Mitutoyo 568-929 Digital ABS Borematic (Internal) Set Inch/Metric, 0.5-1", Interch. Head Set

The Mitutoyo 568-929 is a digital ABSOLUTE bore gauge set covering 0.5" – 1", built around a single display unit with interchangeable measuring heads instead of a separate gauge for every bore size. It suits shops running several bore ranges who want to standardise on one display.

Part No. 568-929 | Range 0.5" – 1"

Stocking a complete ABSOLUTE Borematic gauge for every bore diameter a shop checks adds up quickly in both cost and storage space. The Mitutoyo 568-929 solves this with an
interchangeable head design: one ABSOLUTE digital display unit accepts different three-point measuring heads, so the 0.5" – 1" range is covered by swapping the head rather than buying a second complete gauge.

The shared display uses the same ABSOLUTE digital encoder as the complete-unit sets, so
readings appear instantly the moment the head contacts the bore wall, with no re-zeroing step and no mechanical dial to drift over time. The 330° rotatable display lets the operator read the value comfortably whether the part sits on a bench or in an awkward fixture.

A GO/+/-NG judgment function is built into the LCD, so a pass or fail decision is visible
immediately rather than checked against a separate tolerance chart. With approximately 5,000 hours of battery life, the set is built for daily use on a busy inspection line, not just occasional spot checks.

If you need a different range on the same interchangeable-head system, the 568-928 covers 0.257"–0.5", so you can expand your head set without buying a second display — see the Mitutoyo 568-928.

Key Benefits

• One display unit, multiple ranges — swap measuring heads instead of buying a full gauge for every bore size
• Instant, drift-free readings — the ABSOLUTE digital display removes the guesswork of dial- based bore gauges
• Read from any angle — a 330° rotatable display head means no awkward twisting during inspection
• Built to last — titanium-coated measuring pins resist wear from daily production use
• Faster quality checks — GO/+/-NG judgment flags out-of-tolerance parts immediately
• Long runtime — approximately 5,000 hours of battery life reduces downtime for battery changes

Who This Product Is Best For

• Machine shops running multiple bore sizes who want one display unit instead of several complete gauges
• Quality control teams who need GO/NG pass-fail decisions directly on the production line
• Calibration and metrology labs standardising on a single ABSOLUTE display across several head ranges
• Buyers who already own a compatible ABSOLUTE Borematic display and need an additional range

How to Measure a Bore With This Gauge

1. Fit the measuring head for your bore range onto the shared ABSOLUTE display unit and zero against the setting ring.
2. Insert the three-point head into the bore and let the contact points settle against the wall.
3. Read the LCD instantly — the ABSOLUTE display shows the diameter directly, with a GO/+/-NG result if tolerance limits are set.

Frequently Asked Questions

What range does the Mitutoyo 568-929 bore gauge measure?

The 568-929 covers internal bores from 0.5" – 1", with Inch/Metric switching built into the
digital display.

How is an interchangeable head set different from a complete unit set?

A complete unit set is one dedicated gauge for one range. An interchangeable head set uses a single ABSOLUTE display unit with swappable three-point measuring heads, so covering several ranges means buying additional heads rather than additional displays.

Does this set include a GO/NG tolerance check?

Yes. The 568-929 has a built-in GO/+/-NG judgment function on its LCD, so operators see a pass/fail result immediately rather than comparing readings to a separate chart.

What comes in the set?

The set includes the measuring unit, a storage box, key, one battery, and a certificate of
inspection.

How long does the battery last?

Approximately 5,000 hours of continuous use before a replacement is needed.

Which head should I choose for a different bore size?

The 568-928 covers 0.257"–0.5" on the same interchangeable-head display system, so you can add heads for other ranges without buying another gauge body.

Can this gauge be calibrated after purchase?

Yes. The set ships with a certificate of inspection and can be re-calibrated through a 17025-accredited calibration service to maintain measurement accuracy over time.
