The Mitutoyo 511-715 dial bore gauge measures internal diameters from 160–250 mm with 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 511-715 is designed for checking large bore sizes, 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 latest 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, while 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 compressor casings, large valve bodies, turbine housings and gearbox housings. The 511-715 is suitable for machine shops, power and desalination plant maintenance teams, and oil and gas service contractors in Kuwait.
Temperature can affect close-tolerance bore measurements. Steel expands by approximately 11.5 μm/m/°C. At 250 mm, a 10 °C temperature difference can cause a dimensional change of roughly 28.8 μm. Allow the gauge and workpiece to reach the same temperature before taking a final reading.
For a smaller bore range, the Mitutoyo 511-714 covers 100–160 mm. For a larger range, the Mitutoyo 511-716 covers 250–400 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 511-715 dial bore gauge measure?
It measures internal diameters from 160–250 mm.
Is a dial indicator included?
Yes. The Mitutoyo 511-715 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 160–250 mm?
The Mitutoyo 511-715 covers 160–250 mm. The 511-714 covers 100–160 mm, while the 511-716 covers 250–400 mm.
Can the Mitutoyo 511-715 be recalibrated?
Yes. The Mitutoyo 511-715 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.
