The INSIZE 3290-953A V-Anvil Micrometer is a precision mechanical measuring instrument designed for measuring the diameter of parts and cutting tools with odd grooves, such as taps, reamers, and end mills. It provides an 80–95 mm measuring range, 0.01 mm graduation, and 7 µm accuracy. The 3-flute V-anvil configuration features a 60° included angle, allowing suitable grooved components to be positioned securely between the measuring surfaces. The micrometer also features carbide measuring faces and a ratchet stop for durable contact and controlled measuring force.
Key Features
1. 80–95mm Measuring Range
The 3290-953A offers an 80–95 mm measuring range, making it suitable for measuring compatible larger-diameter grooved components and cutting tools within this range.
2. 3-Flute V-Anvil Configuration
The micrometer uses a 3-flute V-anvil design with a 60° included angle. This configuration is intended for measuring suitable components with odd grooves, including taps, reamers, and end mills.
3. 0.01mm Graduation & 7µm Accuracy
The instrument provides a 0.01 mm graduation and 7 µm accuracy, supporting detailed dimensional inspection of suitable grooved parts and cutting tools.
4. Carbide Measuring Faces
The carbide measuring faces provide durable contact surfaces designed for repeated measurement applications in machine shops, tool rooms, and manufacturing environments.
5. Ratchet Stop & Setting Standard
The ratchet stop helps maintain controlled measuring force for consistent readings. The 3290 series is supplied with setting standards for applicable models, supporting convenient measurement setup and adjustment.
