This mechanical inside micrometer is designed for precise internal diameter measurements, featuring a highly stable three-point self-centering action. Its unique design allows for accurate measurements closer to the bottom of blind bores, and an optional extension rod can be used for deep hole applications. Key components such as the contact points and cone are crafted from durable alloy tool steel.
