This wire end brush is designed for decarbonising cylinder head ports and engine components. 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. Its size and shape makes it ideal for hard-to-reach areas such as drill holes, recesses and corners. Fitted with a 6mm round shank. Compatible with most drill drivers and drills with a 13mm chuck.
