The INSIZE 3290-1055A V-Anvil Micrometer is a precision mechanical measuring instrument designed for accurate measurement of the diameter of cutting tools and components with odd numbers of grooves or flutes, such as taps, reamers and end mills. It provides an 85–105 mm measuring range, 0.01 mm graduation, and 8 µm accuracy. The 3290-1055A features a 5-flute V-anvil configuration, carbide measuring faces and a ratchet stop for controlled measuring force. It is suitable for CNC machining, tool inspection, manufacturing quality control, tool rooms, engineering workshops and precision dimensional measurement.
Key Features
1. 85–105mm Measuring Range
The 3290-1055A provides an 85–105 mm measuring range, making it suitable for larger cutting tools, cylindrical components and other compatible workpieces requiring V-anvil measurement.
2. 5-Flute V-Anvil Design
The micrometer uses a 5-flute V-anvil configuration designed for measuring suitable components with an odd number of grooves or flutes. This makes it particularly useful for specialized cutting-tool inspection.
3. 0.01mm Graduation
The 0.01 mm graduation provides detailed mechanical measurement readings for dimensional inspection and quality-control applications.
4. 8µm Accuracy
INSIZE specifies 8 µm accuracy for the 3290-1055A, providing suitable precision for dimensional inspection of compatible cutting tools and components.
5. Carbide Measuring Faces & Ratchet Stop
The micrometer features carbide measuring faces for durable contact surfaces and a ratchet stop to help maintain consistent measuring pressure. A setting standard is supplied for applicable ranges.
