Measuring Blind Depths, Slots & Steps Accurately
Depth micrometers are essential when a machined feature must sit at an exact depth below a reference face - blind holes, counterbores, keyway depths, slots and recessed steps. The flat hardened base sits on the reference surface while the rod extends into the feature, giving a direct 0.01mm reading of true depth.
Interchangeable rods allow a single instrument body to cover multiple ranges, keeping the QC kit compact and economical. Mitutoyo, Insize and Starrett depth micrometers feature a smooth ratchet mechanism for consistent contact pressure and a lock screw for securing readings, making them dependable tools for both machine setup and final inspection.
