The 25-50mm Type A Blade Micrometer from Insize (3232 Series) is a precision instrument designed to measure groove diameters in shafts and keyways with quick, repeatable readings. Featuring a non-rotating spindle and a ratchet stop for consistent results, this blade micrometer delivers 0.01 mm graduations across a range up to 200 mm and includes setting standards (except 0-25 mm) to speed setup and maintain accuracy on the line.
- Non-rotating spindle for repeatable measurements: Eliminates drift during measurement, ensuring consistent readings on groove diameters and keyways.
- Fine 0.01 mm graduation with wide range: Provides precise, easy-to-read increments for accurate tolerancing across the full measuring span.
- Ratchet stop with included setting standards: Protects against over-tightening and simplifies quick, reliable setup (setting standards included except 0-25 mm).
Designed for everyday use in engineering shops and maintenance environments, this micrometer helps you measure groove diameters quickly and confidently, reducing rework and ensuring precise fits for shafts and keyways across production and QC tasks.
