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
