【3-in-1 Multifunctional】: This automatic wire stripper can be used to strip, cut, and crimp wires. It can freely strip wires with a cross-section of less than 6 mm² and crimp pre-insulated round terminals and bare wire terminals with a cross-section between 0.5 and 6 mm². It can effortlessly cut wires of any material. 【Adjustable Stripping Length】: The self-adjusting wire stripper is equipped with a rotating gauge that allows you to select the length of insulation to be stripped (maximum width of 11 mm). 【Retractable Torsion Spring Structure】: The wire stripper uses a hidden internal spring design, which provides a gentle stripping force to reduce impact, minimize the risk of damage and rust, and requires no adjustment. 【High Quality】: The automatic wire stripper is made of high-quality, high-carbon steel with a black coated surface, ensuring durability and reliability. The blades are made of SK5 steel with a hardness of 48-52 HRC, offering strength and reliability. It is equipped with a PP+TPR rubber handle, providing a comfortable grip and reducing hand fatigue during use. 【Wide Range of Applications】: The 3-in-1 Cable Stripper has a wide range of applications, suitable for single-conductor wires, multi-conductor wires, thick wires, copper wires, aluminum wires, stranded wires, solid wires, multi-strand wires, flat wires, and other types of wires.
