125-150mm Type A Blade Micrometer - 3232 Series (Insize)

125-150mm Type A Blade Micrometer from Insize (3232 Series) is a precision tool designed to measure groove diameters in shafts and keyways with speed and accuracy. Its blade-style design and non-rotating spindle help keep readings stable in tight spaces, making it a reliable choice for engineers, machinists, and technicians who need quick groove measurements.

With a 0.01 mm graduation, a ratchet stop to deliver consistent torque, and setting standards included (except 0–25 mm), this micrometer is ready to calibrate and perform right out of the box. It supports measurements up to 200 mm (8") for a broad range of routine inspections and maintenance tasks.

• Non-rotating spindle for stable groove measurements: Keeps the measuring blade from rotating as you contact the groove, reducing drift and improving repeatability when measuring shaft grooves and keyways.
• 0.01 mm graduation with ratchet stop: Delivers precise, repeatable readings with controlled torque to prevent over-tightening and measurement variation.
• Broad 200 mm (8") range with included setting standards: Enables quick checks across common shaft and keyway sizes; calibration standards are included (except 0–25 mm) to streamline setup and maintain accuracy.

Whether you’re setting up parts on the line, verifying dimension tolerances, or performing routine maintenance, this blade micrometer helps you measure efficiently and confidently. The combination of a blade-style form, precise graduation, and stable spindle supports faster inspections, reduces rework, and keeps you moving from measurement to decision with fewer interruptions.
