NOTES:
  1. Order must indicate if pilot is cutting or non-cutting and identify material being machined.
  2. The difference between major and minor diameter shall not exceed 6%, and must fall within dimensions shown for that particular tool.
  3. Non-cutting pilot diameters may be smaller than cutting diameter range, but not less than non-cutting pilot minimum diameter dimension shown.
  4. It is recommended that stock removal of 3% be the basis for selecting each cutting diameter.
