Mitutoyo 568-461 Digital ABS Borematic Bore Gauge, 0.275" – 0.35" (Inch/Metric)
Part Number: Mitutoyo 568-461
The Mitutoyo 568-461 digital bore gauge is a dedicated, single-range internal micrometer for bores of 0.275"–0.35" (6.985–8.89 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 any kit. The Mitutoyo 568-461 digital bore gauge is built for one range, 0.275"–0.35" (6.985–8.89 mm), with the head and ABSOLUTE display permanently paired, so there is nothing to assemble before measuring.
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 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 a natural fit for small hydraulic valve bores, fuel-system components, spool housings and precision bushings.
Temperature matters in Kuwait's climate. Steel grows about 11.5 μm per metre for every 1 °C, so a 10 mm part carried from a hot bay into an air-conditioned inspection room can change by roughly 1.1 μm over a 10 °C swing. Let the part and the Mitutoyo 568-461 digital bore gauge settle to the same temperature before taking a final reading.
Need a larger range? The Mitutoyo 568-462 covers 0.35"–0.425". Measuring several neighbouring sizes? The Mitutoyo 568-965 complete set also covers 0.275"–0.35".
Key Benefits
-
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.
-
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 support quality records.

Who This Product Is Best For
-
CNC and conventional machine shops holding tight tolerances on 0.275"–0.35" bores.
-
Oil, gas and utilities maintenance teams in Kuwait checking small hydraulic valve 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 the Mitutoyo 568-461 digital bore gauge to cut 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 568-461 digital bore gauge measure?
It measures internal diameters from 0.275"–0.35" (6.985–8.89 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.
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 0.275"–0.35"?
Choose the model whose range brackets your nominal bore with a suitable margin. The 568-461 suits 0.275"–0.35"; the Mitutoyo 568-462 covers 0.35"–0.425". If you measure several sizes in this band, the Mitutoyo 568-965 complete set covers 0.275"–0.5".
Can the gauge be recalibrated after purchase?
Yes. The Mitutoyo 568-461 digital bore gauge can be recalibrated periodically through an ISO/IEC 17025-accredited calibration service to keep readings traceable.
