Mitutoyo 128-106 | Depth Micrometer | 0-1", 4" base
Part No. 128-106 | Mitutoyo Series 128
Product Description
The Mitutoyo 128-106 is a mechanical depth micrometer designed for shallow depth measurements from 0 to 1 inch. It features a fixed ø4 mm measuring rod and a 4 × .63 inch hardened, ground and micro-lapped base, providing a stable reference for checking counterbores, pockets, slots, keyways, recesses and step heights.
The wide 4-inch base provides broad support across larger openings and can help maintain stable positioning on housings, castings, flanges and other components with a larger reference area. The base has 2 µm flatness, while the micrometer head provides ±.00012 inch accuracy with .001 inch graduation.
A ratchet stop helps maintain consistent measuring force for repeatable readings. The measuring-rod clamp can secure the measurement when the tool needs to be lifted or repositioned before reading. Since the ø4 mm measuring rod is fixed, measurements within the 0–1 inch range can be taken without changing rods.
For applications where a more compact base is preferred, see the Mitutoyo 128-105 with its 2.5 × .63 inch base. For deeper measurements, the Mitutoyo 129-129 provides an interchangeable-rod configuration for a greater measuring range.

Who This Product Is Best For
The Mitutoyo 128-106 is suitable for machinists, toolmakers, production inspectors and quality-control teams measuring shallow features up to 1 inch. Its wider 4-inch base is useful when a broad reference surface is preferred across larger openings on housings, castings, flanges and machined components.
How to Use
-
Check the micrometer zero with the base resting flat and the measuring rod positioned against the reference surface.
-
Place the 4 × .63 inch base squarely across the opening or feature being measured.
-
Hold the base firmly against the reference surface.
-
Turn the thimble until the measuring rod contacts the bottom of the feature.
-
Finish the measurement using the ratchet stop to apply consistent measuring force.
-
Lock the measuring rod if the reading needs to be secured before reading.
-
Read the sleeve and thimble graduation and record the measured depth.
Frequently Asked Questions
What is the Mitutoyo 128-106 used for?
It is designed for shallow depth measurements from 0 to 1 inch, including counterbores, slots, pockets, keyways, steps and recesses.
How accurate is the Mitutoyo 128-106?
The micrometer head has a specified accuracy of ±.00012 inch and a graduation of .001 inch.
Does the 128-106 use an interchangeable measuring rod?
No. The 128-106 uses a fixed ø4 mm measuring rod covering the 0–1 inch range. This allows routine measurements without changing rods.
What is the difference between the 128-106 and 128-105?
Both are Series 128 fixed-rod depth micrometers with a 0–1 inch range. The 128-106 has a larger 4 × .63 inch base, while the 128-105 has a more compact 2.5 × .63 inch base.
When should I choose the 128-106 instead of the 128-105?
The 128-106 is the wider-base option and may be preferred when greater base coverage is useful across a larger opening. The 128-105 is more compact for smaller or space-constrained measurement areas.
When should I choose an interchangeable-rod depth micrometer?
An interchangeable-rod model is useful when measurements extend beyond the fixed 0–1 inch range or when multiple measuring ranges are required. The Mitutoyo 129-129 provides an interchangeable-rod configuration for deeper measurements.
