probably has since build 659.
