✅ Authentic NIETZ SOBAR Industrial Series—engineered for professional metal fabrication, providing high-density wire coverage and superior rotational balance for vibration-free use.
✅ Premium SUS304 Stainless Steel Wire—essential for working on stainless steel and aluminum to prevent "after-rust" and cross-contamination caused by standard carbon steel brushes.
✅ Large 4-Inch (100mm) Cup Diameter—offers a wider cleaning path than the 3-inch version, making it significantly faster for descaling large metal sheets and long weld seams.
✅ High-Tensile Wire (1.5mm / 0.3mm variants)—provides an aggressive yet consistent scrubbing action that removes heavy oxidation, heat tint, and scale without clogging.
✅ Dual Thread Options (M10 x 1.5 / M14 x 2.0)—compatible with a wide range of power tools. The M10 fits most standard 4" grinders, while the M14 is typically for 5" to 7" heavy-duty grinders.
✅ Heavy-Duty Safety Guard—features a reinforced steel housing that secures the stainless steel tufts, preventing wire breakage even during high-RPM industrial operations (Max 12,500 RPM).
