Mitutoyo 112-190 Point Micrometer 1 to 2 Inch

Product Description

The MITUTOYO 112-190 is a mechanical point micrometer designed for measuring grooves, steps, and similar features that standard flat-anvil micrometers cannot reach. It covers a measurement range of 1 to 2 inches with a resolution of 0.00005 inches and 0.001 inch graduation, delivering accuracy to within 0.00015 inches. The 49mm throat depth allows access into recessed workpiece geometry, while the ratchet stop mechanism provides consistent measuring force for repeatable readings. The 15-degree point angle on both the spindle and anvil allows entry into narrow slots and grooves. This tool is sized for use by machinists and precision measurement technicians in tool-and-die, production, and metrology environments.

The 112-190 is suited for dimensional inspection tasks where narrow-contact measurement is required, such as checking groove widths, shoulder recesses, keyways, and similar workpiece features. The 18mm head diameter keeps the body compact near the measurement zone, and the 6.35mm spindle diameter provides rigidity without obstructing access. This micrometer is appropriate for both shop-floor and inspection-room use in manufacturing and fabrication settings.

Compatibility

Designed as a direct-use precision measuring instrument for grooves, steps, and similar recessed features in the 1 to 2 inch measurement range. No specific system compatibility noted in available data.

Installation Notes

Point micrometers require no installation but should be handled and stored by a qualified metrologist or machinist. Before use, clean the measuring faces and verify calibration against a known standard. Protect the precision ground points from impact and avoid storing in contact with other tools. Handle with care to preserve point geometry and measurement accuracy.
