Which code does this activity belong in?
Code 333515 covers replacements and attachments for machine tools themselves, such as drill bits, taps, dies, and measuring devices that mount onto metal cutting or forming equipment. It is distinct from code 333517, which manufactures the machine tools that these accessories equip. Code 333514 manufactures custom dies and fixtures made to customer specifications for specialized production processes, whereas 333515 produces standardized cutting tool accessories for general use on machine tools. Code 333511, industrial mold manufacturing, differs fundamentally as it produces molds for casting or forming materials, not accessories that attach to machine tools.
