Material - Made of bearing steel, with high hardness, strong wear resistance, and heat treatment processing for durability.
Feature - 0.001mm precision, accurate measurement. Roughness is less than 0.2UM, smooth surface without burrs.
Application - Used to measure the size or depth of holes, check the distance between two holes, and can also be used as a go-no-go gauge. Widely used in high-precision technical fields such as electronic boards, circuit boards, and precision machinery manufacturing. An essential tool for the standardization of detection holes.
Note - To keep the measurement accuracy, please do not scratch the surface, and do the anti-rust treatment after use.
