Description
The 0-300 mm Metric Outside Micrometer Set from Insize 3203 Series delivers precise, repeatable measurements across a broad range. Designed for machinists, inspectors, and workshop teams, it combines reliability with robust construction for everyday metrology tasks.
- Range: 0–300 mm outside micrometer for measuring large parts and shafts
- Graduation: 0.01 mm resolution for fine, consistent readings
- Carbide measuring faces: enhanced wear resistance to extend tool life in busy shop environments
- Includes setting standards: setting standards supplied for quick, repeatable measurements (except 0–25 mm)
- Durable construction: rugged frame and precision-ground spindle designed for daily use
- Protective storage: comes in a dedicated carrying case to protect the instrument and keep your workspace organized
With 0.01 mm graduation, you gain finer control over dimensions, helping reduce rework on components such as shafts and housings. The carbide measuring faces offer long tool life by standing up to routine wear in a fast-paced machine shop. The included setting standards streamline quick setup and consistent readings across parts and operators, while the protective case keeps the kit organized and ready for use on the shop floor or in the field.
