Product Overview
The Mitutoyo 511-935 dial bore gauge set covers internal diameters from 0.7"–6" (17.78–152.4 mm) in one interchangeable system. Its self-centring bridge helps align the measuring head with the true bore diameter, while interchangeable anvils allow the set to cover a broad range of internal dimensions.
The carbide contact point provides wear resistance for repeated measurements, and the hollow-structure grip reduces heat transfer from the operator's hand by 50%. The set is supplied with a digital indicator, allowing measurements to be displayed directly and, where supported by the indicator, transferred to a data-collection system.
Typical applications include engine cylinders, pump casings, valve bodies and large bearing housings. The 511-935 is suited to oil and gas maintenance workshops, refinery and petrochemical shutdown teams, CNC machine shops and industrial inspection teams in Kuwait.
Temperature control is important for close-tolerance bore measurement. Steel expands by approximately 11.5 μm per metre per °C. At 152.4 mm, a 10°C temperature difference can correspond to approximately 17.5 μm of dimensional change. Allow the workpiece and the Mitutoyo 511-935 to reach the same temperature before taking a final reading.

How to Measure a Bore With This Gauge
-
Select the appropriate anvil and 0.5 mm washer combination for the nominal bore size.
-
Set the gauge against a setting ring or master of known size and establish the reference.
-
Insert the gauge into the bore and gently rock it through the measuring position.
-
Identify the turning point on the digital indicator and record the deviation from the reference dimension.
-
Repeat measurements at different depths and positions when checking for taper or ovality.
-
Keep the gauge and workpiece at the same temperature before taking the final reading.
Frequently Asked Questions
What range does the Mitutoyo 511-935 dial bore gauge set measure?
It measures internal diameters from 0.7"–6" (17.78–152.4 mm).
Is a digital indicator included?
Yes. The Mitutoyo 511-935 is supplied with a digital indicator.
Does the digital indicator support data collection?
Measurements can be transferred to a data-collection system where the supplied indicator and connected setup support that function.
Do I need a setting ring?
A setting ring or master of known size is used to establish the reference before measurement and helps maintain consistent results.
Why does the grip matter?
Heat from the operator's hand can affect dimensional stability. The hollow-structure insulating grip reduces heat transfer from the hand by 50%.
What is the difference between the 511-932 and 511-935?
Both models cover 0.7"–6" (17.78–152.4 mm) with 0.0001" resolution. The 511-932 uses a dial indicator, while the 511-935 is supplied with a digital indicator.
Which model should I choose if my part is outside the 0.7"–6" range?
Choose a Mitutoyo bore gauge whose measuring range covers the required internal diameter. The 511-series includes models for different bore sizes and measurement requirements.
Can the Mitutoyo 511-935 be recalibrated?
Yes. Periodic recalibration through an ISO/IEC 17025-accredited calibration service can help maintain measurement traceability.
How should I store and care for the gauge set?
Wipe the measuring faces clean after use, store the instrument in its case away from direct sunlight and coolant, and avoid dropping it. Check the reference before each inspection and schedule periodic calibration as required.
