Application Summary AI generated
GB/T 9058-2004 specifies the design, dimensions, and accuracy requirements for micrometers with prismatically arranged measuring faces, commonly known as odd-flute micrometers. It is applied in precision engineering and manufacturing to measure the diameters of cutting tools, such as taps, reamers, and end mills, which have an odd number of flutes or cutting edges. This standard ensures consistent measurement of these tools in quality control and inspection contexts within the metalworking industry.
