General Tech Services LLC — Genuine Mitutoyo Distributor, Kuwait +965 9807 4888
The Mitutoyo 511-711 dial bore gauge measures internal diameters from 18–35 mm using a self-centring two-point head and a 0.01 mm dial indicator. Carbide contact points and a heat-insulating grip support stable readings during repeated inspections. Request a quote in under a minute: call or WhatsApp +965 9807 4888.
Product Overview
The Mitutoyo 511-711 is designed for checking bore size, taper and ovality where a standard caliper may not provide the required measurement capability. Its two-point measuring head incorporates a centring guide that helps align the gauge across the true diameter as it is gently rocked through the bore.
The 511 series design provides a longer plunger stroke while maintaining its established measurement performance. A carbide contact point provides wear resistance, while the larger hollow grip reduces heat transfer from the operator's hand by 50%, helping maintain measurement stability during extended inspection runs.
Interchangeable 0.5 mm washers allow fine step adjustment of the anvils, and optional extension rods provide additional reach for deeper bores. For measurement setup, the gauge can be set using a setting ring or optional Inside Micro Checker.
Typical applications include bearing seats, hydraulic cylinder bores, pump housings and gearbox bores. The gauge is suitable for oil and gas maintenance workshops, refinery and petrochemical shutdown crews, and CNC machine shops across Kuwait.
Temperature can affect close-tolerance bore measurements. Steel expands by approximately 11.5 μm/m/°C. At 35 mm, a 10 °C temperature difference can produce a dimensional change of roughly 4.0 μm. Allow the workpiece and gauge to reach the same temperature before taking a final reading.
For a larger bore range, the Mitutoyo 511-712 covers 35–60 mm.

How to Measure a Bore With This Gauge
-
Fit the appropriate anvil or 0.5 mm washer combination for the nominal bore size.
-
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 0.01 mm dial indicator.
-
Record the deviation from nominal.
-
Repeat measurements at different depths and positions to check for taper and ovality.
Frequently Asked Questions
What range does the Mitutoyo 511-711 dial bore gauge measure?
It measures internal diameters from 18–35 mm.
Is a dial indicator included?
Yes. The Mitutoyo 511-711 is supplied with a 0.01 mm dial 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 and measurement stability. The larger insulating grip reduces heat transfer by 50%.
Which model should I choose if my part is outside 18–35 mm?
The Mitutoyo 511-711 covers 18–35 mm. For a larger bore range, the Mitutoyo 511-712 covers 35–60 mm.
Can the Mitutoyo 511-711 be recalibrated?
Yes. The Mitutoyo 511-711 can be periodically calibrated through an ISO/IEC 17025-accredited calibration service to help maintain measurement traceability.
How should I store and care for it?
Wipe the measuring faces clean after use, store the instrument in its case away from direct sunlight and coolant, and avoid dropping or impacting it. Check the measurement setup regularly and maintain periodic calibration where traceability is required.
