The Mitutoyo Series 511 Bore Gages are engineered specifically for inside diameter (ID) measurements close to the bottom of a blind hole. Featuring high-durability carbide contact points and a large, hollow grip designed to minimize thermal transfer from operator body heat, these instruments deliver reliable, high-accuracy dimensional verification across metric and inch configurations.
- Blind Hole Measurement: Capable of inside diameter measurement in close proximity to the bottom of a hole.
- Carbide Contact Points: Ensures high durability and exceptional wear resistance.
- Thermal Insulation: Large and hollow grip design minimizes the effect of body heat on high-accuracy measurements.
- Indicator Flexibility: Alternative indicators may be used in place of recommended models (note: certain indicators and protection covers cannot be used with these bore gages; contact Mitutoyo for compatibility).
- Deep Hole Compatibility: Optional extension rods can be attached for measuring deep holes (refer to page C-45).
- Calibration Support: Bore Gage Checkers and setting rings are available to aid in accurate gage setup prior to measurement (refer to pages C-46 and C-47).
