HEAVY-DUTY TWIST KNOT STEEL WIRE | 工业级高硬度扭丝结构: Features aggressive, thick steel wires twisted into rigid knots. This "Rough" (粗) grade provides maximum scrubbing power for heavy-duty applications where standard crimped brushes are insufficient.
采用高强度扭绞式粗钢丝结构，提供极强的切削力。此款“粗钢线”级别专为重型作业而设计，能轻松应对普通波浪形钢丝刷无法处理的顽固附着物。

3-INCH AGGRESSIVE CUP DESIGN | 3寸 强力型碗型结构: The 3" (75mm) diameter cup shape is engineered for fast material removal on large flat surfaces. The rigid knot design ensures the wire remains upright under heavy pressure for consistent, aggressive cleaning.
3寸 (75mm) 直径的碗型结构专为大面积表面的快速切削而设计。稳固的扭丝结构确保在重压作业下钢丝不弯曲，始终保持强劲且一致的清洁效果。

HEAVY RUST & PAINT REMOVAL | 强力去锈与厚漆剥离: Optimized for the toughest cleaning tasks, including removing heavy rust, thick layers of paint, weld spatter, scale, and corrosion from structural steel and heavy machinery.
专为最严苛的清洁任务而优化，可高效清除结构钢及重型机械表面的厚重浮锈、厚漆层、焊渣、氧化皮及深度腐蚀层。

M10 x 1.5mm / M14 THREADED ARBOR | 标准加固螺纹接口: Equipped with a precision-machined threaded nut (typically M10 x 1.5mm) that fits securely onto standard 4" angle grinders, ensuring stable high-speed rotation and maximum safety under high torque.
配备精密加工的标准螺纹接口（通常为 M10 x 1.5mm），可稳固锁紧于标准 4寸 角磨机，确保在高扭矩与高速旋转下依然保持极高的稳定性与安全性。

HIGH-TENSILE CARBON STEEL DURABILITY | 高张力碳钢持久耐用: Manufactured from high-tensile carbon steel that is heat-treated for maximum toughness. The twist knot design significantly reduces wire breakage, ensuring a longer service life during continuous industrial use.
由经过热处理的高张力碳钢制成，具备卓越的韧性。扭丝设计显著降低了钢丝在高速冲击下的折断率，确保在持续的工业高强度作业中拥有更长的使用寿命。
