The 1-2" Imperial Blade Micrometer from Insize, part of the 3232 Series, is a precision measuring tool designed specifically for groove diameter work. It’s ideal for engineers, machinists, service professionals, and hobbyists who need fast, repeatable readings of shaft grooves and keyways. Featuring a non-rotating spindle and a ratchet stop, it delivers stable contact and consistent pressure for reliable measurements, with setting standards included (except 0-25mm) to simplify quick calibration. Its effective range reaches up to 8 inches, making it versatile for a wide range of components.
- Non-rotating spindle: Provides stable, repeatable contact for groove and keyway measurements, reducing variation caused by spindle rotation and improving consistency across tasks.
- Ratchet stop: Ensures uniform measuring force every time, preventing over-tightening and enhancing measurement reproducibility even after repeated use.
- Calibration standards included (except 0-25mm): Speeds setup and verification, helping you trust every dimension from the first measurement to the last without extra tools.
This blade micrometer is built for dependable performance in real-world conditions—shop floors, maintenance bays, and on-site projects alike. It supports quick, accurate groove diameter checks, helping you confirm fits, reduce downstream rework, and maintain tight tolerances with confidence.
