Groove Micrometers The Groove Micrometer is a specialized precision measuring instrument designed for accurate measurement of groove widths, groove depths, inside diameters, outside diameters, bores, tubes, and recessed features. Its unique flange design allows precise access to grooves and narrow measuring areas that are difficult to measure using standard micrometers. The instrument features dual graduations for both inside and outside measurements, making it highly versatile for multiple inspection applications. The non-rotating spindle and two-directional ratchet stop ensure constant measuring force and repeatable measurement results. Widely used in precision engineering, manufacturing, automotive, aerospace, machining, quality control, and metrology applications, the Groove Micrometer provides reliable measurements in demanding industrial environments.
