ToolDateCheck Reads the Date Stamped on Your Power Tools

Field notes

The site separates brand-specific decoding rules instead of treating every code as the same kind of identifier. Its coverage includes overlapping formats, battery-specific systems, and cases where a serial number contains the date or where a separate stamp must be found on the housing. Results retain uncertainty: a one-digit year may produce several surviving decade candidates, while Makita readings are marked disputed rather than presented as settled fact.
