The INSIZE 3206-400A Outside Micrometer With Interchangeable Anvils is a precision mechanical measuring instrument designed for accurate outside measurement of large components across a 300–400 mm / 12–16 inch measuring range. Its interchangeable-anvil design allows multiple measuring positions to be covered with a single micrometer, providing a practical solution for large shafts, cylindrical components, machine parts, fabricated components, and other industrial workpieces. The 3206-400A features 0.01 mm graduation and 9 µm accuracy, along with carbide measuring faces and a ratchet stop for controlled and repeatable measurement. It is suitable for CNC machining, turning, milling, manufacturing inspection, quality control, engineering workshops, and tool-room applications.
Key Features
1. Large 300–400mm Measuring Range
The 3206-400A provides a 300–400 mm / 12–16 inch measuring range, making it suitable for measuring large shafts, cylindrical components, machine parts, fabricated workpieces, and other external dimensions within its capacity.
2. Interchangeable Anvil System
The interchangeable-anvil configuration allows the micrometer to be adjusted for different measuring positions throughout the 300–400 mm range. This provides greater flexibility than using several fixed-range micrometers and is useful for large-component inspection.
3. 0.01mm Graduation & 9µm Accuracy
The micrometer provides 0.01 mm graduation and 9 µm accuracy, allowing detailed mechanical measurement readings for precision inspection, machining, manufacturing, and quality-control applications.
4. Carbide Measuring Faces
The carbide measuring faces provide durable contact surfaces suitable for repeated measurement of compatible workpieces. This makes the micrometer appropriate for regular use in machine shops, inspection departments, and manufacturing environments.
5. Ratchet Stop & Setting Standards
The ratchet stop helps provide controlled measuring force for consistent readings. The interchangeable-anvil system is supported by suitable setting standards for reference setting across the measuring range.
