The Etalon .600" to .800" Bore Micrometers with Calibration Ring are high-quality tools used for precise measurements in CNC, metalworking, and manufacturing industries. Made in Switzerland, these micrometers feature a mechanical reading with resolution as fine as 0.00010 inches. Perfect for metalworking inspection and measurement, these bore micrometers from Lufkin provide accurate and reliable measurements for your specific needs.

These two Etalon bore micrometers are in pretty good condition. The spindles rotate freely and friction symbols work as they should.  The numbers and markings are easy to read. There is some engraving from the previous owner.  They come with a calibration ring. I will pack it very carefully so that nothing is damaged in transit.
