This three-piece drill brush set transforms your cordless drill into a powerful cleaning tool that tackles stubborn stains quickly and efficiently. The set includes a two-inch small brush for tight corners and crevices, a three-and-a-half-inch medium brush for versatile cleaning tasks, and a four-inch large brush for expansive surfaces. Each brush features a quarter-inch mounting shaft that attaches securely to standard cordless drills, allowing you to clean tiles, tubs, sinks, toilets, baseboards, shower enclosures, countertops, and other metal, glass, porcelain, or plastic surfaces with minimal effort. The brushes are constructed with high-density polypropylene bristles that resist abrasion and corrosion while delivering thorough cleaning without scratching or leaving marks on surfaces. The durable nickel-plated iron shafts ensure reliable performance across multiple cleaning projects in bathrooms, kitchens, and other areas of your home. The quick-change shaft design makes switching between brush sizes simple and convenient.

Each brush is lightweight and easy to handle, with the small brush weighing approximately one-and-a-half ounces, the medium brush three ounces, and the large brush four ounces.
