The Mitutoyo 103-218 Mechanical Outside Micrometer is built for accurate outside measurements on machine shop parts, components, and other precision workpieces. With a 0.0001" graduation and a maximum measurement of 4", it provides the fine measurement resolution needed for dimensional inspection.
The micrometer features a hammertone, baked enamel finished frame for a durable shop ready design. A ratchet stop helps produce consistent, repeatable readings by maintaining controlled measuring force. The unit also comes with a standard bar for setup and reference needs.
The Mitutoyo 103-218 outside micrometer has a 3 to 4" measuring range and a maximum metric measurement of 101.60 mm. Its carbide measuring surfaces support dependable contact with workpieces during routine inspection and machining applications.
0.0001" Graduation
A 0.0001" graduation provides fine measurement resolution for precision inspection work. The clear mechanical design makes it suitable for machinists, inspectors, and quality control personnel.
3 to 4" Measuring Range
The measuring range covers outside dimensions from 3" through 4", with a maximum measurement of 4.0000" or 101.60 mm.
Ratchet Stop
The ratchet stop helps maintain consistent measuring pressure from one reading to the next. Repeatable pressure can help improve consistency during inspection tasks.
Carbide Measuring Surfaces
Carbide measuring surfaces provide durable contact points for regular measurement work in machine shop environments.
Durable Enamel Finish
The hammertone, baked enamel finished frame provides a durable exterior suitable for everyday shop use.
Standard Bar Included
