How to select the correct undersized reamer for a 1/4-inch hole?

For a 1/4-inch finished hole, select an undersized reamer like the YANKEE 1435-0.2490, which cuts 0.001 inch under nominal size. This allows for final sizing with a separate finishing reamer or burnishing. Always match flute type (spiral for chip evacuation) and material (cobalt for harder workpieces).
