Special CharacteristicsThe cylindrical blade allows access to deep-set locations. Extra long blade up to 300 mm for hard-to-reach, deep-set screws. Inline heat treatment: +100% lifespan and +100% resistance. Handle material: Soft Grip for more comfort and always resistant to chemical products. "Tri-coating" blade treatment (Zinc-Nickel-Chrome): 4 times more resistant to corrosion. Optimized handle ergonomics: +10% higher torque. Laser marking: for greater wear resistance. Profile finishing by digital control: better screw fit by increasing torque transfer and reducing wear.Technical DataDiameter (mm): 19 Diameter d1 x L1 (mm): 3.0 x 75 Length L [mm]: 178 Length L2 [mm]: 94 Thickness E: 0.5 Thickness x width (E x l): 0.5 x 3.0 A [mm]: 3.0
