The Novoflex B tube brush from Osborn is a self-centering honing tool specifically designed for surface treatment. With a bristle made of flexible silicon carbide balls, it allows for a gentle grinding process that adapts optimally to the respective surface. This brush is excellent for edge breaking, finishing surfaces, and can also be used in irregular holes. The uniformly finely ground surfaces achieved with this brush feature a high bearing ratio, resulting in a so-called plateau finish. The tube brush has an overall length of 200 mm and is designed for use on handheld drills as well as stationary machines. To achieve the best results, it should be used with grinding oil, and the recommended speed is between 350 and 700 RPM.
