Blade Micrometers – Precision Tools for Narrow Groove and Small Feature Measurements
Blade micrometers are specialized measuring tools designed to measure narrow grooves, small slots, keyways, and recessed features that standard micrometers cannot reach. With finely crafted blade-shaped measuring faces, blade micrometers enable accurate measurements in tight and hard-to-reach areas.
These instruments are widely used in precision engineering, tool-making, automotive manufacturing, and aerospace industries where accurate measurement of small details is essential. Their unique design makes them indispensable for applications requiring pinpoint accuracy in confined spaces.
Key Features
Blade-Type Measuring Faces
Ideal for grooves, slots, and narrow recesses.
High-Precision Readings
Available in mechanical and digital versions.
Carbide-Tipped Blades
Long-lasting wear resistance and accuracy.
Slim, Non-Rotating Spindle Design
Prevents twisting and ensures accurate contact.
Applications of Blade Micrometers
- Measuring narrow grooves and recesses in mechanical components
- Machining and fabrication tasks where standard micrometers don’t fit
- Tool and die making for fine detail inspection
- Automotive and aerospace components requiring tight-tolerance checks
- Used in quality control labs for precise dimensional verification
How to Use Blade Micrometers
Set Zero: Calibrate the micrometer using a standard or gauge block.
Align the Blades: Position the blade tips accurately in the groove or slot.
Take the Measurement: Rotate the thimble until light contact is made.
Read the Scale: Read the dimension from the mechanical or digital display.
