## Description

DEWALT DW4910 3IN KNOTTED CUP BRUSH

Review: Great fast service quality and value. Highly recomend.
Review: * 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.

## Questions & Answers

**Q: I have a dewalt dwe402 4  1/2 inch.    with this 3 by 5/8 inch work on it?**
A: Yes. It will work on this grinder as it has a 5/8 spindle and its 3" diameter is less than the max 4/12". You'll have no problem.

**Q: Would this be good to remove bad roll on bed liner from a truck?**
A: It is more common to use a chemical stripper and then various sanding stages.  Using a knotted brush is going to load up and leave surface marks that will have to be sanded and then repainted to match the vehicles surface,  which is where you will be with chemical stripping.  Either way a whole painted bedliner removal is going to be a big job.  If the bed was not prepped properly then the coating may come off easier.

**Q: Would this be suitable to removing a thin concrete overlay from a concrete driveway without removing too much of the underlying broom finish,?**
A: Possibly. It would require a good touch. If the overlay was softer or not married into the brush coat too much. I would do a test patch.

**Q: Will this remove crystalized roofing tar and/or waterproofing? i plan on buy a skil 9296-01 to us with this brush to clean my concrete roof.**
A: The DW4910 has not been tested for this application.  It is ideal for industrial type work on metal.
