FLEXIBLE BORE BRUSHES - Abrasive-embedded balls on the ends of flexible nylon stems remove material and leave a smooth surface finish on the inside of cylinders, tubes and pipes. Increased contact outperforms standard nylon tube brushes in burr removal.
NYLON STEMS - Flexible stems evenly distribute pressure and self center in the cylinder.
LONG LIFE - Silicon carbide abrasive provides long operational life, lowering total cost compared to other brushes and effectively finishing difficult materials.
CROSS HATCH PATTERN - Helps to seat piston rings and retains oil for lubrication in a combustion cylinder.
