Mitutoyo 146-224 Groove Micrometer with non-rotating spindle, 50 to 75 mm, 12.7 mm

Description

The Mitutoyo 146-224 Groove Micrometer is a mechanical, analog tool designed to precisely measure the width, depth, and location of internal and external grooves. Key features include a non-rotating spindle and a two-directional ratchet stop for repeatable, consistent measurements.

Key features

• Flanged measuring faces: Both the spindle and anvil feature 12.7 mm diameter discs, or flanges. This design is purpose-built to fit into grooves and bores, allowing for accurate measurement of their width and location.
• Dual-scale vernier: The micrometer has two sets of graduations on its sleeve, allowing it to take both inside dimension (ID) and outside dimension (OD) measurements directly from the scale.
• Bidirectional ratchet stop: This mechanism provides uniform pressure on the measuring surfaces, ensuring consistent contact force between different operators and reducing measurement variation.
• High accuracy: The 146-224 offers a high level of precision with a graduation of 0.01 mm and an accuracy of ±10 μm.
• Wear resistance: The measuring discs are made from hardened steel to resist wear and maintain accuracy over time.
• Easy to read: The satin-chrome finish on the sleeve and thimble resists rust and provides a low-glare surface, making the laser-etched scale easier to read.
• Ergonomic design: The micrometer is precision-balanced for comfortable handling and improved readability during use.
• Included case: It comes supplied in a plastic, fitted case for secure storage.
