Mitutoyo 103-927-10 Outside Micrometer Set 3 Pc

Product Description

The MITUTOYO 103-927-10 is a 3-piece mechanical outside micrometer set covering a measurement range of 0 to 75 mm in three incremental spans. Each micrometer features a ratchet stop thimble for consistent measuring pressure and solid carbide measuring faces for long-term wear resistance. The baked enamel finish protects the frame in shop environments. Graduation is 0.01 mm with an accuracy of 2 micrometers. This set is intended for use by machinists, tool-and-die technicians, metrology lab personnel, and precision manufacturing inspectors who require reliable outside diameter and thickness measurements.

This micrometer set is suited for precision measurement tasks in manufacturing, quality control, and machine shop environments. The three-piece configuration covers 0 to 25 mm, 25 to 50 mm, and 50 to 75 mm ranges, making it practical for a wide variety of workpiece sizes encountered in general machining and inspection work. Each unit ships with a certificate of inspection confirming factory calibration, and setting standards are included for the 25 mm and 50 mm ranges upward, supporting field re-verification of calibration between formal calibration cycles.

Key Features

• 3-piece set covering 0 to 75 mm in 25 mm increments
• Ratchet stop thimble delivers repeatable, consistent measuring force
• Solid carbide measuring faces resist wear on hardened and abrasive workpiece materials
• 0.01 mm graduation with 2-micrometer accuracy
• Baked enamel frame finish for shop durability
• Includes certificate of inspection, setting standards (from 25 mm upward), key, and storage box

Compatibility

Designed as a general-purpose mechanical outside micrometer set for precision measurement of external dimensions on cylindrical, flat, and shaped workpieces in standard shop and quality control applications.

Installation Notes

Outside micrometers require no installation but should be zeroed and verified against the included setting standards before use following the manufacturer's procedure. Store micrometers in the provided case away from direct heat, coolant mist, and magnetic fields that can affect calibration. Clean spindle threads and measuring faces with a lint-free cloth before and after each use. Calibration verification should be performed at regular intervals in accordance with your facility's quality management procedures.
