Product Overview
Workshops that measure many different bore sizes often need a separate bore micrometer for each range, increasing equipment cost and storage requirements. The Mitutoyo 468-979 set covers 2-4" using interchangeable heads on one digital body.
Each head uses the three-point, self-centring measuring principle, allowing the contacts to locate against the bore and provide an inside-diameter reading. TiN-coated contact points provide durability, while IP65 protection makes the set suitable for environments where coolant and dust may be present. It is genuine Mitutoyo, supplied through an authorised distributor.
Typical applications include workshops measuring many different bore sizes, maintenance teams needing one kit for multiple ranges, and quality laboratories standardising on Mitutoyo bore gauging. Interchangeable heads allow an operator to move between bore sizes without changing the complete instrument, while using the same display, data output and familiar handling.
For best accuracy, keep the measuring head square to the bore axis, measure at more than one depth to check for taper or ovality, and allow the workpiece and instrument to reach the same temperature before measuring.
Each head must be set against a known diameter using an appropriate setting ring. Tell our team which bore sizes you measure most frequently and we can confirm the included heads and recommend the required setting rings. General Tech can also arrange calibration.

Frequently Asked Questions
What range does the Mitutoyo 468-979 set cover?
The Mitutoyo 468-979 covers 2-4" using interchangeable measuring heads.
How does the interchangeable-head system work?
Different heads can be fitted to the same digital body to measure different bore sizes, allowing one instrument set to cover multiple ranges.
Is the Mitutoyo 468-979 suitable for coolant areas?
The listing specifies IP65 protection, making the set suitable for appropriate shop-floor environments where dust and coolant may be present.
Why choose a set instead of individual bore micrometers?
An interchangeable-head set can cover multiple bore ranges while using one digital body, helping reduce the number of separate instruments required and simplifying storage.
Should I choose the 468-979 or the 468-980?
The 468-979 covers 2-4", while the 468-980 covers 4-8". Select the set according to the bore sizes you need to measure.
Do I need setting rings for the interchangeable heads?
Yes. Each head must be set against a known diameter using the appropriate setting ring. Contact our team to confirm the required rings for your measuring ranges.
How should I care for the instrument?
Wipe the measuring faces clean after use and store the set in its case away from excessive heat, humidity and coolant. Remove the battery if the instrument will be stored for an extended period. Regular calibration helps maintain reliable measurements.
Can the instrument be calibrated?
Yes. General Tech Saudi provides calibration services for dimensional measuring instruments. Ask our team about calibration when you order.
Can you supply other Mitutoyo instruments in the same order?
Yes. General Tech can supply a wide range of Mitutoyo micrometers, bore gauges, calipers and indicators. Contact the team for a combined quotation.
Is genuine Mitutoyo available in Saudi Arabia?
Yes. General Tech is an authorised Mitutoyo distributor. Contact the team for current pricing, availability and lead time.
