Notes:

  1. This information was obtained from the “Machinery’s Handbook.” It is consistent with the data in the handbook, and is intended to serve as a starting point only.
  2. The recommended RPM is consistent with a surface velocity of the cutter of 100-200 feet per minute.
  3. The recommended RPM is consistent with a surface velocity of the cutter of 200-600 feet per minute.
    * “A”size groove cutters are not recommended by Spira.
