Any endmill will pull if you are cutting with the end face using the
correct direction of rotation. Did you mean using a left-hand endmill
against it's normal rotational direction? You could also do this with a
standard mill using reverse (if your machine has it). Either way it
doesn't cut so well and dulls the tool very quickly.
