• Compact and lightweight due to the short length below the grip.
  • Longer plunger stroke with no affect on accuracy.
  • Carbide contact point ensuring high durability and wear resistance.
  • This model reduces the influence of heat from the operator’s hand by 50% by increasing the grip size and making the grip hollow-structured, thereby retaining high-accuracy measurement.
  • Alternative indicators may be used in plathose 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.
  • 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.)
