Mitutoyo 105-434 Outside Micrometer Anvil Extension Collar, 64 to 68”

Description

The Mitutoyo 105-434 Outside Micrometer with Extension Anvil Collars is a large, vernier-style micrometer designed for measuring broad external dimensions. It has a measuring range of 64 to 68 inches. Instead of a solid frame, it uses a lightweight tube construction with interchangeable extension collars to achieve its wide measurement range.

Key features

• Wide measuring range with extension collars: This is the most significant feature. The micrometer uses 2-inch extension anvil collars to change its range, allowing it to cover large external dimensions from 64 to 68 inches.
• Lightweight and rigid frame: The frame is constructed from a combination of square and round pipes. This provides a balance of lightness and high rigidity, which is essential for maintaining accuracy on such a large micrometer.
• Carbide-tipped measuring faces: The measuring surfaces are carbide-tipped with a micro-lap finish. This makes them highly resistant to wear and helps maintain accuracy over the tool's lifetime.
• Constant force mechanism: A ratchet stop is included to ensure that constant, repeatable measuring pressure is applied to the workpiece. This eliminates variation in readings due to different users or measurement techniques.
• 50mm (2-inch) spindle stroke: This allows for a large measuring range with a single anvil collar setup.
• Zero-setting standards: The tool is supplied with zero-setting standard bars for each specified range, ensuring proper calibration and high accuracy.
• Workpiece stopper: For models with a range over 40 inches (including the 105-434), an adjustable workpiece stopper is included for added stability during measurement.
• Convenient spindle lock: The micrometer features a spindle lock to secure a measurement and prevent the spindle from moving after the reading has been taken.
• High-quality finish: The thimble and sleeve have a satin-chrome finish, which prevents glare and corrosion.
• Fitted wooden case: The tool is supplied in a durable, fitted wooden case for protection and storage.
