Product Overview

The Mitutoyo 511-701 is a two-point bore gauge body designed specifically for inside diameter measurement. It uses a self-centring guide and contact geometry from the Mitutoyo 511 series to support repeatable bore inspection.

Because the indicator is not included, this configuration is useful for workshops that already have compatible dial or Digimatic indicators or require a particular graduation for a specific measurement task.

Interchangeable 0.5 mm washers provide fine setting increments, while carbide contact points provide wear resistance for repeated measurements. Optional extension rods can be used when additional reach is required.

Typical applications include bearing seats, hydraulic cylinder bores, pump housings and gearbox bores. The 511-701 is suitable for oil and gas maintenance workshops, refinery and petrochemical shutdown crews, CNC machine shops and other industrial maintenance operations across Kuwait.

Temperature can affect precision dimensional measurements. Steel expands by approximately 11.5 μm per metre per °C. At 35 mm, a 10°C temperature difference can change the dimension by approximately 4.0 μm. Allow the workpiece and gauge to reach the same temperature before taking a final reading.

For a ready-to-use configuration covering the same range, the Mitutoyo 511-711 is supplied with a 0.01 mm dial indicator.

For a larger bore range, the Mitutoyo 511-702 covers 35–60 mm.

Key Benefits

• Self-centring — the guide helps align the measuring head with the true bore diameter.

• Carbide contact point — provides long wear life.

• Choose your indicator — pair the gauge body with a suitable dial or Digimatic indicator.

• Fine setting — interchangeable 0.5 mm washers support small setting adjustments.

• Deep-hole ready — optional extension rods provide additional reach when required.

• Indicator flexibility — suitable for applications requiring a specific indicator graduation.

• Mitutoyo 511 series — established bore gauge design for workshop and quality-control applications.

Who This Product Is Best For

• Machine shops checking bearing seats and precision bores.

• QC teams measuring bore size, taper and ovality.

• Maintenance teams inspecting hydraulic cylinder, pump and gearbox bores.

• Oil and gas maintenance workshops.

• Refinery and petrochemical shutdown crews.

• CNC machine shops requiring a flexible bore gauge body.

• Engine, pump and hydraulic rebuild workshops.

• Buyers who already have suitable dial or Digimatic indicators and want a compatible Mitutoyo bore gauge body.

How to Measure a Bore With This Gauge

1. Fit the appropriate anvil or 0.5 mm washer combination for the nominal bore size.

2. Attach a suitable compatible dial or Digimatic indicator.

3. Set the gauge to zero against a setting ring or master of known size.

4. Insert the gauge into the bore carefully.

5. Rock the gauge gently through the bore and identify the turning point on the indicator.

6. Record the deviation from the nominal dimension.

7. Repeat measurements at different depths and positions to check for taper and ovality.

Frequently Asked Questions

What range does the Mitutoyo 511-701 bore gauge measure?

It measures internal diameters from 18–35 mm.

Is a dial indicator included?

No. The Mitutoyo 511-701 is supplied as the gauge body only, allowing you to fit a suitable dial or Digimatic indicator for your application.

What type of indicator can I use with the 511-701?

The gauge body is designed to be paired with a suitable dial or Digimatic indicator according to the required measurement resolution and application.

Do I need a setting ring?

A setting ring or master of known size is recommended for setting the gauge before measurement and achieving accurate readings.

Can the Mitutoyo 511-701 measure taper and ovality?

Yes. Take measurements at different depths and positions within the bore to identify changes in diameter.

Can it be used for deeper bores?

Optional extension rods can be used when additional reach is required.

Which Mitutoyo model covers a larger bore range?

The Mitutoyo 511-702 covers 35–60 mm, while the 511-701 covers 18–35 mm.

Is there a complete Mitutoyo gauge for the same range?

Yes. The Mitutoyo 511-711 covers 18–35 mm and is supplied with a 0.01 mm dial indicator.

Can the Mitutoyo 511-701 be recalibrated?

Yes. Periodic calibration through an ISO/IEC 17025-accredited calibration service can help maintain measurement traceability. The fitted indicator should also be calibrated as applicable.

How should I store and care for the gauge?

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 measurement setup before use and arrange periodic calibration as required.
