Mitutoyo 568-969 Digital ABS Borematic (Internal) SetInch/metric, 3-4", Complete Unit Set

Part Number : 568-969

Part Number: Mitutoyo 568-969

The Mitutoyo 568-969 Digital ABS Borematic bore gauge set measures internal diameters from 3"–4" (76.2–101.6 mm) with a three-point, self-centring head and an ABSOLUTE digital display. It is supplied as a complete unit set with a setting ring, storage box, key, battery and certificate of inspection, making it ready for precision bore measurement on arrival.

Checking a 3"–4" bore with a conventional dial bore gauge requires a separate indicator, a setting master and a careful sweep to find the turning point. The Mitutoyo 568-969 uses a self-centring three-point measuring head and digital readout to provide the bore diameter directly.

Three evenly spaced contact points help centre the measuring head inside the bore, reducing rocking and the need to search for the turning point associated with traditional two-point and dial bore gauges. Its ABSOLUTE digital encoder retains the zero position even after the gauge is switched off. The display provides 0.00005" / 0.001 mm resolution with Inch/Metric switching.

As a complete unit set, the Mitutoyo 568-969 includes the measuring unit, setting ring, storage box, key, one battery and certificate of inspection. The measuring pins are titanium-coated and the taper is tungsten carbide, making the gauge suitable for repeated measurement applications.

Typical applications include engine cylinder bores, large pump and compressor casings, valve bodies and heavy bearing housings.

For accurate measurements, allow the gauge and workpiece to reach the same temperature before measuring. Temperature differences can affect dimensional readings, particularly when measuring larger steel components.

For smaller bore applications, the Mitutoyo 568-968 covers 2"–3". The Mitutoyo 568-936 interchangeable head set covers 2"–4".

Who This Product Is Best For

  • CNC and conventional machine shops measuring 3"–4" internal bores

  • Oil, gas and utilities maintenance teams in Kuwait

  • Quality-control and inspection teams requiring clear GO/±NG judgment

  • Calibration and metrology laboratories requiring ABSOLUTE-encoder measurement

  • Buyers replacing conventional dial bore gauges with a digital Borematic system

How to Use

  1. Zero the display against the supplied setting ring.

  2. Insert the three-point measuring head squarely into the bore.

  3. Allow the measuring pins to settle against the bore wall.

  4. Read the internal diameter directly from the LCD.

  5. If tolerance limits are configured, check the displayed GO/±NG result.

  6. Use the HOLD function or data output when measurements need to be retained or transferred for SPC records.

Frequently Asked Questions

What bore range does the Mitutoyo 568-969 measure?
The Mitutoyo 568-969 measures internal diameters from 3"–4" (76.2–101.6 mm) and supports Inch/Metric display switching.

How is a three-point Borematic different from a dial bore gauge?
A dial bore gauge generally uses a separate indicator and requires a sweep to locate the turning point. The Borematic uses three contact points to self-centre in the bore and displays the measured diameter digitally.

What comes in the complete unit set?
The set includes the measuring unit, setting ring, storage box, key, one battery and a certificate of inspection.

How long does the battery last?
The supplied specifications indicate approximately 5,000 hours of battery life.

Which Borematic should I choose if my bore is not 3"–4"?
Select a model whose measuring range covers the required bore. The 568-969 covers 3"–4", while the 568-968 covers 2"–3". Other dedicated or interchangeable-head configurations may be suitable for different measurement ranges.

Can the Mitutoyo 568-969 be recalibrated after purchase?
Yes. The gauge can be periodically recalibrated through an appropriate ISO/IEC 17025-accredited calibration service to maintain measurement traceability.

How can I get accurate measurements with the Mitutoyo 568-969?
Allow the gauge and workpiece to reach the same temperature before measurement. Position the three-point head squarely in the bore and allow the measuring contacts to settle before taking the reading.
