Mitutoyo 112-238 Mechanical Point Micrometer 1 to 2 Inch

Product Description

The MITUTOYO 112-238 is a mechanical point micrometer designed for precise measurement of 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 an accuracy rating of 0.00015 inches. The 30-degree point angle on both the spindle and anvil allows access to narrow recesses and chamfered features. The ratchet stop mechanism provides consistent measuring force, reducing operator-to-operator variation. The 49mm throat depth extends reach into deeper workpiece profiles. This tool is used by machinists, toolmakers, and quality control technicians working to tight tolerances in precision manufacturing environments.

This micrometer is suited for inspection and layout work where a conventional micrometer cannot contact the measurement surface. The 18mm head diameter and 6.35mm spindle diameter keep the instrument compact enough for confined measurement locations. The 0.5039-inch point length provides the clearance needed to seat the points cleanly in grooves or on steps. It is equally applicable on production floors and in tool rooms where dimensional verification of turned, milled, or ground components is required. TUV certification supports use in calibrated inspection environments.

Key Features

• 30-degree point angle on both spindle and anvil for groove and step access
• Ratchet stop ensures consistent, repeatable measuring force
• 49mm throat depth for reach into deep workpiece profiles
• TUV certified for use in calibrated inspection applications
• Battery-included SR44 cell powers the readout display

Compatibility

Designed as a mechanical point micrometer for measuring grooves, steps, and similar recessed or narrow features on machined workpieces requiring a 1 to 2 inch measurement range.

Installation Notes

Handled and used by machinists and quality control technicians familiar with precision measuring instruments. Before use, clean the anvil and spindle points and verify zero calibration at the 1-inch setting using the supplied standard or a traceable gauge block. Do not overtighten the thimble — always engage the ratchet stop to apply measuring force. Store in the provided case to protect the carbide or hardened steel points from damage.
