This set of wire brushes is designed for light to medium-duty work and delivers rapid stock removal from a wide variety of surfaces. The brushes are made from hardened dipped brassed steel wire, which gives a high level of durability and resistance to oxidation. The brushes are strong enough to provide reliable performance, and the crimping is flexible to tackle recessed areas and irregular surfaces. The set includes a 25mm wire end brush, 75mm wire cup brush, and three wire wheel brushes (50, 75, 100mm). Fitted with a non-slip 6.35mm hex shank. Compatible with most drill drivers and drills with a 13mm chuck.
