Etalon Metric 20-40mm INTALOMETER Intrimik Bore Micrometer Set.
These micrometers can measure a bore diameter all the way down to the bottom of the bore (provided it will reach the bottom).
A 6" extension is provided for holes up to 8" or 9" deep.
Includes:
- 20-25 mm bore micrometer (.7874" to .9843")
- 25-30 mm bore micrometer (.9843" to 1.1811")
- 30-35 mm bore micrometer (1.1811" to 1.3780")
- 35-40 mm bore micrometer (1.3780" to 1.5748")
- 6 " extension (new in package)
- adjustment wrench
- 25 mm setting ring
The two smaller micrometers checked pretty close when inserted in the included 25 mm setting ring. Adjust if necessary with the wrench.
I checked the two larger micrometers with 1.200" and 1.400" set rings of mine. They were very close (the rings however, were rusty in spots and the last time they were checked for accuracy was probably in the last century).
I'd highly recommend getting a 35 mm setting ring (or a 1.1811" to 1.3780" ring for the 30-35 mm micrometer and a 1.378" to 1.5748" ring for the 35-40 mm micrometer).
Nice Condition! The box has some signs of wear and some engravings. See images.
Note that these micrometers have been in storage for some time and may require some cleaning and perhaps a drop or two of clock oil or other light instrument oil.
Currently, returning the micrometers to their smallest size requires backing off the spindle then a firm push on the arms.
