Mitutoyo 568-930 Digital ABS Borematic (Internal) Set Inch/Metric,1-2", Interch. Head Set
Part Number: Mitutoyo 568-930
The Mitutoyo 568-930 interchangeable head bore gauge covers 1"–2" (25.4–50.8 mm) using one ABSOLUTE digital display and a set of three-point measuring heads that swap in seconds. One kit replaces several single-range gauges on the bench. Request a quote in under a minute: call or WhatsApp +965 9807 4888.
Workshops that see a mix of bore sizes between 1"–2" often end up with a drawer full of single-range gauges. The Mitutoyo 568-930 interchangeable head bore gauge solves that with one ABSOLUTE digital display unit and interchangeable three-point heads, so the operator changes the head instead of the whole instrument.
A two-point gauge can sit off-centre and read short. Three contact points centre the head in the bore on their own, so the reading reflects the true diameter rather than the operator's hand. With an ABSOLUTE digital encoder, the gauge holds its zero point even after being switched off. The display resolves to 0.00005" / 0.001 mm with Inch/Metric switching.
The kit ships with the measuring unit, a storage box, a key, one battery and a certificate of inspection. Titanium-coated pins resist wear from daily contact with machined steel. Typical work includes gearbox housings, pneumatic cylinder bores, compressor components and bearing housings.
Keep the contact faces clean and store the Mitutoyo 568-930 interchangeable head bore gauge in its case between jobs. In hot Kuwait workshops, also allow the part to cool: at 50.8 mm, a 10 °C temperature gap moves a steel part by roughly 5.8 μm, more than the resolution of a precision instrument.
Need a larger range? The Mitutoyo 568-936 covers 2"–4". The Mitutoyo 568-967 complete unit set starts at the same size and includes a setting ring.
Key Benefits
-
One display, several ranges — Swap heads to cover the full span of the kit.
-
Pass/fail on the display — GO/±NG judgment flags out-of-tolerance bores without a tolerance chart.
-
Read from any angle — The LCD rotates through 330° for awkward fixtures and deep parts.
-
Built for daily use — Titanium-coated pins resist wear and impact.
-
SPC-ready — HOLD function and data output support quality records.
-
Self-centring accuracy — Three contact points align the head on the bore axis for repeatable readings.
-
Instant digital readings — ABSOLUTE encoder, no re-zeroing at power-on and 0.001 mm resolution.

Who This Product Is Best For
-
CNC and conventional machine shops holding tight tolerances on 1"–2" bores.
-
Job shops with mixed bore sizes that want one display for several heads.
-
Oil, gas and utilities maintenance teams in Kuwait checking gearbox housings.
-
QC and inspection teams that need a clear GO/NG decision at the machine.
-
Calibration and metrology labs that want ABSOLUTE-encoder repeatability.
-
Buyers replacing analog dial bore gauges with the Mitutoyo 568-930 interchangeable head bore gauge to cut setup time and reading error.
How to Use
-
Fit the measuring head that matches the nominal bore size.
-
Zero the display against a setting ring or master of known size within the range.
-
Insert the three-point head squarely into the bore and let the pins settle against the wall.
-
Read the diameter on the LCD; if tolerance limits are set, the GO/±NG result appears alongside.
-
Press HOLD or send the value to your data logger for SPC records.
Frequently Asked Questions
What bore range does the Mitutoyo 568-930 interchangeable head bore gauge measure?
It measures internal diameters from 1"–2" (25.4–50.8 mm), with Inch/Metric switching on the display.
How is a three-point Borematic different from a dial bore gauge?
A dial bore gauge needs a separate indicator and a sweep to find the turning point. The Borematic self-centres on three points and shows the diameter directly on an ABSOLUTE digital display, which cuts setup time and operator error.
What does interchangeable head mean?
One digital display unit accepts several three-point heads. You fit the head that matches the bore and measure, so a single kit covers 1"–2".
How long does the battery last?
Approximately 5,000 hours of use before it needs replacing.
Which Borematic should I choose if my bore is not 1"–2"?
Choose the model whose range brackets your nominal bore with a suitable margin. The 568-930 suits 1"–2"; the Mitutoyo 568-929 covers 0.5"–1", while the Mitutoyo 568-936 covers 2"–4". If you only ever check one size, a dedicated individual unit such as the Mitutoyo 568-467 (1"–1.2") may be suitable.
Can the gauge be recalibrated after purchase?
Yes. The Mitutoyo 568-930 interchangeable head bore gauge can be recalibrated periodically through an ISO/IEC 17025-accredited calibration service to keep readings traceable.
