Mitutoyo 122-127 Blade Micrometer, Hardened Steel Blade 2-3", 0.75mm Blade

Part Number: Mitutoyo 122-127

The Mitutoyo 122-127 blade micrometer features blade-shaped anvil and spindle faces with a 0.75 mm hardened steel blade, allowing it to reach grooves, keyways and slots that conventional flat-faced micrometers cannot access. It measures 2"–3" (50.8–76.2 mm) with 0.0001" graduation and ±0.00015" accuracy.

Flat micrometer faces can be too wide for grooves, keyways and narrow slots, causing measurements to be taken from the shoulder rather than the feature itself. The Mitutoyo 122-127 uses blade-shaped anvil and spindle faces that reach the bottom of the groove for direct measurement.

The non-rotating spindle keeps the blade parallel to the slot as it closes, while the 0.75 mm hardened steel blade provides durability for regular workshop use. The 2"–3" range is suitable for groove diameters on pump and motor shafts, seal grooves and keyways on medium drive shafts.

Keep the contact faces clean and store the Mitutoyo 122-127 in its case between jobs. For precision measurements in hot Kuwait workshops, allow the workpiece and micrometer to reach a suitable temperature before taking a final reading.

Who This Product Is Best For

• Machinists measuring groove diameters on pump and motor shafts

• Pump, motor and gearbox rebuild workshops checking seal and circlip grooves

• QC inspectors verifying groove diameters against engineering drawings

• Maintenance teams requiring a battery-free precision measuring tool

• Buyers who need blade faces for recessed features rather than conventional flat-anvil micrometer faces

How to Use

1. Clean the measuring blades and verify the micrometer's zero condition.

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 the appropriate measuring force is applied.

4. Read the sleeve and thimble graduations.

5. Record the measurement and clean the contact faces before storage.

Frequently Asked Questions

What range does the Mitutoyo 122-127 blade micrometer measure?

It measures 2"–3" (50.8–76.2 mm) with 0.0001" graduation.

What is a blade micrometer used for?

It is designed for measuring groove diameters, keyways, splines and narrow slots where conventional flat-faced micrometers cannot properly reach the feature.

Why does the Mitutoyo 122-127 have a non-rotating spindle?

The non-rotating spindle keeps the blade parallel to the slot while closing, helping maintain consistent alignment with the feature.

What is the difference between a hardened steel and carbide-tipped blade?

A hardened steel blade is suitable for general measurement applications. Carbide-tipped blades can offer greater resistance to wear in demanding or abrasive measurement environments.

Which blade micrometer should I choose if my groove is outside the 2"–3" range?

Choose a micrometer whose measuring range covers the groove diameter. The Mitutoyo 122-126 covers 1"–2", while the 122-128 covers 3"–4".

Can the Mitutoyo 122-127 be recalibrated?

Yes. The micrometer can be periodically calibrated through a qualified calibration service to help maintain measurement traceability.
