Mitutoyo 103-913-50 Outside Micrometer Set 6 Pc

Product Description

The MITUTOYO 103-913-50 is a 6-piece mechanical outside micrometer set covering a measurement range of 0 to 150 mm in 25 mm increments. Each micrometer features a ratchet stop thimble for consistent measuring force and solid carbide measuring faces for extended wear resistance. Graduation is 0.01 mm across all pieces in the set. Accuracy is 2 micrometers for the 0 to 75 mm range and 3 micrometers for the 75 to 150 mm range. The baked enamel finish provides corrosion resistance in shop environments. Machinists, tool and die technicians, and quality control inspectors use this set for precise outside dimensional measurement of workpieces, shafts, and mechanical components.

This set is suited for production floor, toolroom, and inspection applications requiring coverage across multiple measurement ranges without switching instruments. The six individual micrometers span 0-25 mm, 25-50 mm, 50-75 mm, 75-100 mm, 100-125 mm, and 125-150 mm. Each unit ships with a certificate of inspection confirming calibration at the factory. Setting standards are included for all ranges from 25 mm upward, allowing field verification and recalibration without sending units out. The set is packaged in a fitted storage box for organized bench or toolroom storage.

Key Features

• 6-piece set covers 0 to 150 mm in 25 mm range increments
• Ratchet stop thimble delivers repeatable measuring force across all pieces
• Solid carbide measuring faces resist wear on hardened and abrasive workpiece materials
• 0.01 mm graduation for precise dimensional readings
• Accuracy of 2 micrometers (0-75 mm) and 3 micrometers (75-150 mm)
• Includes certificate of inspection, setting standards from 25 mm upward, key, and storage box

Compatibility

Designed as a standalone outside micrometer set for general-purpose dimensional measurement. No specific system or instrument compatibility is required beyond standard metric measurement practices.

Installation Notes

Outside micrometers require no installation but should be handled and stored with care to preserve calibration. Before use, verify each micrometer against its included setting standard and adjust using the provided key if zero error is present. Keep measuring faces clean and free of chips or debris before and after use. Store units in the provided box when not in use to prevent damage to the measuring faces and thimble mechanisms.
