Mitutoyo 146-222 Groove Micrometer with non-rotating spindle, 0 to 25 mm, 12.7 mm

Description

The Mitutoyo 146-222 Groove Micrometer is a specialized precision tool used to measure the width, depth, and location of grooves, recesses, and shoulders, both on outside and inside bores. The model features a non-rotating spindle and a 12.7 mm diameter flange. 

Key features 

• Non-rotating spindle: This feature prevents damage to delicate workpiece surfaces and helps ensure stable, consistent positioning during measurement.
• Two-directional ratchet stop: The bidirectional ratchet mechanism applies a constant, uniform measuring force to the workpiece. This prevents overtightening and helps achieve precise, repeatable measurements.
• Flanged measuring faces: The specialized, flange-shaped anvils are designed to measure the width and location of grooves, recesses, and shoulders inside and outside bores.
• Dual scales: The vernier scale features separate metric graduations for directly reading both inside diameter (ID) and outside diameter (OD) measurements.
• High precision: The micrometer offers a high degree of accuracy (\(\pm 10\mu \)m) and resolution (0.01 mm) for precise dimensional verification.
• Durable construction: The measuring surfaces are made of hardened steel for increased wear resistance and durability. The thimble and sleeve have a satin chrome finish to resist rust and glare for easier reading.
