• THE QUALITY OF MANUFACTURING The MOB Group acquired the European leader in limes and rasps, TALABOT, 30 years ago. The steel of the graters is less loaded with carbon (0.45%) for efficient work on soft materials. At each casting 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 53 HRC for the rasps. MOB graters comply with standard NF E 75 001-75 002. Stabbing of the rasps: the rasp stabbing is used to work soft materials like aluminium, lead, plastics or wood. The rasps finishing is measured in stabbing per cm2. The finishing is: gross (1), medium (2) and fine (3).
