Industrial-grade quality: This dual-purpose locking pliers set is a completely new upgraded industrial product. After overall quenching, it has higher hardness and possesses excellent durability and reliability. Whether facing high-intensity working environments or frequent usage, it can maintain stable performance, is not prone to damage, and provides reliable tool support for professionals. Integrated molding design: It adopts the integrated molding process for the pliers body, ensuring a tight connection between the plier head and the plier body, making it less likely to break and having a longer service life. At the same time, it uses selected 45# high-carbon steel material with a hardness of up to HRC55. After phosphating processing, it has better rust prevention effects, ensuring that the tool can maintain a good working condition in various complex environments. Multi-functional dual use: This set can quickly distinguish between shaft use and cavity use, meeting different usage needs. The original state of the plier head is closed, and by firmly grasping the handle and opening it outward, it can be used separately for installing and removing external spring rings (shaft use) and external spring rings (cavity use). The operation is simple, the function is practical, and it greatly improves work efficiency. High precision: The standard plier head design has high accuracy and small error, remaining straight and not deviating during use, and is less likely to break. Whether for precise installation or disassembly of locking rings, it can operate precisely, ensuring the accuracy and high-quality completion of the work. Comfortable anti-slip: The handle part adopts an eight-shaped anti-slip design, which is more stable and less likely to fall off, providing a good grip for the user. Even when using for a long time or with sweaty hands, it can ensure the safety and stability of the operation, reducing hand fatigue and enhancing the work experience.
