• QUALITY OF MANUFACTURE: the group MOB acquired 30 years ago the European leader of limes and rasps, TALABOT. The files are characterized by a long life of the cut thanks to steel heavily loaded with carbon (1.3 to 1.4%). It is alloyed with chrome for a powerful bite. At each pour, MOB checks the chemical composition of the steels. The perfect control of the quench, a crucial operation for the quality of the cut, makes it possible to guarantee hardnesses of 65 ± 2 HRC for the files and 53 HRC for the rasps. The mob files and rasps comply with standard NF E 75 001-75 002. Dimensions: the files and rasps are defined by their length (without the silk) in mm. Size of the mechanical files: cross size. The degree of fineness of the size is measured in number of teeth per cm of length. This ratio varies according to the size of the file. The finishes are: bastards for roughing (1), half-soft (2) for routine work, soft (3) for finishing.
