The GOST 2685-75 standard was developed during the Soviet era, when the country's manufacturing sector was heavily focused on producing high-quality machinery and tools for various industries, including aerospace, automotive, and construction. The standard was created to ensure that metal cutting tools produced in the Soviet Union met specific requirements for performance, safety, and interchangeability.
: E.g., AK7ch. High strength after heat treatment.
In 2015, the Russian Federation began harmonizing its GOST standards with ISO. is currently under review for replacement by GOST ISO 1224-1 (Instrument bearings – single-row angular contact ball bearings). However, due to the massive installed base of legacy machinery, the 2025 to 2030 transition period means the PDF will remain a valid reference for decades. gost 2685-75 pdf
