These wire wheel brushes are designed for light to medium-duty work and delivers rapid stock removal from a wide variety of surfaces. The bristles are made from hardened dipped brassed steel wire, which gives a high level of durability and resistance to oxidation. The brush is strong enough to provide reliable performance, and the crimping is flexible to tackle recessed areas and irregular surfaces. The wheel shape is designed to work perpendicular to the surface, making it ideal for smaller and tighter areas. Fitted with a non-slip 6.35mm hex shank. Compatible with most drill drivers and drills with a 13mm chuck.
