Actions against fakes of PGM mark

Since 2009, more than 56000 faked drill bits and packaging have been seized during raid actions. The raids have been conducted on behalf of PGM by the Chinese authority Administration for Industry and Commerce (AIC).  The seized drill bits have been destroyed and the counterfeiters have been penalized.
