More than just a couple of thou. First pass is 0.25, second pass is 17/64. About 0.015 bigger with the reaming pass. Second pass goes very quickly, no drill bit heating or chip clearing issues, and leaves a hole sized more accurately than any other way I've tried. A thousandth or so won't make much of a detectable difference in a more resilient and less dense maple block, but it sure will in the denser blocks like Delignit, and more so in the near granite blocks like Falconwood and the granite+ blocks like Baldwin's.
