Mitutoyo 146-223 Groove Micrometer with non-rotating spindle, 25 to 50 mm, 12.7 mm

Description

The Mitutoyo 146-223 Groove Micrometer is a metric, analog measuring tool used for determining the width and location of grooves inside bores and tubes. It features a non-rotating spindle to prevent wear and damage to the measuring surface and uses a ratchet stop to ensure a constant measuring force for accurate readings.

Key features

• Reduced wear: The spindle and anvil measure surfaces by expanding, rather than spinning against them, which minimizes wear and tear on both the measuring faces and the workpiece.
• Stable readings: This feature also helps prevent damage and marks on delicate or sensitive surfaces during measurement. 
• Repeatable measurements: A two-directional ratchet stop is built into the thimble to provide a constant measuring force on the spindle. This ensures consistent pressure is applied during every measurement for repeatable and reliable readings.
• User-friendly operation: The ratchet stop is designed for easy use, providing an audible click when the correct measuring force is applied.
• Precision: The micrometer features an accuracy of ±0.01mm (or 10µm) and a graduation of 0.01mm, making it suitable for applications requiring high precision.
• Clear display: The thimble and sleeve have a satin-chrome finish and laser-etched markings for clear, anti-glare reading of both inside and outside measurements.
