Buy an internal micrometer to measure the inside diameter dimensions of parts such as bores, grooves, available with a 3.42" - 3.93" inch (87 to 100 mm) measuring range, bearing steel material, and a 150 mm extension rod. It is a 3 point inside micrometer, widely used in mechanical engineering, machining and most mechanical industries for accurate measurement of parts. 

Features

• Inside micrometer is suitable for the precision measurement of blind holes and through holes.
• 3 point inside micrometer is equipped with a 150 mm extension rod, which can measure the size of deep holes easily and conveniently.
• Clear graduations laser-etched on a satin chrome finish for easy reading. Highly durable because of carbide-tipped measuring surfaces. Spindle hardened ground and lapped for ultimate accuracy.
• 87~100 mm internal micrometer built-in force limiter ensures accurate and repeatable readings.

Applications

The inside micrometer is an instrument for the accurate linear measurement of the diameter, thickness, length and other dimensions of solids. 3 point internal micrometer is mainly used to measure internal dimensions such as the internal diameter of a hole or a tube and is widely used in mechanical engineering, machining and most mechanical industries.

Tips: What is a Micrometer?

The micrometer is a commonly used precision measuring tool. The main advantage is that its structural design is stable, so its measurement accuracy is much higher than that of the vernier caliper. Therefore, the micrometer is more suitable for measuring objects with high precision and smoothness than the vernier caliper.
