Reinforced construction 55-65 HRC Nickel-plating In the construction of the reinforced series of joint and pliers tools, a hinge is used, which is positioned closer to the working surface compared to traditional pliers and wire cutters. This technical solution allows for greater force to be transmitted to the jaws and cutting edges of the tool with less force applied to the handles. And the use of an overhead hinge type makes the tool lighter without sacrificing quality characteristics. The updated and calibrated geometry of the working surfaces ensures greater efficiency when working in hard-to-reach areas. - thermal treatment of the entire tool surface: 42-48 HRC; - induction hardening of the cutting edges: 55-65 HRC; - ergonomic two-component handles. Set composition: - 411 430 Combined reinforced pliers 130 mm; - 412 430 Extended reinforced pliers 130 mm; - 414 430 Reinforced wire cutters 130 mm.
