Two brush combo kit, fits all cordless drills and impact drivers. Durable high quality nylon bristles are great for scrubbing and cleaning fiberglass, porcelain, linoleum, pots, pans, sinks, faucets, tile, and grout. This kit includes a mini size green medium original Drillbrush. This brush is great for getting into tight corners and crevices that larger brushes may clean less effectively. The smaller diameter of the round 2 inch diameter scrub brush allows access to tight and hard to reach areas such as on or around kitchen sinks, faucets, and appliances.
