Mitutoyo 122-127-10 Blade Micrometer 2-3" | KSA
PRODUCT SUMMARY
The Mitutoyo 122-127-10 blade micrometer measures groove and keyway diameters from 2–3" with .0001" graduation and ±.00015" accuracy. Its Type A hardened steel blade and non-rotating spindle provide controlled access to narrow features that standard micrometers cannot easily reach.
PRODUCT DESCRIPTION
The Mitutoyo 122-127-10 Series 122 blade micrometer is designed for measuring groove diameters, keyways, snap-ring grooves, spline roots and other narrow features where a conventional micrometer cannot easily reach. Its 2–3" (50.8–76.2 mm) measuring range makes it suitable for dimensional inspection of shafts, pins and precision-machined components.
The micrometer uses a Type A hardened steel blade measuring .030" (0.75 mm) thick, allowing the measuring faces to enter narrow grooves and slots. Its non-rotating spindle helps maintain blade alignment as the spindle closes, reducing twisting across the groove during measurement.
A ratchet stop provides a constant 3–8 N measuring force, helping produce consistent contact during repeated measurements. The instrument provides ±.00015" accuracy, .0001" graduation and .00012" measuring-face parallelism for precision inch-based dimensional inspection.
The spindle and blade arrangement is suited to applications where a conventional round anvil or rotating spindle may have limited access. The satin chrome thimble and sleeve help improve scale visibility under workshop lighting, while the analog mechanical design allows direct reading without electronic conversion.
The micrometer is designed for inch measurements, making it suitable for components and engineering drawings dimensioned in inches. A standard bar is supplied for zero-setting and reference checking, since the measuring range begins at 2". The main unit weighs approximately 360 g and is supplied in a fitted protective case.
For larger measurements, the Mitutoyo 122-128-10 covers 3–4" with the Series 122 blade-micrometer design.

WHO THIS PRODUCT IS BEST FOR
The Mitutoyo 122-127-10 is suitable for CNC turning shops, automotive component manufacturers, pump and valve repair workshops, maintenance teams and quality-control departments working with groove and keyway features in the 2–3" range.
It is useful for inspecting shaft grooves, keyways, snap-ring grooves, spline roots and other narrow machined features. Quality inspectors can use it for first-off and final dimensional checks, while machinists can verify features during production and maintenance technicians can inspect worn shafts before repair or rebuilding.
This model is particularly suitable for workshops working with inch-dimensioned drawings and components where recessed groove measurements require a blade-style micrometer.
HOW TO USE / HOW IT WORKS
-
Clean the blade and spindle measuring surfaces before measurement.
-
Check the micrometer against the supplied standard bar and verify the reference setting.
-
Open the micrometer slightly wider than the groove or keyway.
-
Position the blade and spindle squarely inside the feature.
-
Turn the ratchet stop until the measuring force is applied consistently.
-
Read the sleeve and thimble scale in .0001" increments.
-
Record the measurement while maintaining correct alignment with the feature.
FREQUENTLY ASKED QUESTIONS
What is the Mitutoyo 122-127-10 blade micrometer used for?
It is designed for measuring groove diameters, keyways, snap-ring grooves and other narrow features from 2–3" (50.8–76.2 mm).
What is the accuracy of the Mitutoyo 122-127-10?
The 122-127-10 provides ±.00015" accuracy with a .0001" graduation. The specified measuring-face parallelism is .00012".
What type of blade does the 122-127-10 use?
It uses a Type A hardened steel blade with a thickness of .030" (0.75 mm).
Why does the 122-127-10 use a non-rotating spindle?
The non-rotating spindle helps keep the blade aligned with the groove and reduces twisting during measurement.
What is the measuring force?
The ratchet stop provides a constant measuring force of approximately 3–8 N.
Is a standard bar included?
Yes. A standard bar is included for zero-setting and reference checking because the measuring range begins at 2".
What is the difference between the 122-127-10 and 122-128-10?
The 122-127-10 covers 2–3", while the 122-128-10 covers 3–4". Both use the Series 122 blade-micrometer design.
What is the difference between Mitutoyo 122-127 and 122-127-10?
Both references are associated with the Series 122 2–3" blade micrometer. The supplied product data identifies 122-127-10 as the order number for this listing. If both references appear in your catalogue or inventory, confirm the exact order number before creating a duplicate Shopify product page.
