This Internal Groove Micrometer is designed to measure the width and location of grooves cut into bore walls.
It offers the following features:
• Two-directional ratchet stop
A non-digital tubular Mitutoyo micrometer equipped with concentric, disc-shaped anvils for making measurements inside holes, such as width, depth and location of grooves and projections. Separate graduations for inside and outside measurements avoid need for corrections for anvil thickness. A ratchet stop guarantees repeatable measurement.
