Mitutoyo 122-141 Blade Micrometer, Carbide-Tipped Blade 0-25mm, 0.4mm Blade

Part Number: Mitutoyo 122-141

The Mitutoyo 122-141 blade micrometer features blade-shaped anvil and spindle faces with a 0.4 mm carbide-tipped blade designed to reach grooves, keyways and narrow slots that standard flat-faced micrometers cannot access. It measures from 0–25 mm with 0.01 mm graduation. Request a quote in under a minute - call or WhatsApp +965 9807 4888.

Flat micrometer faces can be too wide for grooves, keyways and narrow slots, causing the measurement to land on the shoulder instead of the feature itself. The Mitutoyo 122-141 solves this with blade-shaped anvil and spindle faces that reach the bottom of the groove.

Its non-rotating spindle keeps the blade parallel to the slot as it closes, helping prevent twisting or scoring of the part. The 0.4 mm carbide-tipped blade provides improved resistance to wear and chipping when measuring hard or abrasive materials.

With a 0–25 mm measuring range and 0.01 mm graduation, the Mitutoyo 122-141 is suitable for measuring keyways, O-ring and circlip grooves, splines and narrow slots on small shafts. It is also suitable for QC inspection during shaft and seal measurement.

Keep the contact faces clean and store the Mitutoyo 122-141 in its case between jobs. In hot workshop environments, allow the workpiece and micrometer to reach the same temperature before taking a final measurement. At 25 mm, a 10 °C temperature difference can change a steel workpiece by approximately 2.9 μm.

For larger groove diameters, the Mitutoyo 122-142 covers the 25–50 mm range. For general steel-part measurement, the Mitutoyo 122-111 uses a hardened steel blade.

Key Benefits

• 0.01 mm graduation — Provides a clear analogue reading without batteries.

• Durable blade — Carbide-tipped blade provides resistance to abrasion and wear.

• Consistent force — Ratchet stop helps maintain consistent measuring pressure between operators.

• Trusted brand — Mitutoyo Series 122 mechanical blade micrometer for precision inspection applications.

• Reaches narrow features — Blade faces measure groove floors, keyways and slots directly.

• Non-rotating spindle — Keeps the blade aligned with the slot and helps prevent twisting against the part.

Who This Product Is Best For

• Machinists measuring keyways and narrow slots.

• Pump, motor and gearbox rebuild shops checking seal and circlip grooves.

• QC inspectors verifying groove diameters against engineering drawings.

• Maintenance teams looking for a battery-free precision measuring tool.

• Buyers who need blade-shaped measuring faces rather than a conventional flat-anvil outside micrometer.

How to Use

1. Clean the blade faces and check the micrometer zero.

2. Align the blades with the groove or keyway so they sit squarely against the feature.

3. Close the spindle gently using the ratchet stop until it clicks.

4. Read the sleeve and thimble graduations.

5. For critical measurements, allow both the part and micrometer to reach the same temperature before taking the final reading.

Frequently Asked Questions

What range does the Mitutoyo 122-141 blade micrometer measure?

It measures from 0–25 mm with 0.01 mm graduation.

What is a blade micrometer used for?

It is used for measuring groove diameters, keyways, splines and narrow slots where a conventional flat-faced micrometer cannot reach the feature.

Why is the spindle non-rotating?

The non-rotating spindle keeps the blade parallel to the slot while closing, helping prevent the blade from twisting out of the groove or scoring the part.

Hardened steel or carbide-tipped blade: which do I need?

A hardened steel blade is suitable for general measurement work. The carbide-tipped blade on the Mitutoyo 122-141 provides greater resistance to abrasion and wear when working with hard or abrasive materials.

Which blade micrometer should I choose if my groove is outside 0–25 mm?

Choose a measuring range that brackets the groove diameter. The Mitutoyo 122-142 covers 25–50 mm. The 0.4 mm blade is also suited to narrower grooves than thicker 0.75 mm blade designs.

Can the Mitutoyo 122-141 be recalibrated?

Yes. It can be periodically recalibrated through an ISO/IEC 17025-accredited calibration service to maintain measurement traceability.
