PREMIUM HIGH-DENSITY BRASS WIRE | 优质高密度原色铜丝: Manufactured with high-grade crimped brass wire that provides a flexible yet effective scrubbing action. The non-sparking nature of brass makes it significantly safer for use in environments where flammable gases or materials are present.
采用高密度优质波浪形原色铜丝精制而成，具备良好的柔韧性与高效的擦洗能力。由于铜丝具有不产生火花的特性，在存有易燃气体或材料的作业环境下比钢丝刷更加安全。

4-INCH WIDE COVERAGE CUP DESIGN | 4寸 大面积平稳碗型结构: The 4" (100mm) diameter cup shape provides extensive surface coverage, making it ideal for fast cleaning and polishing of large flat metal plates, structural beams, and engine components.
4寸 (100mm) 直径的碗型结构提供了宽阔的表面覆盖范围，是大型金属板材、结构梁及发动机部件进行快速清洁与抛光的理想选择。

M14 x 2.0mm THREADED ARBOR | M14 x 2.0mm 标准工业螺纹接口: Specifically equipped with an M14 x 2.0mm precision-machined threaded nut, designed to fit securely onto larger 4.5", 5", and 7" industrial angle grinders for stable, high-torque operation.
专门配备 M14 x 2.0mm 精密加工标准螺纹接口，可牢固安装在 4.5寸、5寸 及 7寸 等大型工业角磨机上，确保在高扭矩作业下依然稳固不晃动。

NON-ABRASIVE SURFACE FINISHING | 软性金属无损表面处理: Optimized for cleaning, deburring, and polishing without gouging or damaging the base material. Perfect for sensitive surfaces such as brass, copper, aluminum, and light-gauge steel where surface integrity is critical.
专为清洁、去毛刺及抛光而优化，且不会伤及基材表面。非常适合处理黄铜、红铜、铝材及薄钢片等对表面完整性要求极高的敏感材质。

RUST & OXIDATION REMOVAL | 强力清除浮锈与氧化层: Highly effective at removing surface rust, light scale, oxidation, and old paint from metal parts, restoring the natural metallic shine with minimal effort and reducing preparation time.
能高效清除金属零件表面的浮锈、轻微水垢、氧化层及旧漆层。只需较小的力度即可恢复金属原有的光泽，显著缩短表面预处理所需的时间。
