Mitutoyo 122-102-10 | Blade Micrometer | Series 122 | Graduation 0.01mm | Accuracy ± 0.003mm | Range 25 to 50mm

Part Number: Mitutoyo 122-102-10

The Mitutoyo 122-102-10 blade micrometer features blade-shaped anvil and spindle faces with a 0.75 mm hardened steel blade that reaches into grooves, keyways and narrow slots where a flat-faced micrometer cannot. It measures 25–50 mm with 0.01 mm graduation and ±3 μm accuracy. Request a quote in under a minute - call or WhatsApp +965 9807 4888.

The 122-102-10 is a Series 122 blade micrometer specified with 0.01 mm graduation and ±3 μm accuracy, making it suitable for buyers who need to match a purchase-order requirement based on graduation and accuracy.

A conventional micrometer's round measuring faces can be too wide to sit inside a groove, causing the measurement to be taken from the shoulder rather than the groove floor. The thin blade faces on the anvil and spindle reach directly into the feature. Because the spindle does not rotate, the blades remain aligned with the slot as they close.

The 25–50 mm range suits keyways, O-ring and circlip grooves, splines and narrow slots on small shafts. It is suitable for machine shops, power and desalination plant maintenance teams, oil and gas service contractors and precision inspection applications in Kuwait.

For best results, allow the Mitutoyo 122-102-10 and the part to reach the same temperature before measuring. Steel expands about 11.5 μm per metre per °C, so at 50 mm, a 10 °C temperature difference can shift the reading by around 5.8 μm.

For larger groove diameters, the Mitutoyo 122-103-10 covers the 50–75 mm range.

Key Benefits

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

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

• Stated accuracy — ±3 μm across the measuring range.

• Durable blade — 0.75 mm hardened steel construction for long service life.

• Consistent force — ratchet stop helps maintain consistent measuring pressure.

• Trusted Mitutoyo design — Series 122 mechanical blade micrometer for precision inspection work.

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

Who This Product Is Best For

• Machinists measuring keyways.

• 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 faces instead of a conventional flat-anvil outside micrometer.

How to Use

1. Clean the blades and check zero with a setting standard of known size.

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

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

4. Read the sleeve and thimble graduations.

Frequently Asked Questions

What range does the Mitutoyo 122-102-10 blade micrometer measure?

It measures 25–50 mm with 0.01 mm graduation.

What is a blade micrometer used for?

It is used to measure 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. This helps prevent the blade from twisting out of the groove and reduces the risk of scoring the part.

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

Hardened steel is suitable for most general measurement work. Carbide-tipped blades offer greater resistance to abrasion and chipping, which can be useful on hard or abrasive materials and in heavy-use inspection environments.

Which blade micrometer should I choose if my groove is outside 25–50 mm?

Choose a range that brackets the groove diameter. The Mitutoyo 122-101-10 covers 0–25 mm, while the Mitutoyo 122-103-10 covers 50–75 mm. Thinner 0.4 mm blades can be suitable for narrower grooves than 0.75 mm blades.

Can it be recalibrated?

Yes. The Mitutoyo 122-102-10 can be periodically recalibrated through an ISO/IEC 17025-accredited calibration service to maintain measurement traceability.
