Starrett Inside Hole Micrometers
Find the inside diameter of cylinders and rings. These micrometers have a plain thimble, which relies on operator feel for accurate measurements.
124 series have solid steel extensions that attach at one end of the micrometer head.
Collars (sold separately) extend a micrometer’s measuring range. Handles (sold separately) screw into a micrometer head to extends its reach for measuring deep holes.
