Review on 🔍 Optimized for SEO: DEWALT DW4917 6 Inch Knotted Brush for Enhanced Performance by Adam Martinez

This is an upgrade from my previous 2 star rating to a 5 star rating. The update follows the first review. Quite expensive. I liked it at first but it has developed a vibration that only gets worse given its large mass, it's more of a massage for my hands than anything else. It feels like it's about to explode, so I only use it when my smaller 4.5" mug can't cut through it. I use them for daily descaling of CNC plasma cut parts. Update turns out that the wobble I was feeling with this mug installed was actually an issue with my coffee grinder itself and it only showed up when it had this big wheel on it. Over time the issue got so bad that I saw how screws are loosened on the gearbox housing. I tightened them with Loctite and the vibration was gone. I just ordered another one.
