Product Description
The Mitutoyo 568-928 is an interchangeable-head Borematic set designed for precision measurement of small internal bores from .275–.5" (6.985–12.7 mm). It provides coverage across three ranges while using one digital 568-015 display unit, making it suitable for inspection teams that measure different small bore sizes during the same workflow.
The set includes three interchangeable heads covering .275–.35", .35–.425" and .425–.5". The included 954595 adaptor supports head installation, while setting rings 177-179 and 177-283 are supplied for the applicable ranges.
The three-point measuring system uses self-centring TiN-coated contact points to help provide repeatable internal diameter readings. The contacts can reach close to the bottom of blind holes, which is useful for components such as fuel-injector bodies, hydraulic valve bores, small bushings and precision guide holes.
The 568-015 display unit provides .00005" (0.001 mm) resolution and an 8.5 mm LCD with a 330° rotatable display. Inch and metric units can be switched as required. Its electrostatic capacitance ABSOLUTE encoder helps retain the origin without over-speed errors.
The gauge also supports ZERO/ABS, 2-point preset, GO/NO-GO judgement with user-set upper and lower limits, data hold, error alarm, low-battery alert and function lock. Digimatic SPC output allows measurement data to be transferred to compatible data-collection and SPC systems.
Because the heads are interchangeable, the gauge must be mastered on the appropriate setting ring after changing to a different head. This makes the 568-928 suitable when multiple small-bore ranges need to be covered with one shared display unit.
Key Benefits
-
Covers .275–.5" (6.985–12.7 mm) with three interchangeable measuring heads.
-
Uses one 568-015 ABSOLUTE digital display unit across the three head ranges.
-
Three-point self-centring measurement helps provide consistent bore readings.
-
.00005" (0.001 mm) resolution for detailed small-bore inspection.
-
TiN-coated measuring contacts reach close to the bottom of blind holes.
-
330° rotatable LCD helps improve viewing from different inspection positions.
-
GO/NO-GO judgement supports user-defined upper and lower tolerance limits.
-
SPC output supports digital measurement-data collection.
-
Included setting rings help establish the reference for the supplied heads.
-
Interchangeable heads provide coverage across multiple small-bore sizes without requiring a separate display for each range.
Who This Product Is Best For
The Mitutoyo 568-928 is suitable for precision machine shops, fuel-system repair workshops, hydraulic service teams, aerospace maintenance and repair operations, and quality-control inspectors across Saudi Arabia and the GCC.
Typical applications include fuel-injector bodies, hydraulic valve spool bores, small bushings, guide holes and other precision components with small internal diameters.
It is particularly useful when one inspection station needs to measure several small-bore sizes within the .275–.5" range.
How to Use / How It Works
-
Select the head: Choose the interchangeable head that covers the required bore range: .275–.35", .35–.425" or .425–.5".
-
Attach the head: Fit the selected head to the 568-015 display unit using the supplied adaptor.
-
Master the gauge: Place the selected head in the matching setting ring, press the appropriate ZERO/ABS or preset function and establish the reference using the certified ring size.
-
Measure the bore: Operate the snap-open lever, insert the head into the bore and release it so the three contact points self-centre.
-
Check the result: Use the display to read the internal diameter and, where required, check multiple positions for dimensional variation.
-
Judge and record: Use GO/NO-GO limits for tolerance inspection, hold the reading or transfer the measurement through Digimatic SPC connectivity.
-
Re-master after changing heads: When switching to another measuring head, use its matching setting ring to establish the correct reference before taking measurements.
Frequently Asked Questions
What bore range does the Mitutoyo 568-928 cover?
The set covers internal diameters from .275–.5" (6.985–12.7 mm) using three interchangeable heads.
Which heads are included with the 568-928?
The set includes heads covering .275–.35", .35–.425" and .425–.5".
What display unit is included?
The Mitutoyo 568-928 uses the 568-015 digital ABSOLUTE display unit.
Are setting rings included?
Yes. The set includes setting rings 177-179 and 177-283 for the applicable measuring ranges.
Does the 568-928 use three-point measurement?
Yes. The interchangeable heads use three-point contact with a self-centring measuring system.
Do I need to re-master the gauge when changing heads?
Yes. After installing a different head, use the appropriate matching setting ring to establish the reference before measurement.
Can the 568-928 measure blind holes?
Yes. The TiN-coated measuring contacts are designed to reach close to the bottom of blind holes.
Can measurement data be sent to SPC software?
Yes. The 568-015 display unit supports Digimatic SPC output and can be connected using SPC cables 905338 or 905409, USB Input Tool Direct 06ADV380F, or compatible U-WAVE-T connectivity.
What is the difference between the 568-928 and 568-965?
The 568-928 is an interchangeable-head set that uses one shared display unit. The 568-965 is a complete-unit set where individual gauge units are provided for the applicable measuring ranges.
Which interchangeable-head set covers larger bores?
The Mitutoyo 568-928 covers .275–.5". For larger bores from .5–1", the Mitutoyo 568-929 is the relevant interchangeable-head set.
