The 25-50mm Type B Blade Micrometer from Insize is designed to measure groove diameters in shafts and keyways with precision and speed. Its blade-style measuring faces fit neatly into tight slots, helping you capture consistent readings in challenging setups.
Insize 3232 Series models deliver a non-rotating spindle for stable contact, a clear 0.01 mm graduation for accurate sizing, and a ratchet stop to prevent over-tightening. Setting standards are included (except 0-25mm), and the instrument can measure up to 200 mm (8 inches), making it versatile for a wide range of parts.
- Non-rotating spindle for consistent groove readings: Keeps contact stable as you measure shafts and keyways, reducing reading drift and improving repeatability.
- 0.01 mm graduation for precise results: Fine graduations deliver repeatable measurements on small groove diameters and tight tolerances.
- Ready-to-use with included setting standards and ratchet stop: Quick setup with included standards (except 0-25mm) and a ratchet stop to protect the tool and your readings.
This blade micrometer helps you streamline inspection workflows, deliver reliable groove measurements, and maintain tight tolerances across a range of parts—making it a dependable choice for shop floors, engineering labs, and maintenance teams.
