Product Overview
The Mitutoyo 511-702 is designed for shops that already have compatible dial or Digimatic indicators or need a specific indicator graduation for their measurement requirements. The gauge uses a self-centring guide and Mitutoyo 511-series contact geometry for inside-diameter measurement.
A carbide contact point provides long wear life, while interchangeable 0.5 mm washers allow fine setting for the required nominal size. Optional extension rods can be used where deeper bores require additional reach.
Typical applications include bearing seats, hydraulic cylinder bores, pump housings and gearbox bores. It is suitable for machine shops, QC teams, power and desalination plant maintenance teams, and oil and gas service contractors in Kuwait.
For best measurement stability, allow the gauge and workpiece to reach the same temperature before measuring. Steel expands by approximately 11.5 μm/m/°C; at 60 mm, a 10 °C temperature difference can shift the dimension by approximately 6.9 μm.
For a complete gauge with the same 35–60 mm range and a 0.01 mm dial indicator, consider the Mitutoyo 511-712. For a larger range, the Mitutoyo 511-703 covers 50–150 mm.

How to Measure a Bore With This Gauge
-
Fit the appropriate anvil or 0.5 mm washer combination for the nominal bore size.
-
Install a suitable compatible dial or Digimatic indicator.
-
Set the gauge to zero using a setting ring or master of known size.
-
Insert the gauge into the bore and gently rock it through the measuring position.
-
Read the turning point on the indicator and record the deviation from nominal.
-
Repeat the measurement at different depths and positions to check for taper and ovality.
Frequently Asked Questions
What range does the Mitutoyo 511-702 bore gauge measure?
It measures internal diameters from 35–60 mm.
Is a dial indicator included?
No. The Mitutoyo 511-702 is supplied as the gauge body without an indicator, allowing you to fit a suitable dial or Digimatic indicator.
Do I need a setting ring?
A setting ring or master of known size is recommended for setting the gauge before measurement and achieving reliable results.
Why does the grip matter?
Heat transferred from the operator's hand can affect the gauge dimension and measurement stability. The larger insulating grip is designed to reduce hand heat transfer by 50%.
Which model should I choose if my part is outside 35–60 mm?
The 511-702 covers 35–60 mm. The Mitutoyo 511-701 covers 18–35 mm, while the Mitutoyo 511-703 covers 50–150 mm.
Can the Mitutoyo 511-702 be recalibrated?
Yes. Periodic calibration through an ISO/IEC 17025-accredited calibration service can help maintain measurement traceability.
How should I store and care for it?
Clean the measuring faces after use, protect the instrument from coolant and direct sunlight, avoid impacts or dropping, and check the measurement setup regularly. Periodic calibration should also be maintained where traceability is required.
