Comprehensive toolkits contain various types of micrometers and include protective cases along with calibration standards. Sets of micrometers which cover ranges of 0-25mm to 300-325mm have outside and inside depth micrometers included in them. The tools are built with wear resistant (≥850HV) carbide tipped measuring faces. They also have 11×10⁻⁶/°C thermal compensation handles and are deemed crucial for machine workshop quality control. In compliance of ASME B89.1.1 standard, these tools provide measurement that can be accurately tracked across different materials.

Frequently Asked Questions

What is the precision of gauge blocks?

They offer tolerance classes up to IT0 (±0.0005mm) and surface flatness ≤0.0002mm, ideal for calibrating CMMs, micrometers, and calipers in metrology labs.
