Mitutoyo 105-411 Outside Micrometer Anvil Extension Collar, 1300 to 1400 mm

Key features

The Mitutoyo 105-411 is an outside micrometer that includes anvil extension collars to expand its measuring range to 1300–1400mm. It is not a separate extension collar, but rather a large-capacity micrometer that uses extension collars as part of its design.

Key features

• Extension anvil collars: The micrometer uses multiple 50mm extension collars that allow it to be configured for its full 1300–1400mm measuring range. This design provides greater versatility compared to standard micrometers with a fixed range.
• Lightweight, rigid frame: For models with a range over 1000mm, including the 105-411, the frame is constructed from a combination of square and round pipe sections. This makes it lighter and easier to handle for large-scale measurements while maintaining high rigidity for accuracy.
• Extended spindle stroke: A 50mm spindle stroke provides a larger measuring range than the typical 25mm found on most micrometers.
• Carbide-tipped measuring faces: The measuring surfaces of the anvil and spindle are carbide-tipped and feature a micro-lap finish. This provides high wear resistance and ensures consistent accuracy over many uses.
• Constant force ratchet stop: A ratchet stop mechanism provides a consistent measuring force, which helps prevent over-tightening and ensures repeatable measurements.
• Zero-setting standards: The micrometer is supplied with zero-setting standards for each of its ranges, allowing for precise calibration.
• Workpiece stopper: For models with a range over 1000mm, an adjustable workpiece stopper is included for added convenience.
• Protective case: The micrometer comes in a fitted wooden case to protect the precision instrument during storage and transport.
