* Excellent for Heavy-Duty Surface Prep This cup brush removes rust, old paint, and weld scale quickly and efficiently. The knotted carbon steel wire is tough and long-lasting, and it felt balanced on my angle grinder with minimal vibration. Highly recommended for metalworking and fabrication jobs! * Great Value & Quality Bought this to clean up some steel beams before painting — glad I did. It’s clearly higher quality than generic brushes. The internal holding plate keeps it steady even at high speeds, and the wire quality feels very solid. * Smooth Performance, Easy to Use Installation was simple (fits standard 5/8-11 grinders) and it worked smoothly even on tough rust spots. I paired this with proper PPE and it made quick work of cleaning metal surfaces. A good accessory to have in your tool kit. * Professional-Grade Accessory I use this cup brush for prep work before welding and painting — it’s aggressive enough to remove scale but sturdy enough to last through multiple projects. DeWalt’s build quality shows. * Solid for the Price Great value considering how long this brush lasts compared to less expensive brands. Just be sure to use with safety gear — it’s aggressive! Final take: 👍 Fits most angle grinders with a 5/8-11 arbor bolt. 👍 Ideal for rust, weld scale, and paint removal on ferrous metals. ⚠️ Wear eye and hand protection — knotted wire brushes can shed small pieces if not handled safely. ⚠️ Not designed for stainless steel or very thin/delicate surfaces.

Excelente calidad, el encastre es de rosca para esmeril angular de 5/8 lo más común en México, limpie óxido profundo de toda una puerta y parece que es eterno pues no se desgasto ni un 10%.
