Possessing an accuracy of 0.004mm and graduation of 0.0001mm, these 3 point metric internal micrometers are a simple, reliable and highly effective way of measuring the inner diameters of holes for precision working. Available as a set of 2 micrometers and 1 rod or 3 micrometers and 2 rods, each accessory and tool in the set is chrome plated to create a robust product.

Features and Benefits
• Measurement can be taken closer to the bottom of the blind bore, and can be taken into a deep hole with the accompanying extension rods
• Self-centering for easy and speedy working
• Chrome plated for bolstered resistance to corrosion as well as wear and tear
• Available as a set of 2 micrometers and 1 rod or 3 micrometers and 2 rods depending on your preferences and needs
