Mitutoyo 122-135-10 Blade Micrometer 1 Inch Mechanical

Product Description

The MITUTOYO 122-135-10 is a mechanical blade micrometer designed for measuring narrow grooves, slots, and recessed features that standard anvil micrometers cannot reach. It measures up to 1 inch with a graduation of 0.0001 inches and an accuracy of 0.000150 inches. The blades are 0.0157 inches thick and 3.00 mm deep, allowing access into tight geometry. A ratchet thimble provides consistent measuring force for repeatable readings. The non-rotating spindle prevents the workpiece from turning during measurement. The instrument is rated IP54 for protection against dust and splash, making it suitable for light shop-floor use. Precision machinists, toolmakers, and quality control technicians are the primary users of this instrument.

The 122-135-10 is suited for dimensional inspection work in machine shops, manufacturing facilities, and tool rooms where narrow internal features require precise measurement. Typical applications include keyway width verification, thin-wall groove inspection, and slot depth profiling on machined components. The blade design allows the micrometer to seat flush into features where a conventional flat anvil would not make proper contact. The included plastic case protects the instrument during storage and transport between job sites or inspection stations.

Key Features

• Blade thickness of 0.0157 inches (0.40 mm) for access into narrow grooves and slots
• Graduation of 0.0001 inches with 0.000150 inches accuracy
• Non-rotating spindle prevents workpiece displacement during measurement
• Ratchet thimble delivers consistent, repeatable measuring force
• IP54-rated for dust and splash resistance in shop-floor environments
• Data output capability for integration with SPC or data collection systems
• Includes plastic storage and transport case with SR44 battery

Compatibility

Designed as a standalone precision measurement instrument compatible with standard SPC data collection systems that accept micrometer data output. No specific replacement part compatibility is stated for this instrument.

Installation Notes

This instrument requires no installation. Calibration and zeroing should be performed before use according to standard metrology procedures. Store in the provided plastic case when not in use to protect the blades and measuring faces from damage. Do not over-tighten or force the thimble beyond the ratchet stop, as this can affect accuracy and blade alignment.
