Product Overview
The Mitutoyo 122-162 Series 122 blade micrometer is designed for measuring narrow grooves, keyways, snap-ring grooves, spline roots and O-ring grooves that are difficult to access with a conventional micrometer. Its Type C carbide-tipped blade provides a 25–50 mm measuring range with 0.01 mm graduation and ±3 µm accuracy.
The 0.75 mm carbide-tipped blade provides a robust measuring profile for groove and keyway inspection. The non-rotating spindle keeps the blade aligned with the measurement feature as it closes, helping reduce twisting between the measuring faces and the workpiece.
A ratchet stop provides a controlled 3–8 N measuring force, supporting consistent measurements during repeated inspections. The satin chrome thimble and sleeve provide a clear mechanical metric scale, while the supplied standard bar allows convenient zero-setting before measurement.
The carbide-tipped blade is suited to demanding inspection environments where repeated contact can cause conventional steel measuring surfaces to wear. This makes the 122-162 useful for production inspection, machining and maintenance applications where consistent groove measurements are required.
The micrometer is supplied in a fitted protective case for storage and transport.
For larger components requiring a 50–75 mm measuring range, consider the Mitutoyo 122-103 blade micrometer.
Key Benefits
-
Groove and keyway access: The blade-shaped measuring surfaces provide access to narrow features within the 25–50 mm range.
-
Precise dimensional inspection: ±3 µm accuracy and 0.01 mm graduation support detailed measurement work.
-
0.75 mm carbide-tipped blade: Type C blade construction provides a robust measuring profile with enhanced wear resistance.
-
Non-rotating spindle: Keeps the blade aligned with the groove and reduces twisting during measurement.
-
Consistent measuring force: The ratchet stop provides a controlled 3–8 N measuring force.
-
Clear mechanical scale: Satin chrome thimble and sleeve provide a readable metric measurement scale.
-
Convenient zero-setting: The supplied standard bar allows the micrometer to be checked and zero-set before measurement.
-
Protective storage: Supplied in a fitted case for storage and transport.

Who This Product Is Best For
The Mitutoyo 122-162 is suitable for CNC turning and machining shops, automotive component manufacturers, pump and valve repair workshops, maintenance departments and quality-control teams working with components containing grooves or keyways.
It can be used by quality inspectors checking first-off components, machinists verifying dimensions during production and maintenance engineers measuring shafts and other components before repair or replacement.
The 25–50 mm range makes the 122-162 suitable for metric drawings and components where the measurement feature is located inside a narrow slot or groove. Its 0.75 mm carbide-tipped blade provides a more robust blade profile than the thinner 0.4 mm blade used on the 122-142.
How to Use
-
Clean the blade faces and the measurement feature before taking a reading.
-
Check the micrometer against the supplied standard bar and confirm the zero setting.
-
Open the micrometer slightly wider than the feature being measured.
-
Position the blade-shaped measuring faces squarely inside the groove or keyway.
-
Turn the ratchet stop until it clicks two or three times to apply the controlled measuring force.
-
Read the sleeve and thimble scale at the 0.01 mm graduation.
-
Record the measurement while the micrometer remains correctly positioned on the feature.
-
Clean the measuring faces after use and store the instrument in its fitted case.
Frequently Asked Questions
What is the Mitutoyo 122-162 blade micrometer used for?
The 122-162 is designed for measuring groove diameters, keyways, snap-ring grooves, spline roots, O-ring grooves and other narrow features within its 25–50 mm measuring range.
How accurate is the Mitutoyo 122-162?
The 122-162 has ±3 µm accuracy and a 0.01 mm graduation. The specified parallelism of the measuring faces is 3 µm.
Why does the Mitutoyo 122-162 use a non-rotating spindle?
The non-rotating spindle keeps the blade aligned with the groove as the spindle closes. This helps reduce twisting between the blade and workpiece and supports consistent measurements.
What type of blade does the Mitutoyo 122-162 have?
The 122-162 uses a Type C carbide-tipped blade with a 0.75 mm blade thickness. This provides a more robust blade profile than the 0.4 mm blade used on the 122-142.
Which 25–50 mm Series 122 blade micrometer should I choose?
The choice depends on the groove geometry, blade thickness and application. The 122-162 uses a 0.75 mm carbide-tipped blade. The 122-142 uses a thinner 0.4 mm carbide-tipped blade, while the 122-112 uses a 0.4 mm hardened-steel blade and the 122-102 uses a 0.75 mm hardened-steel blade.
Is a setting standard included with the Mitutoyo 122-162?
Yes. A standard bar is supplied for zero-setting because the measuring range begins at 25 mm rather than zero. The micrometer is also supplied in a fitted protective case.
