INSIZE 3506 Digital Outside Micrometer with Interchangeable Anvils
The INSIZE 3506 Digital Outside Micrometer with Interchangeable Anvils is a precision large-capacity outside micrometer designed for accurate measurement of large workpieces and components. Its interchangeable-anvil design allows the instrument to cover extended measuring ranges while maintaining a practical, rigid micrometer configuration.
CRB Supply offers the 3506 series from 400–1000 mm (16–40"), making these micrometers well suited for large-diameter shafts, precision-machined components, fabricated parts, and other applications where conventional micrometers do not provide sufficient capacity.
The digital readout provides direct metric and inch measurements, while the carbide measuring faces, ratchet stop, and supplied setting standards support repeatable precision inspection.

Interchangeable-Anvil Design
The 3506 uses interchangeable anvils to accommodate different measuring ranges. This design allows one micrometer frame to provide substantial measurement capacity while maintaining the familiar operating principles of a precision outside micrometer.
The supplied setting standards allow the micrometer to be properly referenced for its intended measuring range before inspection.
Precision Measurement Features
The 3506 combines a large-capacity mechanical frame with a digital measurement system. Carbide measuring faces provide wear resistance during repeated inspection, while the ratchet stop helps maintain consistent measuring pressure between measurements.
The digital display supports metric/inch conversion and ABS/INC measurement modes. The integrated data output interface can also be used for compatible measurement-data collection systems.
