Premium Material - Sheet metal benders, crafted from AISI 1045 steel, undergo a forging process for durability and strength. This process increases material density and uniformity, resulting in robust metal bending pliers that can handle heavy loads and pressures, ensuring a long service life. Durable Coating - The surface of sheet bending pliers is treated with electrophoretic coating, which not only enhances the tool's aesthetics but also improves its wear and corrosion resistance. It resists oil and moisture, maintaining its performance in various environments. Heat-Treated - Professionally heat-treated to a hardness of 35-45 HRC, the sheet metal bending tool is hard enough for precise metal bending while maintaining good toughness. This hardness allows the tool to excel in a variety of metalworking tasks. Ergonomic Design - The handles of sheet metal pliers are made with a plastic dip process, offering a soft and comfortable grip that enhances operational safety. This design makes bending work easier and more accurate, reducing fatigue even with extended use. Multi-Functionality - The AWMWOCS 3pcs metal bending pliers set includes straight, 45°, and 90° sheet metal bending pliers, meeting the bending needs of various angles. Whether in roofing, HVAC, vehicle maintenance, or DIY projects, it provides efficient metal bending solutions. The AWMWOCS 3-piece manual seamer sheet metal tool set combines straight, 45° and 90° sheet metal bending pliers in one, making it an ideal choice for roofing construction, HVAC installation, workshop maintenance or personal DIY projects. This set of tools is forged from AISI 1045 steel to ensure the durability and strength of the tools, while the wear-resistant coating treated with electrophoresis improves the corrosion resistance and appearance of the tools. The hardness after professional heat treatment reaches 35-45 HRC, making the tool both hard and tough, while the ergonomic handle design of the plastic dipping process provides a soft and comfortable grip and excellent anti-slip performance, making it less fatigue-prone even after long-term operation. Whether it is precise metal bending or daily heavy-duty operations, the AWMWOCS 3-piece manual seamer sheet metal tool set can provide you with efficient and precise solutions.
