The Novoflex B tube brush from Osborn is a self-centering honing tool specifically designed for finishing surfaces and edge breaking. With a bristle composition of flexible silicon carbide balls, the brush adapts perfectly to various surfaces, allowing for a gentle grinding process. The total length of the brush is 200 mm, with the brush attachment measuring 70 mm in length and 29 mm in diameter. This brush is ideal for processing irregular holes and produces uniformly finely ground surfaces with a high bearing ratio, also known as a plateau finish. The use of grinding oil is recommended to extend the tool's lifespan and achieve optimal results. The brush can be used on both hand drills and stationary machines, with a recommended speed of 350 to 700 min-1. The tube brush is suitable for various materials such as steel, aluminum, and cast iron.
