INSIZE 3228-6 Wide Range Three Points Internal Micrometer
Are you looking for a precision, wide-range internal micrometer designed for measuring internal diameters from 4″ to 6″ with high accuracy and stability? The INSIZE 3228-6 has a three-point contact design, this tool self-centers automatically inside the bore and provides highly repeatable measurements. Built with durable materials and fine graduation, it's ideal for quality control, machining, and metrology applications where accuracy and robustness are essential.
Key Features
- Wide Measurement Range (4″to 6″): Covers a broad span so you don’t need multiple micrometers for larger bores.
- Three-Point Contact Design: Three self-centering measuring jaws ensure stable and accurate contact inside bores.
- Fine Graduation: 0.0001″ (0.0001 inch) resolution, so you can detect very small internal diameter changes.
- Carbide Measuring Faces: The measuring contacts are made from carbide for better wear resistance and long-term durability.
- Ratchet Stop: Provides a consistent measuring force, reducing operator error and improving repeatability.
- Setting Ring Included: Includes a 4″ diameter setting ring for calibration / zeroing the micrometer.
- Inspection Certificate: Supplied with a manufacturer inspection certificate for traceability and quality assurance.
