Mitutoyo 568-475 Digital ABS Borematic (Internal) Inch/Metric, 4.5-5"
Part Number: Mitutoyo 568-475
The Mitutoyo 568-475 digital bore gauge is a dedicated, single-range internal micrometer for bores of 4.5"–5" (114.3–127 mm). Its three-point head self-centres and the ABSOLUTE display shows the diameter instantly, with a GO/±NG result when limits are set. Request a quote in under a minute: call or WhatsApp +965 9807 4888.
When the same bore size comes up every day, a dedicated gauge is faster than a kit. The Mitutoyo 568-475 digital bore gauge is built for one range, 4.5"–5" (114.3–127 mm), with the head and ABSOLUTE display permanently paired, so there is nothing to assemble before measuring.
Three evenly spaced contact points self-centre inside the bore. This reduces the rocking and hunting for the turning point associated with two-point and dial bore gauges. The ABSOLUTE encoder remembers its origin, so there is no re-zeroing each time the gauge is switched on. Readings appear directly on the LCD at 0.00005" / 0.001 mm resolution.
The 330° rotatable display can be read at bench height or deep inside a fixture, and the GO/±NG judgment function flags out-of-tolerance parts on the spot. It is suitable for engine cylinder bores, large pump and compressor casings, valve bodies and heavy bearing housings.
For the best results, let the Mitutoyo 568-475 digital bore gauge and the part reach the same temperature before measuring. Steel expands about 11.5 μm per metre per °C, so at 127 mm a 10 °C temperature difference can shift the reading by around 14.6 μm.

Key Benefits
-
Instant digital readings — ABSOLUTE encoder, no re-zeroing at power-on and 0.001 mm resolution
-
Dedicated to one size — no heads to change, ideal for repeat production checks
-
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 for quality records
-
Self-centring accuracy — three contact points align the head on the bore axis for repeatable readings

Who This Product Is Best For
-
CNC and conventional machine shops holding tight tolerances on 4.5"–5" bores
-
Oil, gas and utilities maintenance teams in Kuwait checking engine cylinder bores
-
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 a digital Borematic to reduce setup time and reading error
How to Use
-
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 568-475 digital bore gauge measure?
It measures internal diameters from 4.5"–5" (114.3–127 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, helping reduce setup time and operator error.
Is a setting ring included with this individual unit?
No. The unit ships with a storage box, key, one battery and a certificate of inspection. Zero it on a setting ring or master of known size, which can be quoted with the gauge.
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 4.5"–5"?
Choose the model whose range matches your nominal bore. The 568-475 suits 4.5"–5", while the Mitutoyo 568-474 covers 4"–4.5".
Can the gauge be recalibrated after purchase?
Yes. The Mitutoyo 568-475 digital bore gauge can be recalibrated periodically through an ISO/IEC 17025-accredited calibration service to help maintain measurement traceability.
