• Capable of ID (inside diameter) measurement close to the bottom of a hole.
  • Carbide contact point ensuring high durability and wear resistance.
  • Grip is large and hollow to reduce effect of body heat on high-accuracy measurements.
  • Alternative indicators may be used in place of those recommended*.
    * Some indicators and protection covers cannot be used with these bore gages. Contact a Mitutoyo sales office if considering the use of dial or digimatic indicators other than the recommended models.
  • Optional extension rods can be attached for measuring deep holes. (For details, refer to page C-45.)
  • A Bore Gage Checker and a range of Setting Rings are available to aid in accurately setting a gage before making a measurement. (For details, refer to pages C-46 and C-47.)
