USE
- For hole diameter inspection
MATERIAL
- Gauge: Carbide
- Handle: Aluminum
FEATURES
- GO/NOGO gauge for testing fit of shaft in a hole based on maximum and minimum allowable dimensions
- Excellent wear resistance for 20〜30 times longer service life than steel
- The coefficient of thermal expansion（ 5×10-6 /K） is ½ that of steel, so the changes due to temperature are small
- Less likely to be scratched or damaged due to high hardness
- Economical – longer span of periodic calibration compared to steel gauge
- Provided with inspection report
SPECIFICATIONS
- Class H7 for manufacturing
- Surface roughness: Within Ra0.2μm
