How to Improve Tapping Operations

       Check the following for Consistent Tapping Performance
  • Proper Tapped Hole Diameter - Small differences in the prepared hole can cause tap breakage, reduce tap life, and increase the torque required

  • Form taps require a larger tap hole and tighter tap hole tolerances than cutting taps

  • Use the lowest percentage thread consistent with the application to reduce tap breakage and increase tap life

  • The "H" classification of the tap determines the tap hole size required - Higher "H" classifications require larger tap hole sizes
