A rich variety of sizes can meet the needs of different users and different work scenarios. The vise body and slide bar of the bench vise are made of high-quality gray cast iron HT200. HT200 gray cast iron has good casting properties, vibration damping, and wear resistance, capable of withstanding certain clamping forces, ensuring that the bench vise does not deform easily during long-term use, providing a stable clamping environment for the workpiece. The overall design is compact and lightweight, with a relatively small gross/net weight, making it convenient for users to carry and move. Whether in a studio, workshop, or outdoor job site, it can be used easily. The operation is simple and easy to understand, allowing users to quickly learn and improve work efficiency.
