ASIMETO 209-25-0 Three-Point Internal Micrometer 16-20 mm, Resolution 0.005 mm

ASIMETO 209-25-0 Three-Point Internal Micrometer, Range 16-20 mm, Resolution 0.005 mm
The ASIMETO 209-25-0 Three-Point Internal Micrometer is a precision measuring tool for measuring internal bore diameters, emphasizing high durability and precision in an analog mechanical format. Designed to German engineering standards, it is ideal for machinists seeking measurement confidence without relying on electrical systems or batteries. With a synchronized 3-point contact mechanism, the tool automatically self-centers within the bore, delivering consistent measurement readings every time.

Features 
- Self-Centering Mechanism: The 3-point contact self-centering system minimizes errors from tilting the tool, ensuring the most accurate and true readings.
- Carbide-Tipped Contact Points: Measuring faces are made of high-grade carbide, resistant to scratching and wear, extending service life even under continuous use.
- Ratchet Stop: Helps maintain constant measuring force, preventing over-tightening that could distort readings or damage the workpiece.
- High-Quality Finish: Satin chrome-plated finish reduces glare and makes reading scale markings clearer.
- Deep Hole Measurement: Can be used with an extension rod to measure deep holes (accessory included in set).

Applications
- Internal diameter measurement of cylinders, engines, and bearings
- Bore inspection in lathe-turned and milled workpieces
- Quality control in aerospace and automotive parts manufacturing
- Heavy machinery maintenance requiring high precision
